Integrated Device Technology 19-output DB1900Z Compliant Buffer 9ZX21901BKLF

The 9ZX21901B is a version of the Intel DB1900Z Differential Buffer with an ajdustable external feedback path allowing the user to eliminate trace delays from their design. It is suitable for PCIe Gen3 or QPI applications. The part is backwards compatible to PCIe Gen1 and Gen2. The device maintains low drift for critical QPI applications. In bypass mode, the IDT9ZX21901 can provide outputs up to 400MHz. See the 9ZX21901C for a fixed external feedback path.
