Micrel MDB1900ZB
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). The MDB1900ZB works in conjunction with a CK410B+, CK509B or CK420BQ clock synthesizer to provide reference clocks to multiple agents.| Part No. | MDB1900ZB |
