The CDCVF25081 is a high performance, low skew, low jitter, phased-locked loop clock driver. It uses a PLL to precisely align, in both frequency and phase, the output clocks to the input clock signal. The outputs are divided into 2 banks for a total of 8 buffered CLKIN outputs. The device automatically puts the outputs to a low state when no CLKIN signal is present (power down mode).
The S1 and S2 pins allow selection between PLL or bypassed PLL outputs. When left open, the outputs are disabled to a logic low state.
The part supports a fail-safe function. The device further incorporates an input hysteresis which prevents random oscillation of the outputs in the absence of an input signal.
The device operates in 3.3V supply environment and is characterized from –40°C to 85°C (ambient temperature).
