Overview
CBTL08GP053 is an 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 x 3.25 mm, 0.5 mm pitch.
