3.3V / 5VECL Differential
Receiver/Driver with High
Gain and Enable Output
The EP16VC is a differential receiver/driver. The device is
functionally equivalent to the EP16 and LVEP16 devices but with high
gain and enable output.
The EP16VC provides an EN
data input (D) signal in a way that provides glitchless gating of the
QHG and QHG
When the EN
outputs.
signal is LOW, the input is passed to the outputs and
the data output equals the data input. When the data input is HIGH and
goes HIGH, it will force the QHG LOW and the QHG HIGH on the
EN
next negative transition of the data input. If the data input is LOW
when the EN
and Q
goes HIGH, the next data transition to a HIGH is ignored
remains LOW and QHG remains HIGH. The next positive
HG
transition of the data input is not passed on to the data outputs under
these conditions. The Q

state as long as the EN
influence on the Q

output and the data input is passed on (inverted) to
is HIGH or LOW. This configuration is ideal
for crystal oscillator applications where the oscillator can be free
running and gated on and off synchronously without adding extra
counts to the output.
