SiT5021中文资料1 to 220 MHz, ±5 ppm Differential (VC)TCXO数据手册SiTime规格书

描述 Description

The SiT5021 is a programmable differential MEMS TCXO that supports LVPECL and LVDS output signaling types. This differential oscillator covers any frequency between 1 to 220 MHz, with RMS phase jitter of 0.6 ps. The SiT5021 is available in any combination of voltage (2.5 V to 3.3 V), pull range, frequency stability (±5 ppm) and package (3225, 5032, 7050) options. This programmability enables designers to optimize the clock configuration while eliminating the long lead time and customization costs associated with quartz TCXOs where each frequency is custom built.
