Si53119-A03A 19-OUTPUT PCIE GEN-3 BUFFER

The Si53119-A03A is a 19-output, low-power HCSL differential clock buffer that meets all of the performance requirements of the Intel DB1200ZL specification. To reduce board space and bill of material cost, the device fully integrates all external resistors, supporting 85  transmission lines. It is optimized for distributing reference clocks for Intel® Qui.
