CDC421A106RGET

Clock Generators, PLLs, Frequency Synthesizers Overview

The CDC421A106RGET is a fully integrated fixed-frequency low-jitter crystal oscillator manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 3.6 V and supports an output frequency of up to 106.25 MHz. The device features one LVPECL output and accepts Crystal or LVCMOS input levels. Packaged in a 24-VQFN (4x4 mm) exposed pad format, it functions reliably across an industrial temperature range from -40°C to +85°C. Designed for surface-mount installation, this clock synthesizer integrates essential oscillation components to provide precise timing signals with minimal external requirements.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix RGET corresponds to the 24-VQFN package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the ordering quantity aligns with standard factory pack sizes to avoid partial reel handling issues during procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed 106.25 MHz clock signal is required with low jitter performance. Compare against other CDC421A variants if different frequencies or output formats are needed. Ensure the system power supply remains within the 3 V to 3.6 V range and that thermal management accommodates the VQFN package constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CDC421A106 series of low-jitter clock generators. It shares the same package and electrical characteristics as related models like the CDC421A100RGET, differing primarily in the programmed output frequency. The series is designed for applications requiring stable, clean clock signals without the complexity of programmable PLL synthesizers.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other CDC421A family members with compatible packages, such as CDC421A100RGET, provided the frequency difference is acceptable. Verify pinout compatibility and electrical specifications before substituting.
