Oscillators Procurement Notes

Verify that the specific part number matches the required LVPECL output configuration and 25 MHz frequency. Confirm the package style corresponds to the design requirements for surface-mount assembly. Ensure the operating temperature range aligns with the environmental conditions of the target application. Cross-reference the manufacturer series designation to confirm compatibility with existing system components.

Oscillators Selection Notes

Select this component when a compact, field-programmable oscillator with LVPECL outputs is required. Consider the ±25 ppm stability for applications needing moderate precision. Evaluate the 3 V to 3.6 V supply voltage against available power rails. Assess the need for integrated real-time clock capabilities if timekeeping functions are necessary within the same footprint.

Oscillators Part Context

This component belongs to the CPPE series from Cardinal Components Inc., which specializes in field-programmable blank oscillators. The series allows for on-the-fly programming using instruments like the PG-3000 or PG-3100.
