Oscillators Procurement Notes

Verify the complete part number including suffixes to ensure correct output format, voltage, and stability specifications. Confirm package dimensions and reflow profile requirements against PCB design constraints. Check availability status as distribution may vary by region. Ensure compatibility with system power supply noise levels given the integrated regulation features.

Oscillators Selection Notes

Select this component when low jitter and high dynamic stability are critical for 200 MHz differential clocking. Consider the LVPECL output interface for compatibility with downstream logic. Evaluate the ±25 ppm stability against system timing budgets. The integrated noise filtering simplifies board layout by reducing external component count compared to traditional quartz solutions.

Oscillators Part Context

This model belongs to the SiT3372 Elite Platform series, designed for ultra-low jitter applications. It replaces custom quartz VCXOs by offering factory programmability without long lead times. The device supports frequencies from 1 MHz to 220 MHz, providing designers flexibility in optimizing clock configurations for telecom and networking standards.

Oscillators Replacement Considerations

Direct substitutes include other SIT3372 variants with matching 200 MHz frequency, LVPECL output, and ±25 ppm stability, such as SIT3372AI-1E2-25NE200.000000 if temperature range differences are acceptable. Verify pinout and electrical characteristics before substitution.
