6-OUTPUT LOW-POWER HCSL BUFFER FOR PCIE GEN1-2-3 AND QPI
DATASHEET
9ZXL0651
General Description
The 9ZXL0651 is a low-power 6-output differential buffer that meets all the performance requirements of the Intel DB1200Z specification. It consumes 50% less power than standard HCSL devices and has internal terminations to allow direct connection to 85 ohm transmission lines. The 9ZXL0651 is backwards compatible to PCIe Gen1 and Gen2 and QPI 6.4GT/s specifications. A fixed, internal feedback path maintains low drift for critical QPI applications.
