CBTU04083 High-Speed Multiplexer/Switch

NXP's CBTU04083 can switch four differential signals to one of two locations

NXP's 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 unique design technique, NXP has minimized the impedance of the switch such that the attenuation observed through the switch is negligible. NXP has also minimized the channel-to-channel skew as well as channel-to-channel crosstalk as required by the high-speed serial interface. The CBTU04083 allows the expansion of existing high speed ports for extremely low power.

The CBTU04083 high-speed switch also supports other emerging standards including 6Gbps SATA/SAS and DisplayPort v1.2 HBR2 at 5.4Gbps. By supporting these standards, the NXP CBTU04083 multiplexer/switch makes it straightforward for system designers to address the demanding performance and signal integrity requirements of future high-end computing products.
