12-OUTPUT DIFFERENTIAL Z-BUFFER FOR PCIE GEN2/3 AND QPI 9ZX21201
General Description
The IDT9ZX21201 is a 12-output DB1200Z suitable for PCI-Express Gen3 or QPI applications. The part is backwards compatible to PCIe Gen1 and Gen2. A fixed external feedback maintains low drift for critical QPI applications. In bypass mode, the IDT9ZX21201 can provide outputs up to 150MHz.
Recommended Application
12-output PCIe Gen3/ QPI differential buffer for Romley and newer platforms
Key Specifications
