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 8−lead 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
single−ended or differential input mode. When single−ended cap
coupled, VBB output is tied to the D input and D is driven for a
non−inverting 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 single−ended direct
connection use an external voltage reference source such as a resistor
divider. Do not use VBB for a single−ended direct connection or port to
another device.
