DS90UB948-Q1: Block the 948 LVDS output

Hi Fery,

please see register 0x28 from UB948 d/s, it can disable the video data while enable the control signal.

What is your GPIO direction, from serializer to deserializer? thanks.

best regards,

Steven

Hi Steven,

Thanks for your reply, I will try with 0x28 register.

The GPIO direction is from SER to DESER, is the direction matters? How about the GPIO direction from DESER to SER if I disable the video output at DESER side?

Thanks.

for forward channel (from ser to deser), both GPIO and video are mapped into the serial link. from deser to ser, the GPIO is communicated by back channel. you can check the FPD-Link university training in my.ti.com. thanks.

best regards,
Steven
