GL9931B
產品簡述

GL9931 is a PCIe linear redriver which could improve the signal integrity via programmable input setting. It supports up to PCIe Gen3 (8Gbps) and backwards compatible with PCIe 2.0 & 1.0. The equalization, output swing and gain could be adjusted through I2C interface or pin-strapping setting. With GL9931, the PCB trace length could be extended and noise interference would be reduced which can increase the flexibility of PCB design. The target applications are networking, PC, Notebook, workstation and data center servers.

 

All available packages for GL9931 are listed in the following table.
