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.
