CPPFXC4LT-A7BR-20.0PD

Oscillators Overview

The CPPFXC4LT-A7BR-20.0PD is a field-programmable CMOS output clock oscillator manufactured by Cardinal Components Inc. It operates at a nominal frequency of 20.0 MHz with a minimum supply voltage of 4.5 V and a maximum of 5.5 V. The device features through-hole mounting in a DIP-8/4 package, measuring 13.2mm x 13.2mm x 5.6mm. It supports an operating temperature range from -40 °C to 85 °C and includes tri-state functionality for enable/disable control.

Oscillators Feature Summary

• Field programmable blank oscillator capable of being programmed twice using PG-2000P or PG-3000 instruments
• CMOS output signal with tri-state capability for system power management
• Through-hole mount construction in a standard DIP-8/4 ceramic package

Oscillators Applications

• Driving A/Ds and D/As
• Digital video systems
• Ethernet and GbE interfaces
• SONET/SDH/DWDM networks

Oscillators Procurement Notes

Verify the specific frequency tolerance and stability requirements against the application needs, as the base part number indicates a programmable blank oscillator. Confirm that the required programming instrument (PG-2000P or PG-3000) is available for final configuration. Ensure the DIP-8/4 through-hole package aligns with the PCB layout and assembly capabilities. Check RoHS compliance status if restricted substances are a concern for the target market.

Oscillators Selection Notes

Select this component when a custom frequency is required without long lead times associated with factory-programmed units. The CMOS output is suitable for digital logic interfacing. Consider the physical size constraints of the DIP-8/4 package during board design. Verify that the 5V supply voltage matches the system power rails. The tri-state feature allows for bus sharing or power-down modes in complex designs.

Oscillators Part Context

This part belongs to the CPPFX series of field-programmable crystal oscillators from Cardinal Components Inc. The series offers flexibility by allowing end-users to program the frequency on-site. The 'C' denotes CMOS output, '4' indicates half-size packaging, and 'L' specifies the voltage option. This series replaces fixed-frequency crystals in applications requiring rapid prototyping or multi-standard support.

Oscillators Replacement Considerations

Direct replacement requires matching the DIP-8/4 through-hole form factor and 5V CMOS output. Other parts in the CPPFX series with different frequencies or package styles may fit mechanically but require electrical verification. Ensure the substitute also supports the required operating temperature range and tri-state functionality.
