USB Type-C High performance Crossbar Switch IC
Rev. 2 — 1 August 2016
Product data sheet
1. 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.
