CBTL04082A; CBTL04082B 3.3 V, 4 differential channel, 2 : 1 multiplexer/demultiplexer switch for PCI Express Gen2 Rev. 1 — 28 February 2011 Product data sheet 1. General description 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 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. CBTL04082A/B allows expansion of existing high speed ports for extremely low power.
