SY89832U
2.5V Ultra-Precision 1:4 LVDS Fanout
Buffer/Translator with Internal Termination
Precision Edge^®
General Description
The SY89832U is a 2.5V, high-speed, 2GHz 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 20ps 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 Micrel's high-speed clock
synchronization family. For 3.3V applications, see
SY89833L or SY89833AL. For applications that require a
different I/O combination, consult Micrel's website at
www.micrel.com and choose from a comprehensive
product line of high-speed, low-skew fanout buffers,
translators and clock generators.
