Overview
The CDCVF2505DR, produced by Texas Instruments, is a high-performance, low-skew, low-jitter phase-lock loop (PLL) clock driver. This device is designed to precisely align the output clocks to the input clock signal in both frequency and phase, making it ideal for synchronous DRAM and general-purpose applications. It operates at a single 3.3-V supply voltage and features integrated series-damping resistors and an on-chip RC PLL loop filter, which eliminates the need for external components. The CDCVF2505DR is characterized for operation from –40°C to 85°C and is available in 8-pin TSSOP and 8-pin SOIC packages.
