描述 Description

CBTL02043A/B is a 2 differential channel, 2-to-1 multiplexer/demultiplexer switch forUSB 3.1, PCI Express Generation 3, or other high-speed serial interface applications. TheCBTL02043A/B can switch two differential signals to one of two locations. Using a uniquedesign technique, NXP has minimized the impedance of the switch such that theattenuation observed through the switch is negligible, and also minimized thechannel-to-channel skew as well as channel-to-channel crosstalk, as required by thehigh-speed serial interface. CBTL02043A/B allows expansion of existing high-speed portsfor extremely low power.
The device's pinouts are optimized to match different application layouts. CBTL02043Ahas input and output pins on the opposite of the package, and is suitable for edgeconnector(s) with different signal sources on the motherboard. CBTL02043B has outputson both sides of the package, and the device can be placed between two connectors tomultiplex differential signals from a controller. Please refer to Section 8 for layoutexamples.
