MDB1900ZB Datasheet (Micrel Semiconductor)

MDB1900ZB, Zero Delay Buffer

The MDB1900ZB is a true zero delay buffer with a fullyintegrated, high-performance, low-power, and low-phase noise programmable PLL.

The MDB1900ZB is capable of distributing the reference clocks for PCIe (Gen1/Gen2/Gen3), SATA, ESI, SAS, SMI and Intel® Quickpath Interconnect (QPI).
