CPPT7-LT7PP

Programmable Oscillators Overview

The CPPT7-LT7PP 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. The device is designed for surface-mount installation in a 4-SMD, no-lead package with physical dimensions of 5mm x 7mm. It functions at a supply voltage of 3.3V and maintains a frequency stability of ±50 ppm. The component supports an operating temperature range from -40°C to +85°C and features a standby mode capability.

Programmable Oscillators Feature Summary

• Field-programmable architecture allowing custom frequency configuration
• Integrated tri-state functionality for enable and disable control
• Low-power standby mode operation
• RoHS compliant ceramic surface-mount construction

Programmable Oscillators Applications

• General-purpose clock signal generation in digital systems
• Timing reference for microprocessors and microcontrollers
• Data communication interface synchronization
• Embedded system clock sources requiring specific frequency customization

Programmable Oscillators Procurement Notes

Verify the exact programmed frequency against project requirements before ordering, as this is a field-programmable device. Confirm that the TTL output voltage levels are compatible with the receiving logic inputs. Ensure the 3.3V supply voltage matches the system design specifications. Check for any specific programming tool requirements if on-site programming is planned. Validate the operating temperature range meets environmental conditions.

Programmable Oscillators Selection Notes

Select this component when a precise, non-standard frequency is required between 1 MHz and 100 MHz. Choose the TTL output variant if the downstream circuitry expects standard TTL logic levels. Consider the 3.3V supply requirement and ensure power budgeting aligns with system constraints. The 4-SMD package is suitable for space-constrained PCB layouts. Verify the ±50 ppm stability is sufficient for the application's timing tolerance needs.

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, offering flexibility compared to fixed-frequency crystals. The series includes various output types and voltage options, with the CPPT7-LT7PP specifically providing TTL output at 3.3V.

Programmable Oscillators Replacement Considerations

Direct substitutes include other parts from the Cardinal Components CPP series with matching TTL output and 3.3V operation, such as the CPPT7-HT7PP or CPPT7-BP-FREQ1TS, provided the frequency and stability requirements are met. Cross-model comparison should focus on package size, pinout compatibility, and electrical specifications.
