CBTL02043A/B from NXP is a 2 differential channel, 2-to-1 multiplexer/demultiplexer switch for PCI Express Generation 3 (Gen3), or other high-speed serial interface applications. The CBTL02043A/B can switch two differential signals to one of two locations.
Using a unique design technique, NXP has minimised the impedance of the switch such that the attenuation observed through the switch is negligible, and also minimised 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.
