ADV7619 support....

Hi !

 

I've a customer that need support/comment on their use of the ADV7619 :

*****************************************************************************************************************

What is the correct ADV7619 configuration to achieve the following behavior?

 

Source:

4k2k (29,97fps) YCbCr 4:2:2, 8bit/component, TMDS =
297MHz.

 

Output:

2x16 SDR, YCbCr 4:2:2,  LCC = 148,5Mhz.

 

The datasheets state that “2 x SDR 4:2:2 Interleaved mode 0” is not available when CP is bypassed, but for HDMI formats over 2.25Gbps the CP must be bypassed and 2x24 pass-through (interleaved?) should be used.

 

In the example scripts for configuring 4k2k the CP is not bypassed.

 

Looking at the example scripts for 4k2k, the following script has been constructed. The changed commands are marked with ----><----.

 

:03-02 4K2K YCbCr 422 In - 2x16-bit YCbCr 422 Out:

98 FF 80 ; I2C reset

98 F4 80 ; CEC

98 01 06 ; Prim_Mode =110b HDMI-GR (101b for HDMI-comp?)

98 02 F0 ; Auto CSC, YCbCr out, Set op_656 bit

 

---->98 03 94 ; 2x16 bit SDR 422 interleaved mode

98 05 28 ; AV Codes Off

4C C3 80 ; ADI Required Write

4C CF 03 ; ADI Required Write

68 C0 03 ; ADI Required write

 

---->68 00 09 ; Set HDMI Input Port B (BG_MEAS_PORT_SEL

End

 

Does this configuration look correct to you?
