3 Description

The TS3USBA225 is a 2-channel single-pole triple-throw (SP3T) multiplexer that supports USB 2.0 High-Speed (480 Mbps) signals in all 3 differential channels. The first two high-speed differential channels also support Mobile High Definition Link (MHL) signaling with resolution and video frame rates up to 720p, 60 fps and 1080i, 30 fps. The remaining differential channel can also be used as an audio switch that is designed to allow analog audio signals to swing negatively. This configuration allows the system designer to use a common connector for audio and USB 2.0 or MHL data.

The TS3USBA225 has a VCC range of 2.7 V to 5.0 V with the capability to pass true-ground audio signals down to –1.8 V. The device also supports a power-down mode that can be enabled when both SEL1 and SEL2 controls are low to minimize current consumption when no signal is transmitting. The TS3USBA225 also features internal shunt resistors on the audio path to reduce clicks and pops that may be heard when the audio switches are selected.
