1. General description
2. Features and benefits
CBTL02042A/B is a 2 differential channel, 2-to-1 multiplexer/demultiplexer switch for PCI
Express Generation 2 (Gen2), and other high-speed serial interface applications. The
CBTL02042A/B can switch two 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. CBTL02042A/B allows expansion of existing high speed ports
for extremely low power.
The device's pinouts are optimized to match different application layouts. CBTL02042A
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. CBTL02042B 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
examples.

... Function selection and shutdown function The CBTL02042A/B provides a shutdown function to minimize power consumption when the application is not active, but power to the CBTL02042A/B is provided. The XSD pin (active HIGH) places all channels in high-impedance state (non-conducting) while reducing current consumption to near-zero. When XSD pin is LOW, the device operates normally ...
