CBTL04083A/CBTL04083B
3.3 V, 4 differential channel, 2 : 1 multiplexer/demultiplexer switch for PCI Express Gen3
Rev. 4.1 — 27 July 2020
Product data sheet
1 General description
CBTL04083A/B is a 4 differential channel, 2-to-1 multiplexer/demultiplexer switch for PCI Express Generation 3 (Gen3) applications. The CBTL04083A/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 channelto-channel crosstalk, as required by the high-speed serial interface. CBTL04083A/B allows expansion of existing high speed ports for extremely low power.
