SIT3373AC-2E9-28NG500.000000

Oscillators Overview

The SiTime SIT3373AC-2E9-28NG500.000000 is a MEMS-based Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 500 MHz. It utilizes LVDS output signaling and requires a 2.8V supply voltage. The device features a frequency stability of ±35 ppm and an absolute pull range of ±760 ppm, enabling precise frequency tuning. It operates within a temperature range of -20°C to +70°C and is housed in a compact 7 mm x 5 mm surface-mount package with six no-lead exposed pad terminals.

Oscillators Feature Summary

• DualMEMS technology for low-jitter performance
• Voltage-controlled operation with wide pull range
• LVDS differential output interface
• Compact 7x5mm surface-mount footprint

Oscillators Applications

• Low-jitter clock distribution systems
• Telecommunications infrastructure equipment
• High-speed data transmission interfaces
• Test and measurement instrumentation

Oscillators Procurement Notes

Verify the specific ordering suffix against the official SiTime datasheet to ensure compatibility with required voltage levels, output types, and frequency tolerances. Confirm that the 2.8V supply requirement aligns with the target system design. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the lead-free package type matches the PCB assembly capabilities.

Oscillators Selection Notes

Select this component when a stable 500 MHz reference with voltage control capability is required. The ±35 ppm stability suits applications needing moderate precision without the cost of higher-grade oscillators. The LVDS output is ideal for noise-sensitive high-speed digital environments. Consider the ±760 ppm pull range for applications requiring significant frequency adjustment during operation.

Oscillators Part Context

This part belongs to the SiTime Elite Platform family of programmable MEMS oscillators. The SIT3373 series specifically targets VCXO applications, offering tunability not found in standard fixed-frequency oscillators. It replaces traditional quartz VCXOs by providing better shock resistance and smaller form factors while maintaining comparable or superior jitter performance.

Oscillators Replacement Considerations

Direct replacements must match the 500 MHz frequency, LVDS output, and 2.8V supply. Verify pinout compatibility for the 6-no-lead package. Cross-reference with other SiTime VCXO models like the SIT3373AC-4E3 variant if different supply voltages are needed.
