Programmable Oscillators Procurement Notes

Verify that the specific part number matches the required PECL output type and SMD package configuration. Confirm the operating temperature range aligns with system requirements. Ensure compatibility with the PG-3000 field oscillator programming instrument for final frequency customization. Check RoHS compliance status if mandated by project specifications.

Programmable Oscillators Selection Notes

Select this component when a PECL output interface is required for high-speed clocking applications. Consider the 1 MHz to 133 MHz frequency range and the 3.3 V supply voltage constraints. The dual frequency select feature makes it suitable for designs needing flexible frequency switching without hardware changes. Verify the SMD footprint dimensions fit the PCB layout.

Programmable Oscillators Part Context

The CPPE9 belongs to the Cardinal Components field-programmable oscillator series, designed for customizable frequency generation. It complements other models like the CPPDC and CPPLT series by offering PECL outputs in a compact surface-mount form factor. This series emphasizes flexibility through field programming rather than fixed factory settings.

Programmable Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires matching the PECL output type, 8-pin SMD package, and 3.3 V supply voltage. Verify frequency range and physical dimensions before substitution.
