Programmable Oscillators Procurement Notes

Verify the specific target frequency required for your application during the ordering process, as this component is programmed upon request. Confirm that the 4-SMD no-lead package dimensions align with your PCB footprint design. Ensure the 3.3V supply rail meets the current requirements specified in the datasheet. Check for any specific handling instructions regarding ESD sensitivity associated with surface-mount programmable oscillators.

Programmable Oscillators Selection Notes

Select this model when a fixed-frequency oscillator does not meet system timing requirements and a custom frequency between 1 MHz and 100 MHz is necessary. Consider the TTL output compatibility with downstream logic circuits. Evaluate the ±50ppm stability against system jitter tolerance. Verify that the -40°C to +85°C operating range covers the environmental conditions of the final assembly.

Programmable Oscillators Part Context

This part belongs to the CPPT7/LT7 series of programmable oscillators from Cardinal Components Inc. These devices are designed to replace multiple fixed-frequency crystals and oscillators, reducing inventory complexity. The LT7 suffix typically indicates specific performance characteristics or pinout configurations within the broader product family.

Programmable Oscillators Replacement Considerations

Direct replacements must match the 4-SMD no-lead package and TTL output type. Verify that substitute parts support the same 1 MHz to 100 MHz programming range and ±50ppm stability. Ensure compatible 3.3V operation and identical thermal specifications.
