The SY88927V is a 2.5Gbps high-speed differential
receiver. The device is functionally equivalent to the
EL16V devices, with higher performance capabilities. With
output transition times significantly faster than the EL16V,
the SY88927V is ideally suited for interfacing with highfrequency sources.
The SY88927V provides a VBB output for either singleended use or as a DC bias for AC coupling to the device.
The VBB pin should be used only as a bias for the
SY88927V as its current sink/source capability is limited.
Whenever used, the VBB pin should be bypassed to
ground via a 0.01µF capacitor.
Under open input conditions (pulled to VEE), internal
input clamps will force the Q output LOW.

NOTES:
1. This table replaces the three tables traditionally seen in ECL 100K data books. Outputs are terminated through a 50Ω resistor to –2.0V except where
otherwise specified on the individual data sheets.
2. Guaranteed HIGH Signal for all inputs.
3. Guaranteed LOW Signal for all inputs.
