CPPT7-HT56T

Programmable Oscillators Overview

The CPPT7-HT56T is a field-programmable TTL clock oscillator manufactured by Cardinal Components Inc. It operates within a frequency range of 1 MHz to 133 MHz and requires a 5V supply voltage. The device features a tri-state enable/disable function for power management. It utilizes a 4-SMD, no-lead ceramic package with dimensions of 7.0mm x 5.0mm x 1.7mm. Key electrical specifications include a maximum rise/fall time of 3.4 ns, an output load of 50 pF, and a frequency stability of ±100 ppm. The unit supports operation at temperatures up to 70 °C and is compliant with RoHS standards.

Programmable Oscillators Feature Summary

• Field programmable blank oscillator allowing on-the-fly frequency configuration using PG-3000 series instruments
• Integrated tri-state enable and disable functionality for system power control
• TTL output interface compatible with standard digital logic circuits
• Sealed ceramic surface-mount construction ensuring environmental durability

Programmable Oscillators Applications

• Consumer electronics requiring PAL to NTSC conversion via frequency switching
• Modem applications involving real-time transmit and receive frequency changes
• Embedded systems needing customizable clock signals for microcontrollers
• Industrial equipment requiring specific timing references for communication protocols

Programmable Oscillators Procurement Notes

Verify the exact frequency requirement against the 1 MHz to 133 MHz operational range before ordering. Confirm that the design includes support for the PG-3000 or PG-3100 programming instruments, as these are required for field configuration. Ensure the PCB footprint matches the 4-SMD no-lead specification. Check for RoHS compliance requirements if operating in regulated markets. Validate the 5V supply voltage compatibility with the target system's power rails.

Programmable Oscillators Selection Notes

Select this component when a custom frequency solution is needed without manufacturing lead times for fixed oscillators. The tri-state feature makes it suitable for designs requiring clock gating or low-power standby modes. Consider the ±100 ppm stability if precise timing is not critical. The TTL output level simplifies integration with legacy digital interfaces. Evaluate the physical size constraints against the 7.0mm x 5.0mm package dimensions.

Programmable Oscillators Part Context

This part belongs to the CPP series of field-programmable blank oscillators from Cardinal Components Inc. These devices allow users to program the output frequency after purchase, providing flexibility for prototype development and small-batch production. The series includes various output types and packages, with the HT56T specifically offering TTL outputs in a compact ceramic SMD form factor.

Programmable Oscillators Replacement Considerations

Direct replacements must match the TTL output type, 5V supply, and 4-SMD package. Verify that substitute parts support the same frequency range and tri-state functionality. Cross-reference pinouts to ensure compatibility with existing PCB layouts.
