TEXAS INSTRUMENTS CDCV857B CDCV857BI handbook
The CDCV857B is a high-performance, low-skew, low-jitter zero delay buffer designed to distribute a differential clock input pair to 10 differential pairs of clock outputs and one differential pair of feedback clock outputs. It operates from dual 2.5-V supplies and is compatible with spread spectrum clocking to reduce EMI. The device enters a low-power mode when the input frequency falls below a suggested detection frequency or when the PWRDWN pin is low.

Questions answered in these manuals
Does the device support spread spectrum clocking?
Yes, the CDCV857B is able to track spread spectrum clocking for reduced EMI.
What happens when the PWRDWN pin is low?
When PWRDWN is low, all outputs are disabled to a high-impedance state and the PLL is shut down to a low-power mode.
What is the operating frequency range of the CDCV857A?
The device operates from 60 to 180 MHz.
