説明
The 810252I is a high performance, low jitter/low phase noise VCXO. The 810252I uses a low frequency and low cost pullable crystal to achieve jitter attenuation for synchronous Ethernet applications. The 810252I can take an input of 25MHz and produce two LVCMOS outputs 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.
