CBTL02043ABQ,115

CBTL02043ABQ115 is a 2-different channel, 2-to-1 multiplexer/demultiplexer switch for USB 3.1, PCI Express Generation 3, or other high-speed serial interface applications. The CBTL02043B can switch two 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, and also minimized the channel-to-channel skew as well as channel-to-channel crosstalk, as required by the high-speed serial interface. CBTL02043B allows the expansion of existing high-speed ports for extremely low power. The device's pinouts are optimized to match different application layouts. CBTL02043B has outputs on both sides of the package, and the device can be placed between two connectors to multiplex differential signals from a controller. The application includes routing of high-speed differential signals with low signal attenuation, PCIe Gen3, DisplayPort 1.2, USB 3.1, SATA 6 Gbit/s.
