CDCVF25081PWRG4

Clock Generators, PLLs, Frequency Synthesizers Overview

The CDCVF25081PWRG4 is a zero-delay PLL clock multiplier manufactured by Texas Instruments. It accepts a single LVTTL input and provides eight LVTTL outputs with a 1:8 multiplication ratio. The device operates within a supply voltage range of 3V to 3.6V and supports maximum frequencies up to 133.3MHz. It is housed in a 16-TSSOP package with a width of 4.40mm. The component functions as a multiplier without internal dividers or bypass capabilities, designed for surface mount installation.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero-delay buffer architecture ensures minimal output skew relative to the input reference signal.
• Integrates a Phase-Locked Loop (PLL) circuit for precise frequency multiplication.
• Supports standard LVTTL logic levels for both input and output interfaces.

Clock Generators, PLLs, Frequency Synthesizers Applications

• Clock distribution in high-speed digital systems
• Frequency multiplication for processor and memory buses
• Signal buffering in telecommunications equipment

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the suffix 'G4' indicates compliance with specific environmental standards such as RoHS. Confirm the 'PW' package designation matches the required 16-TSSOP footprint. Ensure the manufacturer is identified as Texas Instruments to avoid counterfeit components. Check for lead-free soldering requirements compatible with assembly processes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a 1:8 clock multiplication ratio is required with LVTTL compatibility. Compare against the CDCVF25084 series if differential inputs or higher frequencies are needed. Verify that the 3V to 3.6V operating voltage aligns with the system power rails. Consider the TSSOP-16 package constraints for PCB layout density.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CDCVF2508x family of zero-delay clock multipliers from Texas Instruments. It shares architectural similarities with the IDT2308 series but utilizes TI's proprietary PLL technology. The device is functionally comparable to other members like the CDCVF25084, differing primarily in input/output configurations and maximum frequency specifications.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The IDT2308-1HPG is listed as an obsolete upgrade replacement. Verify pinout compatibility before substitution. Other potential alternatives include variants within the CDCVF2508x family, though specific electrical parameters must be matched.
