Single-lane, 2 differential channel SPDT bus switch ICs – TC7PCI3212MT and TC7PCI3215MT – support PCIe Gen3 (8 Gbps) and achieve bandwidth characteristics of 11.5 GHz at -3 dB. These characteristics enable high-speed transmission with minimized signal degradation. Also, bandwidth minimizes attenuation of signal amplitude by inserting switch and can pass through GHz high-speed differential signals. Configurations promote optimal arrangements of PCIe slots, connectors, and switches.
