The HD74CDC857 is a high-performance, low-skew, low-jitter, phase locked loop clock driver.

It is specifically designed for use with DDR (Double Data Rate) synchronous DRAMs.

Supports 100 MHz to 150 MHz operation range.
1.
Distributes one differential clock input pair to ten differential clock outputs pairs.
SSTL_2 (Stub Series Terminated Logic) differential inputs and LVCMOS reset (G) input.
Supports spread spectrum clock.
External feedback pins (FBIN, FBIN) are used to synchronize the outputs to the clock input.
Supports both 3.3 V/2.5V analog supply voltage (AV CC), and 2.5 V VDDQ.
No external RC.
