TMDS442: AUTO SWITCHING USING HOT PLUG PINS.

penchala prasad

Part Number: TMDS442

Hai,

Can anyone tell me how to do auto switching (i.e; Displaying the active source connected to the switcher) using hot plug pins in TMDS442. Please provide me any hardware connection diagram, or any data related to the issue.

Thanks & Regards,

Prasad.

The TMDS442 does not do auto switching. The only way to change sources and outputs is to change it either through the GPIO pins or through I2C.

Page 22 of the data sheet shows how to change the source with the GPIO and "Table 3. TMDS442 Sink Port Register Bit Decoder (continued)" shows how to use I2C to change the source.
