MIPI Switches

Introduction

TI's portfolio of signal switches include several 6 GHz bandwidth devices that can support high-speed signal standards such as Mobile Industry Processor Interface (MIPI). These devices come in various channel counts and package options which enables designers to easily scale their system's video throughput and form factor.

The following diagrams show that multiple high-speed signal standards (C-PHY, D-PHY, and so forth) can be supported with a single device. Because these MIPI branded devices are low capacitance passive FET switches, many other high data rate protocols can be supported. Some examples include: LVDS, RGMII, LAN, DDR4, Ethernet, and so forth.

Each high bandwidth multiplexer includes s-parameter models and eye diagram comparisons for easy signal integrity simulation analysis.

The figures below show the comparison between a 6 Gbps signal passing through a low capacitance signal switch like the TMUX646 compared to a through path trace.
