dear sir
l use the TFP401 to achieve the HDMI to RGB change ,below is my schematic, u_sill1161 is TFP401 module board, U8 is TFP401 module schematic , when i
change the RXC_P RXC_N to 75M, the ODCK is 150M, when l change the RXC_P RXC_N to 50M, the ODCK is still 150M, the output image is fine ,but ODCK
output is always 150M, what`s wrong with my setting ?the internal PLL of TFP401didn`t work now, can you help to resolve it ? I didn`t use i2c; I change the resolution of HDMI source;
my HDMI source is PC ; l confirmed the frequency with the oscilloscope
