产品概述
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.Because it is based on the PLL circuitry, the CDCVF2505 requires a stabilization time to
achieve phase lock of the feedback signal to the reference signal. This stabilization is required
following power up and application of a fixed-frequency, fixed-phase signal at CLKIN, and following
any changes to the PLL reference.
