PCA(PCIe Cable Adapter)，which is used to connect PCIe upstream slot with downstream target board by a PCIe x4 cable , supports the PCIe x4 & x1 mode. PCA card can provide programmable equalization, amplification, and de-emphasis for PCIe transceiver signal by using 8 select bits. It is also available to optimize performance over a variety of physical mediums by reducing Inter-symbol interference.
PCA is a PCIe cable adapter card which supports these features:
• Up to 5.0Gbps PCIe 2.0 Serial ReDriver
• PCIe x4 Gen 2
• Adjustable receiver equalization
• Adjustable transmitter amplitude and de-emphasis
- In the demonstration，the PCA functions as an adapter card between TR4 and PC.
