Part Description

The CDCVF2505 is a high-performance, low-skew, low-jitter, phase-lock loop (PLL) clock driver. This device uses a PLL to precisely align the output clocks (1Y[0-3] and CLKOUT) to the input clock signal (CLKIN) in both frequency and phase. The CDCVF2505 operates at 3.3 V and also provides integrated series-damping resistors that make it ideal for driving point-to-point loads. One bank of five outputs provides low-skew, low-jitter copies of CLKIN. Output duty cycles are adjusted to 50 percent, independent of duty cycle at CLKIN. The device automatically goes into power-down mode when no input signal is applied to CLKIN. The loop filter for the PLLs is included on-chip. This minimizes the component count, space, and cost. The CDCVF2505 is characterized for operation from –40°C to 85°C.
