CBTL01023
3.3 V, one differential channel, 2 : 1 multiplexer/demultiplexer
switch for PCI Express Gen3
Rev. 1 — 24 October 2011
Product data sheet
1. General description
CBTL01023 is a single differential channel, 2-to-1 multiplexer/demultiplexer switch for
PCI Express Generation 3 (Gen3), or other high-speed serial interface applications.
The CBTL01023 can switch one differential signal 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 crosstalk, as required by the high-speed serial interface.
CBTL01023 allows expansion of existing high speed ports for extremely low power.
