CPPT7-LT56T

Programmable Oscillators Overview

The CPPT7-LT56T is a programmable crystal oscillator manufactured by Cardinal Components Inc. It operates within a frequency range of 1 MHz to 100 MHz and utilizes TTL output logic levels. The device functions on a 3.3V supply voltage and includes enable/disable control capabilities. It features a frequency stability of ±100ppm and is housed in a compact 4-SMD, No Lead package suitable for surface mount applications.

Programmable Oscillators Feature Summary

• Dual-field programmability allows for custom frequency generation tailored to specific design requirements.
• Integrated enable and disable functionality provides power management flexibility during operation.
• Sealed ceramic construction ensures reliable performance across standard industrial temperature ranges.

Programmable Oscillators Applications

• Consumer electronics requiring PAL to NTSC video standard conversion
• Modem systems needing real-time switching between transmit and receive frequencies
• Industrial equipment requiring precise clock synchronization

Programmable Oscillators Procurement Notes

Verify the exact frequency configuration required for your application before ordering, as this is a programmable component. Confirm that the TTL output level matches your receiving circuit's input specifications. Ensure the 3.3V supply voltage aligns with your system's power rails. Check the lead time availability through authorized distributors, as stock levels may vary.

Programmable Oscillators Selection Notes

Select this model when a fixed-frequency oscillator does not meet specific timing needs. The ±100ppm stability is suitable for general digital communication interfaces. Consider the 4-SMD package size for space-constrained PCB layouts. Verify that the TTL output swing is compatible with downstream logic gates without additional buffering.

Programmable Oscillators Part Context

This component belongs to Cardinal Components' FIPO series of dual field-programmable blank oscillators. These devices are designed to provide sealed, finished custom oscillators with flexible frequency selection options. The series supports various output types and voltage levels to accommodate diverse electronic design requirements.

Programmable Oscillators Replacement Considerations

The CPPC7-LT56T serves as a CMOS output variant of this part number. Both share identical packaging and electrical characteristics except for the output logic family. Ensure the receiving circuitry supports CMOS levels if substituting with the CPPC7-LT56T model.
