SIT3372AC-4B2-30NB70.656000

Oscillators Overview

The SIT3372AC-4B2-30NB70.656000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) from SiTime, operating at a nominal frequency of 70.656 MHz. It features HCSL output signaling and supports a pull range of ±170 ppm with a frequency stability of ±25 ppm. The device operates on a 3.0 V supply within an industrial temperature range of -40 °C to +85 °C. Packaged in a 6-pin surface-mount DILCC form factor, it integrates on-chip regulators for power noise filtering.

Oscillators Feature Summary

• Utilizes DualMEMS temperature sensing and TurboCompensation technology for resistance to thermal gradients, shock, and vibration.
• Integrates multiple on-chip regulators to filter power supply noise, eliminating the need for external LDOs.
• Factory programmed for specific combinations of frequency, stability, voltage, output signaling, and pull range.

Oscillators Applications

• Telecommunications systems requiring low-jitter clocking
• Networking equipment with noisy environment constraints
• Industrial applications needing variable pullable frequencies
