SIT3372AC-4E9-33NG148.350000

Oscillators Overview

The SiTime SIT3372AC-4E9-33NG148.350000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at 148.35 MHz. It utilizes DualMEMS temperature sensing and TurboCompensation technology for dynamic performance against thermal gradients, shock, and vibration. The device features integrated on-chip regulators to filter power supply noise, eliminating the need for external LDOs. It supports HCSL output signaling with a 3.3V supply voltage range of 2.97V to 3.63V. The component is housed in a 6-SMD, No Lead package with an exposed pad, designed for low-jitter applications in noisy environments.

Oscillators Procurement Notes

Verify the exact part number suffix against official SiTime documentation to confirm output signaling type and stability specifications. Ensure the procurement source provides valid RoHS compliance data. Confirm that the supplier offers genuine components with traceable manufacturing batches. Check for any specific handling requirements related to the exposed pad surface mount package during assembly.

Oscillators Selection Notes

Select this VCXO when design requirements include differential HCSL outputs and operation within a 3.3V supply environment. Consider this component for applications needing immunity to mechanical shock and vibration due to MEMS construction. Evaluate the need for factory-programmed pull ranges and specific frequency stability before ordering. Ensure the PCB layout accommodates the 6-SMD no-lead package dimensions and thermal pad requirements.

Oscillators Part Context

This model belongs to the SiT3372 family of ultra-low jitter differential VCXOs from SiTime. The series covers a frequency range from 1 MHz to 220 MHz, engineered for timing applications where signal integrity is critical. The specific variant identified uses HCSL output signaling and operates at 148.35 MHz, distinguishing it from LVDS or other output format variants within the same product line.

Oscillators Replacement Considerations

Direct replacement requires matching the 148.35 MHz frequency, HCSL output format, and 3.3V supply voltage. Verify pin compatibility for the 6-SMD no-lead package. Consult SiTime documentation for alternative part numbers with identical electrical characteristics if this specific suffix is unavailable.
