TMDS181: has a solution for stabiliy with 1080p 59.96fps?

Hi,

Can you try the following I2C command and see if it helps?

<aardvark>

<configure i2c="1" spi="1" gpio="0" tpower="1" pullups="0"/>

<i2c_bitrate khz="100"/>

<i2c_write addr="0x5e" count="1" radix="16">09 06</i2c_write> <sleep ms="10"/>   -> Set lane and polarity swap, disable automatically power down base on HDP_SNK

<i2c_write addr="0x5e" count="1" radix="16">FF 01</i2c_write> <sleep ms="10"/> -> Select Page 1 registers

<i2c_write addr="0x5e" count="1" radix="16">01 01</i2c_write> <sleep ms="10"/> -> Charge pump enable. PLL mode, used with the HDMI

<i2c_write addr="0x5e" count="1" radix="16">02 3F</i2c_write> <sleep ms="10"/>  -> Charge pump current control. 7F max charge pump current setting, may need to sweep the value

<i2c_write addr="0x5e" count="1" radix="16">00 03</i2c_write> <sleep ms="10"/> -> Bit 0 -> Enable PLL and Bit 1 -> Enable bandgap

<i2c_write addr="0x5e" count="1" radix="16">0B 33</i2c_write> <sleep ms="10"/> -> Bit [1:0] Loop filter resistance, try setting to 30h and 31h

<i2c_write addr="0x5e" count="1" radix="16">A1 02</i2c_write> <sleep ms="10"/> -> Bit 1 -> Override control for Page 1 register 0x0B, 0x0C, and 0x0D. The register 0x0B write will take effect

<i2c_write addr="0x5e" count="1" radix="16">A4 03</i2c_write> <sleep ms="10"/> -> Bit 1 -> Page 1 Register 0x01 override control. Bit 0 -> Page 1 Register 0x00 override control

<i2c_write addr="0x5e" count="1" radix="16">FF 00</i2c_write> <sleep ms="10"/> -> Select Page 0 registers

</aardvark>

Thanks
