Part Number: TS3DV642-Q1

Hi

Please help TS3DV642A0RUAR circuit confirmation,cause the CLK Switch only has I2C as a working connection, I'm wondering if this will have any impact.

    Hi Kevin,

    Can you elaborate on what you mean by the CLK switch only having I2C as a working connection?

    As far as your schematic goes, everything seems to look correct so far with the correct decoupling capacitors and resistors being utilized.

    Best regards,

    Hi 

    We are concerned about a potential bandwidth limitation issue since the DSI CLK is connected to the switch IC's I2C pins. Please help confirm if this configuration is completely okay. Thanks!

    Hi Kevin,

    The TS3DV642-Q1 supports differential bandwidths of -3dB from DC up to 5.8GHz so there should not be any bandwidth issues.

    Since you are using it for a DSI based application, I would recommend connecting the DSI CLK+ signal to the switch ICs HPD pin and the DSI CLK- signal to the CEC pin as shown in the datasheet's systems examples for DSI switching below.

    Best regards,

    Yonathan
