CDCE813QPWRDN

Clock Generators, PLLs, Frequency Synthesizers Overview

The CDCE813QPWRDN is an automotive-grade programmable clock synthesizer and jitter cleaner from Texas Instruments. It features a single PLL capable of generating up to three LVCMOS outputs with frequencies up to 230 MHz. The device operates on a 1.8 V core supply and supports separate 2.5 V or 3.3 V output supplies (VDDOUT). Input options include external crystals (8–32 MHz) or LVCMOS signals up to 160 MHz. It includes integrated VCXO functionality, spread-spectrum clocking for EMI reduction, and nonvolatile EEPROM storage for configuration settings.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'PWRDN' against the manufacturer's official orderable addendum to confirm package type, tape-and-reel specifications, and regional availability. Ensure that the automotive qualification grade matches the project requirements before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single-input, multi-output clock solution is required for automotive environments. It is suitable for designs needing flexible input sources and independent output voltage levels. Verify that the maximum output frequency of 230 MHz meets the target system timing requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CDCE813-Q1 family of modular PLL-based clock synthesizers. It shares functional similarities with other members like the CDCEL913 but is specifically optimized for automotive reliability standards. The device eliminates the need for external crystal oscillators by integrating the necessary oscillator circuitry.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same automotive-qualified family include the CDCE813R02-Q1, which differs primarily in the default hardware enable function of the S0 pin. Other family members such as the CDCE913 or CDCE925 offer different output counts or PLL configurations.
