General description

CBTL08GP053 is a USB Type-C High Performance Crossbar Switch IC meant to be used

for Type-C connector interface high speed passive switching applications. It provides

switching of high speed differential signals that correspond to various interface standards:

USB3.1 (10 Gbps), DP1.3 (8.1 Gbps), PCI Express 3.0 (8 Gbps), etc. It supports switching

of single ended signals over Type-C interface. In addition, side band switching of AUX and

other dedicated signals for transport over SBU1 and SBU2.

It provides the I2C-bus interface for switch control, configuration and status update. It

operates from a single platform power supply VDD.

This IC is targeted for a wide range of platforms (PCs, tablets, convertibles, smart phones)

and PC accessories (e.g. docks, monitors, etc.) applications.

CBTL08GP053 is available in a small footprint package option: VFBGA40 4.75 mm 

3.25 mm, 0.5 mm pitch.
