3 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.
