SiT3372 Model Information:

Description:

• The SiT3372 is a 1 MHz to 220 MHz differential MEMS VCXO designed for low-jitter applications. It utilizes SiTime’s DualMEMS® temperature sensing and TurboCompensation® technology to provide exceptional dynamic performance, resistance to airflow, thermal gradients, shock, and vibration. It also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO.

Features:

• Any frequency between 1 MHz and 220 MHz accurate to 6 decimal places.Widest pull range options: ±25, ±50, ±80, ±100, ±150, ±200, ±400, ±800, ±1600, ±3200 ppm.0.225 ps RMS phase jitter (typ) over 12 kHz to 20 MHz bandwidth.Frequency stability as low as ±15 ppm.Wide temperature range support from -40°C to 105°C.Industry-standard packages: 7.0 x 5.0 mm, 5.0 x 3.2 mm, 3.2 x 2.5 mm packages.
