CPPFXC7LT-A7BR-12.288TS

Oscillators Overview

The CPPFXC7LT-A7BR-12.288TS is a field-programmable CMOS clock oscillator manufactured by Cardinal Components Inc. It operates at a nominal frequency of 12.288 MHz with a ±20 ppm stability rating. The device features a tri-state output and an enable/disable function, powered by a standard 5V supply. It utilizes a surface-mount ceramic package measuring 7.0mm x 5.0mm x 1.7mm. Designed for rapid on-site configuration using the PG-3000 programming instrument, it supports reprogramming up to two times.

Oscillators Feature Summary

• Field programmable blank oscillator capable of being programmed within seconds using the PG-3000 instrument
• Supports reprogramming up to two times for flexible design adjustments
• Features tri-state output logic with integrated enable and disable functionality

Oscillators Applications

• Driving A/D and D/A converters
• FPGA clocking applications
• Digital video systems
• Ethernet and GbE interfaces
• SONET/SDH/DWDM networking equipment

Oscillators Procurement Notes

Verify that the specific part number suffix matches the required voltage and stability specifications. Confirm compatibility with the PG-3000 field programming instrument if on-site customization is planned. Ensure the ceramic SMD package dimensions align with the target PCB footprint requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a fixed-frequency crystal is insufficient for dynamic design needs. The field-programmable nature allows for last-minute frequency changes without replacing hardware. Consider the ±20 ppm stability and 5V operation as primary constraints. Verify that the application environment falls within the specified commercial temperature range.

Oscillators Part Context

This model belongs to the CPPFX series of field-programmable oscillators from Cardinal Components Inc. The series offers customizable frequencies ranging from 1.000 to 133.000 MHz. Unlike standard fixed oscillators, these devices provide sealed finished custom oscillators that can be programmed in the field, reducing inventory complexity for manufacturers dealing with multiple frequency variants.

Oscillators Replacement Considerations

Direct replacements must match the CPPFX series field-programmable architecture and 5V supply requirement. Generic fixed-frequency oscillators cannot substitute this part due to the lack of programmability. Verify that any alternative supports the same 7x5mm ceramic package and tri-state CMOS output characteristics.
