CBTU04083 is an 8-to-4 differential channel multiplexer/demultiplexer switch. The CBTU04083 can switch four differential signals to one of two locations. Using a design technique, NXP has minimized the impedance of the switch such that the attenuation observed through the switch is negligible, and also minimized the channel‑to‑channel skew as well as channel‑to‑channel crosstalk, as required by the high‑speed serial interface. CBTU04083 allows expansion of existing high speed ports for extremely low power.
