Description

The TMUX646 is an optimized 10-channel (5 differential) single-pole, double-throw bi-directional switch for use in high speed applications. The TMUX646 is designed to facilitate multiple MIPI compliant devices to connect to a single CSI/DSI, C-PHY/D-PHY module. The device also supports SATA, SAS, MIPI DSI/CSI, LVDS, RGMII, DDR and Ethernet interfaces.

The device has a bandwidth of 6 GHz, low channel-to-channel skew with little signal degradation, and wide margins to compensate for layout losses. The device’s low current consumption meets the needs of low power applications, including mobile phones and other personal electronics.
