3.3 V, 4 differential channel, 2 : 1 multiplexer/demultiplexer

switch for PCI Express Gen3

Rev. 4 — 25 June 2012

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.

2. Features and benefits
