CPPFXC7T-A7BR-28.63636TS

Oscillators Overview

The CPPFXC7T-A7BR-28.63636TS is a field-programmable CMOS output clock oscillator manufactured by Cardinal Components Inc. It operates at a nominal frequency of 28.63636 MHz with a frequency stability of ±25 ppm. The device utilizes a surface-mount ceramic package measuring 7.0mm x 5.0mm x 1.7mm and features four pins. 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 using PG-3200 or PG-3000 instruments
• CMOS output signal with tri-state capability
• Sealed finished custom oscillator design

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 28.63636 MHz target. Confirm the 'T' designation indicates TTL output if that interface is required, as other variants offer CMOS. Ensure the A7 suffix corresponds to the -40°C to +85°C temperature range needed for the application environment.

Oscillators Selection Notes

Select this model when a sealed, custom-frequency oscillator is required for high-density designs. The 7050mm ceramic package offers robustness compared to plastic options. Consider the field-programmable nature for inventory flexibility, allowing blank units to be programmed on-site rather than stocking numerous fixed frequencies.

Oscillators Part Context

This component belongs to the CPPFX series of field-programmable crystal oscillators. It allows manufacturers to program blank oscillators in the field within seconds, providing a sealed finished custom oscillator. This approach reduces inventory complexity by enabling the stocking of generic blank units that can be configured to specific frequencies as needed.
