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
channel-to-channel crosstalk, as required by the high-speed serial interface.
CBTL04083A/B allows expansion of existing high speed ports for extremely low power.
The device's pin out are optimized to match different application layouts. CBTL04083A
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. CBTL04083B 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.
