MC100EPT21
3.3V Differential
LVPECL/LVDS/CML to
LVTTL/LVCMOS Translator
The MC100EPT21 is a Differential LVPECL/LVDS/CML to
LVTTL/LVCMOS translator. Because LVPECL (Positive ECL),
LVDS, and positive CML input levels and LVTTL/LVCMOS output
levels are used, only +3.3 V and ground are required. The small
outline 8lead SOIC package makes the EPT21 ideal for applications
which require the translation of a clock or data signal.
The VBB output allows this EPT21 to be cap coupled in either
singleended or differential input mode. When singleended cap
coupled, VBB output is tied to the D input and D is driven for a
noninverting buffer, or VBB output is tied to the D input and D is
driven for an inverting buffer. When cap coupled differentially, VBB
output is connected through a resistor to each input pin. If used, the
VBB pin should be bypassed to VCC via a 0.01 mF capacitor. For
additional information see AND8020/D. For a singleended direct
connection use an external voltage reference source such as a resistor
divider. Do not use VBB for a singleended direct connection or port to
another device.
