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.
