SY89835U
2.5V, 2GHz (3.2 Gbps) Ultra-Precision,
Differential 1:2 LVDS Fanout Buffer with
Internal Termination and Fail Safe Input General Description
The SY89835U is a 2.5V, high-speed 2GHz differential
Low Voltage Differential Swing (LVDS) 1:2 fanout buffer
optimized for ultra-low skew applications. Within device
skew is guaranteed to be less than 20ps over supply
voltage and temperature. A unique Fail-Safe Input (FSI)
protection prevents metastable conditions when no
signal is present or when the selected input clock fails to
a DC voltage (voltage between the pins of the
differential input drops sufficiently below 100 mV).
The SY89835U is part of Micrel’s high-speed clock
synchronization family. For applications that require a
different I/O combination, consult Micrel’s web site, and
choose from a comprehensive product line of highspeed, low-skew fanout buffers, translators and clock
generators.
