For distances greater than 1km the shorter wavelength channel will always arrive at the receiver before the longer wavelength channel. Chromatic skew is linear with distance. A 10 km link has a Maximum Chromatic Skew of 11 ns. A 50 km link has a Maximum Chromatic Skew of 55 ns. Additional Skew due to internal fiber length variation will be kept to less than 2ns for the total link. 10 km link - Total Skew <13ns 50 km link - Total Skew <57ns -2- PRELIMINARY FEATURES - 4 Optically De-multiplexed Channels - Operation in the 1.5m low loss window - Data rate 1.25Gb/s per channel - 4 x 9 Pin Footprint - Low power consumption - For Singlemode applications - Available with SC Connector - Small Package RECEIVER CHARACTERISTICS 5V ( PER CHANNEL T= 0 TO 65C ) Parameter Symbol Minimum Typical Wavelength 1495 Average Optical Sensitivity1: -14 B1 -17 B2 -19 B3 Average max Input Power B1 B2 B3 Data Rate 1.25 Supply Voltage Vcc 4.75 5.0 Supply Current Icc Power Dissipation P Output High Voltage VOH Vcc-1.03 Output Low Voltage VOL Vcc-1.82 Rise/Fall Times Tr/Tf Signal Detect Threshold-Assertion: B1 B2 B3 Signal Detect Threshold - Deassertion: -22.5 Max Performance B1 -25.5 Max performance B2 -27.5 Max Performance B3 Data dependent Jitter Hysteresis 2.0 Signal Detect Timing-Assertion Signal Detect Timing-Deassertion Maximum 1567 Unit nm dBm dBm -3.0 -3.0 -3.0 5.25 200 1050 Vcc-0.89 Vcc-1.63 0.25 Gbps V mA mW V V ns dBm -14 -17 -19 dBm 0.1 100 100 ns dB s s MODULE CHARACTERISTICS ( T= 0C to 65C, 50% DUTY CYCLE ) Part Number Power budget (dB) Transmission distance using 0.3dB/km (km) MRTW4SCD5B1-5D MRTW4SCD5B2-5D MRTW4SCD5B3-5D 6 12 16 20 40 53 * For distances less than 10km, inline attenuation needs to be added to avoid receiver saturation. 1 Optical Sensitivity measured at BER of 10-10 using a of 223 -1 PRBS. -3- PRELIMINARY ABSOLUTE MAXIMUM RATINGS (5V) PARAMETER SYMBOL Supply Voltage Vcc Output Current Io Operating Temp(case) Storage Temp Lead Soldering Temp/Time Grounding Post Temp/Time RATING 5.25 50 0 to +65 -40 to+85 240/6 300/10 UNIT VOLTS mA C C C/S C/S Pin Assignments/ Channel Pin 1 2 3 4 5 6 7 8 9 Function GND RECEIVE DATA RECEIVE DATA SIGNAL DETECT RX Vcc TX Vcc TRANSMIT DATA TRANSMIT DATA GND -4- PRELIMINARY Outline Drawing 5.950 4.000 1.375 0.615 2.900 1.100 0.050 1.015 0.374 0.650 max 0.650 0.226 0.380 5.250 0.350 0.100 0.300 Tap 4-40, 1/4 Deep 7 Places 5.050 3.100 1.500 0.800 0.062 2 Places 0.800 0.020 9 Places 0.10 0.133 0.100 0.750 1.250 1.250 1.250 0.350 0.750 -5- PRELIMINARY Pinout Diagram RX Vcc TX Vcc 10f 0.1f 0.1f 10f Signal Detect Receive Data 50 50 Transmit Data Receive Data 50 50 Transmit Data 1 9 NOTES: 1. 2.
