General Description
The SY89833L is a 3.3V, 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 is included for AC coupled applications.-
The SY89833L is part of Micrel’s high speed clock -
synchronization family. For 2.5V applications, the
SY89832U provides similar functionality while operating
from a 2.5V ±5% supply. For applications that require a
different I/O c consult the Micrel website at ombination,
www.micrel.com, and choose from a comprehensive
product line of high speed, low- -skew fanout buffers,
translators and clock generators.
Datasheets and support documentation are available on
Micrel’s web site at: www.micrel.com.
