CPPT7-HT7PP

Programmable Oscillators Overview

The CPPT7-HT7PP is a field-programmable crystal oscillator manufactured by Cardinal Components Inc. It operates within a frequency range of 1 MHz to 133 MHz and utilizes TTL output logic. The device supports a supply voltage of 5V and features a standby mode for power management. Frequency stability is specified at ±50 ppm. The component is housed in a 4-SMD, no-lead ceramic package with dimensions of 7.0mm x 5.0mm x 1.90mm. It is RoHS compliant and designed for surface-mount installation.

Programmable Oscillators Feature Summary

• Field programmable architecture allowing custom frequency configuration via Digi-Key ordering process
• Integrated standby function to reduce power consumption during inactive periods
• TTL output interface compatible with standard digital logic circuits
• RoHS compliant construction using lead-free materials

Programmable Oscillators Applications

• Clock generation for digital communication systems
• Timing reference for microprocessor-based embedded devices
• Synchronization sources for data acquisition equipment

Programmable Oscillators Procurement Notes

Verify the specific operating frequency requirement before placing orders, as this model requires programming. Confirm that the system design accommodates the 5V supply voltage and TTL output levels. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions. Check for any specific environmental temperature constraints relative to the stated operating range.

Programmable Oscillators Selection Notes

Select this component when a precise, customizable clock signal is needed without maintaining multiple stock frequencies. The TTL output simplifies integration into legacy or standard logic designs compared to CMOS alternatives. Consider the ±50 ppm stability requirement against system timing tolerance needs. Evaluate the standby feature if power efficiency is critical for the application environment.

Programmable Oscillators Part Context

This part belongs to the CPP series of field-programmable oscillators from Cardinal Components. These devices allow users to specify exact frequencies at the time of order, reducing inventory complexity. The CPPT7 variant specifically denotes a full-size ceramic package with TTL outputs, distinguishing it from half-size or CMOS versions within the same product family.

Programmable Oscillators Replacement Considerations

Direct substitutes include other CPPT7 series models with matching TTL outputs and similar package styles, such as CPPT7-HT0PP or CPPT7-HT5RP, provided their respective frequency stabilities (±50ppm or ±25ppm) meet system requirements. Verify that any replacement maintains the 5V supply voltage and 1MHz-133MHz operational range.
