CDCE937QPWRQ1

Clock Generators, PLLs, Frequency Synthesizers Overview

The CDCE937QPWRQ1 is an automotive-grade programmable clock synthesizer and jitter cleaner manufactured by Texas Instruments. It integrates three phase-locked loops (PLLs) to support VCXO clock synthesis applications. The device operates within a supply voltage range of 2.3 V to 3.6 V and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a TSSOP-20 surface-mount format, it is designed for high-reliability environments requiring precise timing control.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 Grade requirements for your target automotive application zone. Cross-reference the datasheet revision date with your design timeline to account for any potential product change notifications or lifecycle updates.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple independent clock domains are required from a single source. The triple PLL architecture allows for distinct frequency outputs without external dividers. Consider the TSSOP-20 footprint constraints during PCB layout. Verify input reference frequency ranges match the available crystal or oscillator sources in the system design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CDCE937-Q1 family of automotive clock generators. It shares functional similarities with other TI automotive clock synthesizers but is distinguished by its triple-PLL configuration. The 'Q1' suffix denotes automotive qualification, while 'PWR' indicates the TSSOP-20 package style.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other members of the CDCE937-Q1 family with compatible pinouts. Verify electrical parameters such as output drive strength and power consumption before swapping. Non-pin-compatible alternatives may require schematic redesign.
