Toshiba America Electronic Components Inc. has brought to market its single-lane, two differential channel single pole double throw (SPDT) bus switch ICs. According to the company, the TC7PCI3212MT and TC7PCI3215MT support PCI Express (PCIe) Gen3 (8Gb/s) and achieve wide bandwidth characteristics of 11.5GHz at -3dB.

The TC7PCI3212MT and TC7PCI3215MT join the previously announced TC7PCI3412MT and TC7PCI3415MT, which are intended for circuit design engineers working with third-generation PCIe or other high-speed interface applications (including USB 3.0 and SATA 3.0).


The wide bandwidth characteristics achieved by the bus switches make high-speed transmission with lower signal degradation possible. Wide bandwidth also reduces the attenuation of signal amplitude by inserting a switch, and can pass through GHz high-speed differential signals. The TC7PCI3212MT and TC7PCI3215MT have optimal configurations for arrangements of PCIe slots, connectors and switches on the motherboards of servers, desktop PCs, notebook PCs and PC peripheral devices.

The SPDT switches operate with a power-supply voltage range from 3V to 3.6V. The devices also boast low insertion loss of 1dB at VCC=3.3V, f=4GHz. In addition, the devices feature low switch terminal ON-capacitance of 1.5pF (typ.) at VCC=3.3V

Toshiba's SPDT switches are available with budgetary pricing starting at $0.50.
