The MDB1900ZC is a true zero delay buffer with a fully integrated, high-performance, low-power, and low-phase noise programmable PLL.
The MDB1900ZC is capable of distributing the reference clocks for PCIe (Gen1/Gen2/Gen3), SATA, ESI, SAS, SMI, and Intel® Quickpath Interconnect (QPI). The MDB1900ZC works in conjunction with a CK410B+, CK509B, or CK420BQ clock synthesizer to provide reference clocks to multiple agents.
The MDB1900ZC is designed for Intel’s DB1900Z specification with the exception that the zero delay buffer feedback path is inside the IC and does not need to be built onto the PCB.
