AM62P: the DPI interface

h p

Part Number: AM62P

Hi TI Experts,

We want to output YUV DATA to external CVBS Encoder by using AM62P DPI Interface, I saw the two LSBs are ignored and only bits[9-2] are effectively for BT.656 Mode, and the four LSBs are ignored and only bits[9-2]、bits[19-12] are effectively for BT.1120_16-bit Mode in TRM.

We want to know the following questons,

1.Does the AM62P support the Y,C divided mode when outputing YUV data(like below pictures)?

2.Does the data line of AM62P must follow the reference connneted method(only bits [9-2] are effectively used in BT.656_8-bit mode and only bits [19-12] are effectively used in BT.656_16-bit mode)? My understand is belowm, is right?

Hi,

Q1. I am not sure what you are asking about? It's either RGB or YUV and for YUV, it's only BT656 or BT1120.

Q2. Yes, your understand is correct.

Hi Expert,

---Actually, I want to confirm whether the AM62P DPI interface bits [9-2] are used for Outputing Y Data and bits [19-12] are used for Outputing C Data in BT.1120 mode?

And in BT.656 mode, only bits [9-2] can be used, and can only the YC composite Data be output ?

Hi Expert,

Thanks for your reply;

Does the AM62P support the two outputing(one for serializer, another for Encoder)from the DPI interface in the same time?

If support, which DATA line be used? and what the data type of two outputing? two bt.656? one bt.656, one RGB, or others?

Hi,

From DPI interface we can only output either RGB or YUV.
