SIT3372AC-1E9-28NH204.800000

Oscillators Overview

The SiTime SIT3372AC-1E9-28NH204.800000 is a differential MEMS VCXO operating at 204.8 MHz with LVPECL output signaling. It functions within a 2.5 V to 2.75 V supply range and supports an absolute pull range of ±25 ppm. The device maintains frequency stability of ±25 ppm across the -20 °C to +70 °C industrial temperature range. Packaged in a compact 6-SMD, No Lead Exposed Pad form factor measuring 7.0 mm x 5.0 mm, it integrates on-chip regulators for power noise filtering.

Oscillators Feature Summary

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

Oscillators Applications

• Telecommunications systems requiring low-jitter clock signals
• Networking equipment demanding precise frequency control
• Industrial applications operating in noisy environments

Oscillators Procurement Notes

Verify the complete part number against official SiTime documentation to ensure correct suffix alignment. Confirm that the 'NH' package designation matches the required 6-SMD exposed pad footprint. Validate the 2.8V nominal supply requirement against system power rails. Ensure the LVPECL output format is compatible with downstream receiver inputs before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 204.8 MHz differential clock with LVPECL outputs is required. Choose based on the ±25 ppm pull range and stability specifications suitable for telecom or networking. Consider the 7x5mm package size for board space constraints. Verify compatibility with -20°C to +70°C operating temperatures for industrial deployment scenarios.

Oscillators Part Context

The SiT3372 series represents a family of ultra-low jitter differential MEMS VCXOs from 1 MHz to 220 MHz. This specific model belongs to the Elite Platform lineup, engineered for exceptional dynamic performance. It replaces custom quartz devices by offering factory programmability, which eliminates long lead times and customization costs associated with traditional oscillator manufacturing.

Oscillators Replacement Considerations

Direct cross-replacement requires matching the 204.8 MHz frequency, LVPECL output type, and ±25 ppm pull range. Verify that substitute components support the same 2.5V–2.75V supply voltage and 7x5mm package dimensions. Ensure equivalent jitter and phase noise specifications are met for signal integrity preservation.
