• Field programmable blank oscillator capable of being programmed twice
• CMOS output with tri-state functionality for enable/disable control
• Surface mount plastic package construction
• Compatible with PG-3000 and PG-3100 programming instruments

Oscillators Applications

• Driving A/D and D/A converters
• Digital video signal processing
• Ethernet and Gigabit Ethernet interfaces
• SONET/SDH and DWDM systems

Oscillators Procurement Notes

Verify the specific part number against official Cardinal Components documentation to confirm the exact frequency tolerance and stability class associated with the BR suffix. Ensure compatibility with the required programming hardware, such as the PG-3000 or PG-3100 series, for field configuration. Confirm that the plastic SMD package dimensions align with the target PCB footprint requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a custom frequency solution is required without waiting for factory lead times. The field-programmable nature allows for design flexibility and inventory reduction by stocking blank units. Verify that the CMOS output voltage levels match the receiving logic inputs. Consider the tri-state feature if bus sharing or power management during idle states is necessary for the application architecture.

Oscillators Part Context

This oscillator belongs to the CPPFX series of field-programmable crystal oscillators. The series offers various package styles including ceramic and plastic options, with frequencies ranging up to 133 MHz. The CPPFXC8 variant specifically denotes a full-size CMOS output in a plastic SMD package, providing a balance between performance and ease of integration into standard surface-mount assembly processes.

Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, ensure the replacement supports field programming capabilities if design flexibility is required. Verify that the pinout, package dimensions, and electrical characteristics such as rise/fall times and supply voltage are compatible with the existing circuit design.
