CDCV857BDGGG4 [Texas Instruments]

The CDCV857B is a high-performance, low-skew, low-jitter zero delay buffer that distributes a differential clock input pair (CLK, CLK) to 10 differential pairs of clock outputs (Y[0:9], Y[0:9]) and one differential pair of feedback clock outputs (FBOUT, FBOUT). It operates from dual 2.5-V supplies and features a PLL for zero-delay synchronization. The device enters a low-power mode when no input clock is applied or when PWRDWN is low, consuming <100 µA quiescent current. It supports spread spectrum clocking for EMI reduction and meets/exceeds DDR JEDEC specifications.
