General Description
The SY89833AL is a lower noise version of the SY89833L
3.3V, high-speed 2GHz Low Voltage Differential Swing
(LVDS) 1:4 fanout buffer. 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 SY89833AL is part of Micrel’s high-speed clock
synchronization
SY89832U provides similar functionality while operating
from a 2.5V ±5% supply. For applications that require a
different I/O combination, consult the Micrel website at:
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 can be found on Micrel’s web site at:
