Oscillators Procurement Notes

Verify the specific ordering suffix against official RIVER ELETEC documentation to ensure alignment with required voltage, tolerance, and temperature specifications. Confirm that the 4-SMD package variant matches the target PCB footprint. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Oscillators Selection Notes

Select this oscillator when a low-voltage 0.9V CMOS clock source is required for space-constrained designs. Ensure the application environment remains within the -40°C to +85C operational range. Verify that the ±20 ppm frequency stability meets system synchronization requirements. Confirm compatibility with the host circuit's input logic levels and current drive capabilities.

Oscillators Part Context

This component belongs to the FCXO-07 series of ultra-low-jitter clock solutions designed for high-speed communications. While the broader series supports advanced applications like AI data centers and 1.6T optical transceivers, this specific model provides standard performance suitable for mobile and wireless modules. It represents a specialized quartz-based timing solution distinct from generic family offerings.

Oscillators Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, 0.9V Vdd, 4-SMD package, and ±20 ppm stability. Verify pinout compatibility and thermal characteristics. Consult manufacturer cross-reference lists for verified equivalents.
