The devices are fabricated using TI's advanced double-poly CMOS process (microCMOS). The encode portion of each device consists of an input gain adjust amplifier, an active RC pre-filter which eliminates very high frequency noise prior to entering a switched-capacitor band-pass filter that rejects signals below 200 Hz and above 3400 Hz. Also included are auto-zero circuitry and a companding coder which samples the filtered signal and encodes it in the companded -law or A-law PCM format. The decode portion of each device consists of an expanding decoder, which reconstructs the analog signal from the companded -law or A-law code, a low-pass filter which corrects for the sin x/x response of the decoder output and rejects signals above 3400 Hz followed by a single-ended power amplifier capable of driving low impedance loads. The devices require two 1.536 MHz, 1.544 MHz or 2.048 MHz transmit and receive master clocks, which may be asynchronous; transmit and receive bit clocks, which may vary from 64 kHz to 2.048 MHz; and transmit and receive frame sync pulses. The timing of the frame sync pulses and PCM data is compatible with both industry standard formats. Connection Diagram Figure 1. Plastic Chip Carriers (Top View) Package Number FN0020A Figure 2.

Functional Description POWER-UP When power is first applied, power-on reset circuitry initializes the COMBO and places it into a power-down state. All non-essential circuits are deactivated and the DX and VFRO outputs are put in high impedance states. To power-up the device, a logical low level or clock must be applied to the MCLKR/PDN pin and FSX and/or FSR pulses must be present. Thus, 2 power-down control modes are available. The first is to pull the MCLKR/PDN pin high; the alternative is to hold both FSX and FSR inputs continuously low--the device will power-down approximately 1 ms after the last FSX or FSR pulse. Power-up will occur on the first FSX or FSR pulse. The TRISTATE PCM data output, DX, will remain in the high impedance state until the second FSX pulse. SYNCHRONOUS OPERATION For synchronous operation, the same master clock and bit clock should be used for both the transmit and receive directions. In this mode, a clock must be applied to MCLKX and the MCLKR/PDN pin can be used as a powerdown control. A low level on MCLKR/PDN powers up the device and a high level powers down the device. In either case, MCLKX will be selected as the master clock for both the transmit and receive circuits. A bit clock must also be applied to BCLKX and the BCLKR/CLKSEL can be used to select the proper internal divider for a master clock of 1.536 MHz, 1.544 MHz or 2.048 MHz. For 1.544 MHz operation, the device automatically compensates for the 193rd clock pulse each frame. With a fixed level on the BCLKR/CLKSEL pin, BCLKX will be selected as the bit clock for both the transmit and receive directions. Table 1 indicates the frequencies of operation which can be selected, depending on the state of BCLKR/CLKSEL. In this synchronous mode, the bit clock, BCLKX, may be from 64 kHz to 2.048 MHz, but must be synchronous with MCLKX. Each FSX pulse begins the encoding cycle and the PCM data from the previous encode cycle is shifted out of the enabled DX output on the positive edge of BCLKX. After 8 bit clock periods, the TRI-STATE DX output is returned to a high impedance state. With an FSR pulse, PCM data is latched via the DR input on the negative edge of BCLKX (or BCLKR if running). FSX and FSR must be synchronous with MCLKX/R. Table 1.

