The SY89250V is a differential PECL/ECL receiver/buffer
in a space saving (2mm
× 2mm) MLF package. The device
is functionally equivalent to the SY100EL16VC, but features
a 70% smaller footprint. It provides a V
BB output for either
single-ended application or as a DC bias for AC-coupling to
the device.
The SY89250V provides an /EN input which is synchro-
nized with the data input (D) signal in a way that provides
glitchless gating of the QHG and /QHG outputs. When the /EN
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
the /EN goes HIGH, it will force the QHG LOW and the /QHG
HIGH on the next negative transition of the data input. If the
data input is LOW when the /EN goes HIGH, the next data
transition to a HIGH is ignored and QHG remains LOW and
/QHG remains HIGH. The next positive transition of the data
input is not passed on to the data outputs under these
conditions. The QHG and /QHG outputs remain in their dis-
abled state as long as the /EN input is held HIGH. The /EN
input has no influence on the /Q output and the data input is
passed on (inverted) to this output whether /EN is HIGH or
LOW. This configuration is ideal for crystal oscillator applica-
tions, where the oscillator can be free running and gated on
and off synchronously without adding extra counts to the
output.
