General Description

The SY89200U is a 2.5V precision, high-speed, integrated

clock divider and LVDS fanout buffer capable of handling

clocks up to 1.5GHz. Optimized for communications

applications, the three independently controlled output

banks are phase matched and can be configured for pass

through (÷1), ÷2 or ÷4 divider ratios.

The differential input includes Micrel’s unique, 3-pin input

termination architecture that allows the user to interface to

any differential signal path. The low-skew, low-jitter

outputs are LVDS-compatible with extremely fast rise/fall

times guaranteed to be less than 150ps.

The EN (enable) input guarantees that the ÷1, ÷2 and ÷4

outputs will start from the same state without any runt

pulse after an asynchronous master rest (MR) is asserted.

This is accomplished by enabling the outputs after a four-

clock delay to allow the counters to synchronize.

The SY89200U is part of Micrel’s Precision Edge

family.
