CPPFXC7Z-A7BR-4.0TS

Oscillators Overview

The CPPFXC7Z-A7BR-4.0TS is a field-programmable CMOS clock oscillator manufactured by Cardinal Components Inc. It operates at a nominal frequency of 4.0 MHz with a standard supply voltage of 5V. The device utilizes a surface-mount ceramic package measuring 7.0mm x 5.0mm x 1.7mm and features four pins. Key electrical characteristics include rise and fall times of 4 ns, an output load capacitance of 30 pF, and a frequency stability of 25%. It supports tri-state functionality with enable/disable control and operates within a temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Field programmable blank oscillator capable of being programmed twice using PG-2000P or PG-3000 instruments
• Provides sealed finished custom oscillator solutions with tri-state output capability
• Supports enable/disable function for power management and system control

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific programming instrument compatibility, such as PG-2000P or PG-3000, required for field configuration. Confirm that the order suffix BR indicates tape and reel packaging rather than bulk. Ensure the application environment falls within the specified -40°C to +85°C operating temperature range. Validate that the 25% frequency stability meets the design requirements for the target circuit.

Oscillators Selection Notes

Select this component when a customizable 4 MHz CMOS clock source is required for space-constrained designs. The 5V supply voltage and ceramic SMD package make it suitable for industrial applications. Consider the tri-state feature if bus sharing or power-down modes are necessary. Verify that the 25% stability tolerance is acceptable compared to higher precision alternatives in the CPPFX series.

Oscillators Part Context

This part belongs to the CPPFX series of field-programmable blank oscillators from Cardinal Components Inc. These devices allow end-users to program the frequency on-site, providing flexibility for prototype development and small-batch production. The series offers various package styles and output types, including CMOS and TTL, to accommodate diverse electronic design needs.

Oscillators Replacement Considerations

Direct substitutes within the same series include other CPPFX models with compatible package dimensions and voltage levels. For example, CPPFXC7L-A7BR-40.0000TS shares the same physical footprint but differs in frequency and voltage specifications. Always verify pinout compatibility and electrical parameters before substitution.
