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.
