描述
The 9ZXL1230 is a small-footprint, low-power, 12-output differential buffer that meets all the performance requirements of the Intel DB1200ZL specification. It is pin-compatible to the 9ZX21200 while consuming over 50% less power. The 9ZXL1230 is backward compatible with PCIe Gen 1, Gen 2, and QPI 6.4GT/s specifications. A fixed, internal feedback path maintains low drift for critical QPI applications.
