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:
