Does ADV7280 support input 525p/60Hz YPrPb, output 8Bit 422 HS/VS SDR mode ?

Hello all,

 

We have the evaluation board of the ADV7280 connected to:

a YPrPb(525p/60Hz) camera on its Ain1,2,3 input

a BT601 parallel CSI port of Allwinner A10 SOC on its digital camera input

 

 

we do test the following two scripts:

1). by modify YPbPr script(##YPrPb AUTODETECT##:YPrPb In Ain1,2,3, YPrPb Out:):

42 0F 00 ; Exit Power Down Mode [ADV7280 Writes Begin]

42 00 0C ; INSEL = YPrPb, Y=Ain1, Pb=Ain2, Pr=Ain3

42 0E 80 ; ADI Required Write

42 04 3D ; 0x04[3].TIME_OE=1 enable hs vs output ----add----

42 6A 03 ; pin_hs=de mode                        ----add----

42 6B 91 ; pin_vs=vsync mode                     ----add----

42 80 51 ; ADI Required Write

42 81 51 ; ADI Required Write

56 00 1C ; Power up Encoder

56 01 00 ; SD only mode

56 80 10 ; SSAF Luma filter enabled, NTSC mode

56 82 C9 ; Step control on, pixel data valid, pedestal on, PrPb SSAF on, YPrPb out.

56 87 20 ; PAL/NTSC autodetect mode enabled

56 88 00 ; 8 bit input enabled [Encoder Writes finished]

2). by modify YPbPr script(##YPrPb Interlaced to Progressive##:I2P - YPrPb In Ain1,2,3, 480p EAV/SAV, YPrPb Out:):

42 0F 00 ; Exit Power Down Mode [ADV7280 Writes Begin]

42 00 0C ; INSEL = YPrPb, Y=Ain1, Pb=Ain2, Pr=Ain3

42 0E 80 ; ADI Required Write

56 01 70 ; ED at 54MHz input

Question 1

  Does ADV7280 support input 525p/60Hz YPrPb, output 8Bit 422 HS/VS SDR mode(ED-SDR at 54MHz) ?

 

Question 2

  In ADV7280_CUST-VER.4.5.txt script file, there is no reference script for support input 525p/60Hz YPrPb and output 8Bit 422 HS/VS SDR mode,

  Offer script of the ADV7280 support input 525p/60Hz YPrPb, output 8Bit 422 HS/VS SDR mode(ED-SDR at 54MHz) ?

 

   I believe there should be some method to config customer to solve this problem, or if there are some other approach.

 

 

Thanking you

With best regards and wishes
