Ultra Series™ Crystal Oscillator Si548 Data Sheet Ultra Low Jitter I2C Programmable XO (95 fs), 0.2 to 1500 MHz The Si548 Ultra Series™ oscillator utilizes Skyworks Solutions’ advanced 4th generation DSPLL® technology to provide an ultra-low jitter, low phase noise clock at any output frequency. The device is user-programmed via simple I2C commands to provide any frequency from 0.2 to 1500 MHz with <1 ppb resolution and maintains exceptionally low jitter for both integer and fractional frequen.

Si548 Features

* I2C programmable to any frequency from 0.2 to 1500 MHz with < 1 ppb resolution

* Ultra low jitter: 95 fs Typ RMS (12 kHz

* 20 MHz)

* I2C interface supports 100 kbps, 400 kbps, and 1 Mbps (Fast Mode Plus)

* Low additive jitter when I2C is active (15 fs Typ)
