CDCVF2505PWR

Clock Generators, PLLs, Frequency Synthesizers Overview

The CDCVF2505PWR is a 3.3-V clock phase-locked loop (PLL) clock driver manufactured by Texas Instruments. It integrates a high-performance PLL with five low-skew, low-noise fanout buffers to provide simultaneous clock distribution and jitter attenuation. The device accepts a single-ended LVCMOS/LVTTL input signal and generates five differential PECL-compatible outputs. Designed for high-speed applications, it supports maximum output frequencies up to 650 MHz. The component operates within a supply voltage range of 3.135 V to 3.465 V and functions across an industrial temperature range from -40°C to +85°C. It is housed in a 20-pin TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'PW' corresponds to the 20-pin TSSOP package and 'R' indicates tape-and-reel packaging when sourcing. Confirm that the manufacturer documentation explicitly lists the CDCVF2505PWR variant to ensure compatibility with design specifications. Cross-reference the datasheet revision date to validate parameter accuracy against current production standards.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when both clock distribution and jitter reduction are required in a single package. It is suitable for designs needing differential PECL outputs driven by single-ended logic inputs. Ensure the application frequency does not exceed the 650 MHz limit and that the power supply constraints align with the specified 3.3-V nominal operation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CDCVF2505 belongs to Texas Instruments' family of 3.3-V clock drivers utilizing phase-locked loop technology. This series is engineered to replace discrete buffer and PLL combinations, reducing board space and complexity. The device addresses noise sensitivity in high-speed digital systems by cleaning input clock signals before distribution to multiple downstream components.
