CBTL04082A/B is an 8-to-4 bidirectional differential channel multiplexer/demultiplexer switch for PCI Express Generation 2 (Gen2) applications. The CBTL04082A/B can switch four 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. CBTL04082A/B allows expansion of existing high speed ports for extremely low power.
The devices’ pinouts are optimized to match different application layouts. CBTL04082A 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. CBTL04082B 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.
