PI2USB4122ZHEX

Analog Switches - Special Purpose Overview

The PI2USB4122ZHEX is a 4-to-1 differential channel multiplexer/demultiplexer switch designed for USB 3.0 applications supporting data rates up to 5.0 Gbps. It operates on a single supply voltage of 1.8V with a tolerance of +/-10%. The device features a maximum bit-to-bit skew of 7ps and a channel-to-channel skew of 35ps. Electrical characteristics include a typical quiescent current of 300µA, an off-isolation of -25dB at 2.5GHz, and crosstalk of -40dB at 2.5GHz. The bandwidth is rated at 2.6GHz (-3dB), with a differential insertion loss of -3.0dB at the same frequency. It is housed in a 42-contact TQFN package.
