General Description

The SY89832U is a 2.5V, high-speed, 2 GHz

differential, low voltage differential swing (LVDS)

1:4 fanout buffer optimized for ultra-low skew

applications. Within device skew is guaranteed to be

less than 20 ps over supply voltage and temperature.

The differential input buffer has a unique internal

termination design that allows access to the

termination network through a VT pin. This feature

allows the device to easily interface to different logic

standards. A VREF–AC reference output is included for

AC-coupled applications.

The SY89832U is a part of the high-speed clock

synchronization family. For 3.3V applications, see

SY89833L or SY89833AL.