MCLKX and MCLKR must be 2.048 MHz for the TP3057, or 1.536 MHz, 1.544 MHz for the TP3054, and need not be synchronous. For best transmission performance, however, MCLKR should be synchronous with MCLKX, which is easily achieved by applying only static logic levels to the MCLKR/PDN pin. This will automatically connect MCLKX to all internal MCLKR functions (see Pin Description above). For 1.544 MHz operation, the device automatically compensates for the 193rd clock pulse each frame. FSX starts each encoding cycle and must be synchronous with MCLKX and BCLKX. FSR starts each decoding cycle and must be synchronous with BCLKR. BCLKR must be a clock, the logic levels shown in Table 1 are not valid in asynchronous mode. BCLKX and BCLKR may operate from 64 kHz to 2.048 MHz. SHORT FRAME SYNC OPERATION The COMBO can utilize either a short frame sync pulse or a long frame sync pulse. Upon power initialization, the device assumes a short frame mode. In this mode, both frame sync pulses, FSX and FSR, must be one bit clock period long, with timing relationships specified in Figure 4. With FSX high during a falling edge of BCLKX, the next rising edge of BCLKX enables the DX TRI-STATE output buffer, which will output the sign bit. The following seven rising edges clock out the remaining seven bits, and the next falling edge disables the DX output. With FSR high during a falling edge of BCLKR (BCLKX in synchronous mode), the next falling edge of BCLKR latches in the sign bit. The following seven falling edges latch in the seven remaining bits. All four devices may utilize the short frame sync pulse in synchronous or asynchronous operating mode. LONG FRAME SYNC OPERATION To use the long frame mode, both the frame sync pulses, FSX and FSR, must be three or more bit clock periods long, with timing relationships specified in Figure 5. Based on the transmit frame sync, FSX, the COMBO will sense whether short or long frame sync pulses are being used. For 64 kHz operation, the frame sync pulse must be kept low for a minimum of 160 ns. The DX TRI-STATE output buffer is enabled with the rising edge of FSX or the rising edge of BCLKX, whichever comes later, and the first bit clocked out is the sign bit. The following seven BCLKX rising edges clock out the remaining seven bits. The DX output is disabled by the falling BCLKX edge following the eighth rising edge, or by FSX going low, whichever comes later. A rising edge on the receive frame sync pulse, FSR, will cause the PCM data at DR to be latched in on the next eight falling edges of BCLKR (BCLKX in synchronous mode). All four devices may utilize the long frame sync pulse in synchronous or asynchronous mode. In applications where the LSB bit is used for signalling, with FSR two bit clock periods long, the decoder will interpret the lost LSB as "1/2" to minimize noise and distortion. TRANSMIT SECTION The transmit section input is an operational amplifier with provision for gain adjustment using two external resistors, see Figure 8. The low noise and wide bandwidth allow gains in excess of 20 dB across the audio passband to be realized. The op amp drives a unity-gain filter consisting of RC active pre-filter, followed by an eighth order switched-capacitor bandpass filter clocked at 256 kHz. The output of this filter directly drives the encoder sample-and-hold circuit. The A/D is of companding type according to -law (TP3054) or A-law (TP3057) coding conventions. A precision voltage reference is trimmed in manufacturing to provide an input overload (tMAX) of nominally 2.5V peak (see Transmission Characteristics). The FSX frame sync pulse controls the sampling of the filter output, and then the successive-approximation encoding cycle begins. The 8-bit code is then loaded into a buffer and shifted out through DX at the next FSX pulse. The total encoding delay will be approximately 165 s (due to the transmit filter) plus 125 s (due to encoding delay), which totals 290 s. Any offset voltage due to the filters or comparator is cancelled by sign bit integration. 4 Submit Documentation Feedback Copyright (c) 2005-2013, Texas Instruments Incorporated Product Folder Links: TP3054-X TP3057-X TP3054-X, TP3057-X www.ti.com SNOSBY2C - MARCH 2005 - REVISED APRIL 2013 RECEIVE SECTION The receive section consists of an expanding DAC which drives a fifth order switched-capacitor low pass filter clocked at 256 kHz. The decoder is A-law (TP3057) or -law (TP3054) and the 5th order low pass filter corrects for the sin x/x attenuation due to the 8 kHz sample/hold. The filter is then followed by a 2nd order RC active postfilter/power amplifier capable of driving a 600 load to a level of 7.2 dBm. The receive section is unity-gain. Upon the occurrence of FSR, the data at the DR input is clocked in on the falling edge of the next eight BCLKR (BCLKX) periods. At the end of the decoder time slot, the decoding cycle begins, and 10 s later the decoder DAC output is updated. The total decoder delay is 10 s (decoder update) plus 110 s (filter delay) plus 62.5 s (1/2 frame), which gives approximately 180 s. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.

In applications where the printed circuit board may be plugged into a "hot" socket with power and clocks already present, an extra long ground pin in the connector should be used. All ground connections to each device should meet at a common point as close as possible to the GNDA pin. This minimizes the interaction of ground return currents flowing through a common bus impedance. 0.1 F supply decoupling capacitors should be connected from this common ground point to VCC and VBB, as close to device pins as possible. For best performance, the ground point of each CODEC/FILTER on a card should be connected to a common card ground in star formation, rather than via a ground bus. This common ground point should be decoupled to VCC and VBB with 10 F capacitors. RECEIVE GAIN ADJUSTMENT For applications where a TP3050 family CODEC/filter receive output must drive a 600 load, but a peak swing lower than 2.5V is required, the receive gain can be easily adjusted by inserting a matched T-pad or -pad at the output. Table 2 lists the required resistor values for 600 terminations. As these are generally non-standard values, the equations can be used to compute the attenuation of the closest practical set of resistors. It may be necessary to use unequal values for the R1 or R4 arms of the attenuators to achieve a precise attenuation. Generally it is tolerable to allow a small deviation of the input impedance from nominal while still maintaining a good return loss. For example a 30 dB return loss against 600 is obtained if the output impedance of the attenuator is in the range 282 to 319 (assuming a perfect transformer). Figure 6.
