4-channel 2×2 crossbar switch handles 8G PCIe

The PI3PCIE3242 is a differential exchange switch featuring pass-through pinout. It supports one full PCI Express lane 2×2 operating at up to 8.0 Gbits/s. With the select control input low, Port A connects to B, and port C connects to D for an 8-channel differential pass-though. When select is high, Port A connects to D, and Port B connects to C. The arrangement is perfect for type C data connector reversal. 

The device exhibits crosstalk of less than -29 dB at 2.5 GHz and insertion loss is just 1.1 dB. Supply voltage is 3.3 V, ESD tolerance is 2 kV HBM, and it comes in a TQFN30 2.5 x 4.5 mm package.
