Switch ICs support transmission speeds up to PCIe Gen3

The devices are suitable for applications involving the switching between different high-speed controller ICs such as PCIe Gen3, USB 3.0 and SATA 3.0 or the multiplexing of a single controller IC to expand the number of available peripheral interfaces. Typically, this occurs in industrial and consumer PCs, as well as networking and storage applications.

The switch ICs achieve high bandwidth characteristics of 11.5GHz at -3dB. These characteristics reduce switch terminal capacitance, enabling high-speed transmission with lower signal degradation.

All inputs are equipped with protection circuits against static discharge. Operating across a power supply voltage range of 3.0-3.6V, the TC7PCI3212MT and TC7PCI3215MT feature a typical low ON-capacitance of CI/O of 1.5pF at VCC=3.3V, enabling the low insertion loss of -1dB at frequencies of 4GHz. This low insertion loss together with a crosstalk of -40dB, enable high performance during PCIe Gen3 compliance testing.

Rated for an operational temperature range of -40 to 85°C, the switch ICs are offered in an industry standard TQFN20 package. The devices vary only by pin arrangement, which have been designed to enable designers to specify chips that optimally fit existing PCB designs.
