description features 5v/3.3v 2.5gbps high-speed differential receiver SY88927V final 3.3v and 5v power supply options maximum frequency > 3.0ghz internal 75k ? input pull-down resistors faster version of sy100el16v 100k ecl compatible i/o improved output waveform characteristics available in 8-pin (3mm) msop and soic package 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 high- frequency sources. the SY88927V provides a v bb output for either single- ended use or as a dc bias for ac coupling to the device. the v bb pin should be used only as a bias for the SY88927V as its current sink/source capability is limited. whenever used, the v bb pin should be bypassed to ground via a 0.01 f capacitor. under open input conditions (pulled to v ee ), internal input clamps will force the q output low. pin names pin function d data inputs q data outputs v bb reference voltage output (available in msop or soic packages) pin configuration/block diagram 1 nc d /d v bb 8v cc q /q v ee 7 6 5 2 3 4 1 rev.: c amendment: /0 issue date: july 2000
