CPPLC7-A7BP-40.68TS

Oscillators Overview

The CPPLC7-A7BP-40.68TS is a field-programmable CMOS output clock oscillator manufactured by Cardinal Components Inc. It operates at a nominal frequency of 40.68 MHz with a supply voltage range of 3 V to 3.6 V, typically utilizing 3.3 V. The device features a tri-state output and an enable/disable function, housed in a full-size ceramic surface-mount package measuring 7.0 mm x 5.0 mm x 1.7 mm. It supports operation within a temperature range of -40 °C to 85 °C and offers programmable frequency stability options.

Oscillators Feature Summary

• Field-programmable blank oscillator capability allowing frequency customization using PG-3000 or PG-3100 instruments
• CMOS output interface with tri-state functionality and dedicated enable/disable control
• Dual programming capability enabling the component to be programmed twice

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency stability suffix against official datasheets, as 'BP' indicates ±50 ppm but other variants exist. Confirm the operating temperature range code matches application requirements, noting that standard CPPFXC models may differ from the CPPC series. Ensure the correct packaging option (bulk vs. tube/reel) is selected based on production needs. Cross-reference the part number with the manufacturer's current catalog to confirm availability and revision status before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a customizable frequency solution is required for high-speed digital circuits. The full-size ceramic package provides robust mechanical stability compared to half-size alternatives. Consider the ±50 ppm stability rating if precise timing is critical for Ethernet or SONET applications. Verify compatibility with the PG-3000/PG-3100 programming tools if in-field configuration is planned. Ensure the 3.3 V supply voltage aligns with the target system's power architecture.

Oscillators Part Context

This part belongs to the CPPC series of field-programmable crystal oscillators from Cardinal Components Inc. The series includes various package styles such as full-size ceramic, half-size ceramic, and plastic SMD options. The CPPC designation specifically denotes a CMOS output oscillator with a 3.3 V supply voltage option. This family allows for significant design flexibility by supporting post-manufacturing frequency adjustments.

Oscillators Replacement Considerations

Direct substitutes include other CPPC series variants with matching frequencies or package sizes, such as CPPC7LZ-A7B6-XX.XXXX. Generic replacements must match the 7.0mm x 5.0mm footprint and CMOS tri-state logic levels.
