TS3DV642-Q1: MIPI-DSI BUS SWITCH and RGMII BUS SWITCH

Part Number: TS3DV642-Q1


Tool/software:

Hi,

Our customer is considering using this IC for the following two purposes. Can we use it?

Application 1: MIPI-DSI BUS SWITCH

Two different LCDs are connected to the output destination of the SoC MIPI-DSI (CLK 1Lane + Data 4Lane), so we would like to switch between them.

→ P.19 Figure 9-8. Mipi DPHY based DSI switching. Would this be a problem if we use the configuration?

Application 2: RGMII BUS SWITCH
Two different Ethernet PHYs are connected to the output destination of the SoC RGMII (12bit in the table below), so we would like to switch between them.
→ IO voltage 1.8V, clock frequency 125MHz.

→ Can we switch by using all 12bits, SCL, SDA, D0± to D3±, HPD, CEC?
(SCL, SDA, HPD, CEC can also be used as Mux for high-speed signals.)

Best regards,

Hiroshi

    Yes, TS3DV642-Q1 12-Channel 1:2 MUX/DEMUX is recommended for General Purpose High-Speed Signal Switching.  

    With its recommended signal swing on the data lines be within 0-5.5 V, it will support the RGMII 1.8V signaling. For the SCL/SDA, HPD, and CEC, these paths are not different than the other signal paths in the device but are labeled differently to match up with the signals used in HDMI applications.

    Thanks
