The SiT9387 is an AEC-Q100, ultra-low-jitter differential oscillator that supports any frequency from 220.000001 to 725 MHz in 1 Hz increments. Based on SiTime's unique Elite Platform™, this device delivers exceptional dynamic performance of 0.23 ps jitter (typ.) and ±25 ppm in the presence of common environmental hazards such as shock, vibration, power supply noise, EMI, and board bending.
The SiT9387 is available in the smallest 3.2 x 2.5 mm differential package in addition to the 7.0 x 5.0 mm package. This device supports all popular output signaling types including LVPECL, LVDS, and HCSL in combination with any voltage between 2.25 to 3.63 V.
