3.3 V, 2 differential channel, 2 : 1 multiplexer/demultiplexer switch

CBTL02043A/B is a 2 differential channel, 2-to-1 multiplexer/demultiplexer switch for

USB 3.1, PCI Express Generation 3, or other high-speed serial interface applications. The

CBTL02043A/B can switch two 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. CBTL02043A/B allows expansion of existing high-speed ports

for extremely low power.

The device's pinouts are optimized to match different application layouts. CBTL02043A

has input and output pins on the opposite of the package, and is suitable for edge

connector(s) with different signal sources on the motherboard. 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. Please refer to Section 8 for layout

examples.
