CDCE925PWR

Clock Generators, PLLs, Frequency Synthesizers Overview

The CDCE925PWR is a programmable PLL clock generator manufactured by Texas Instruments, housed in a 16-TSSOP surface-mount package. It operates on a single 1.7V to 1.9V supply and supports LVCMOS input and output logic levels. The device accepts crystal or LVCMOS inputs with a maximum frequency of 160 MHz and generates up to five outputs at frequencies reaching 230 MHz. It features an integrated VCXO control function for frequency pulling within ±150ppm. The component functions across an industrial temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Programmable architecture supporting multiple pre-configured settings via hardware pins
• Integrated voltage-controlled crystal oscillator (VCXO) capability for precise frequency adjustment
• Supports both crystal and LVCMOS signal inputs for flexible system integration

Clock Generators, PLLs, Frequency Synthesizers Applications

• Clock synthesis and jitter cleaning in digital communication systems
• Frequency generation for high-speed data converters and processors
• System timing solutions requiring low-power operation

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the revision level matches the design requirements. Cross-reference the datasheet version to validate all electrical parameters before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single PLL solution is required to generate multiple clock outputs from a single reference source. Ensure the application voltage remains within the 1.7V to 1.9V range. Verify that the required output count does not exceed five channels and that the LVCMOS output drive strength meets the load requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CDCE925 family of clock synthesizers. It serves as a lower-channel alternative to devices like the CDCE937, which offers seven outputs. The PWR suffix indicates tape-and-reel packaging, distinguishing it from tube-packaged variants such as the CDCE925PW.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The CDCE925PW is a compatible variant offering identical electrical specifications but utilizes tube packaging instead of tape-and-reel. Designers must verify footprint compatibility if switching between these packaging options.
