SiT9501 - SiTime

SiT9501 Ultra-low Jitter Differential XO

The SiT9501 is a differential MEMS oscillator that is engineered for low-jitter applications requiring standard frequencies from 25 MHz to 644.53125 MHz. In addition to standard differential signaling types, a unique FlexSwing™ output-driver performs like LVPECL and provides independent control of voltage swing and DC offset to simplify interfacing with chip.
