5V/3.3V 2.5Gbps HIGH-SPEED DIFFERENTIAL RECEIVER FEATURES DESCRIPTION ■ 3.3V and 5V power supply options ■ Maximum frequency > 3.0GHz ■ Internal 75KΩ input pull-down resistors ■ ■ ■ ■ SY88927V 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.

Duty cycle skew is the difference between a tPLH and tPHL propagation delay through a device. 2. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between VPP min. and 1V. The lower end of the CMR range varies 1:1 with VEE. 3.
