The Renesas Electronics 9ZX21200 is a small-footprint 12-output differential buffer that meets all the performance requirements of the Intel DB1200Z specification. The 9ZX21200 is backwards compatible to PCIe Gen1 and Gen2 applications. A fixed, internal feedback path maintains low drift for critical QPI applications. In bypass mode, the 9ZX21200 can provide outputs up to 150MHz.
