General Description

The 810251I is a high performance, low jitter/low phase noise

VCXO. The 810251i uses a low frequency and low cost pullable

crystal to achieve jitter attenuation for synchronous Ethernet

applications. The 810251I can take an input of either 25MHz or

125MHz and produce a single LVCMOS output of 25MHz.

The device is packaged in a small 16 lead TSSOP package and is

ideal for use on space constrained boards typically encountered in

most synchronous ethernet applications.
