if AT11 and AR9 can be used as DM8168 VGA H/V SYNC pins

I notice that DM8168 PG2.0 will support VGA H/V SYNC pins.Following is the mapping for HS and VS pins: HS -- AR5/AT9/AR8; VS -- AL5/AP9/AL9.

My questions are below items

1. if it means that only AR5/AT9/AR8 can be used as VGA HS. but AT11 and AR9 can not be used as VGA HS though AT11 and AR9 can pinmux as vout[0]_hsync?

2. if it has time delay between HS, VS pins and RGB signal. are their same module or different module?

Hello,

The decision to use the VOUT[0]_AVID pin (pin AR8) instead of the VOUT[0]_HSYNC pins (AT11 and AM9) was based on device layout. The pins come from the same module.

hi， MarcPyne

I have the same requirement to use hdvenc_A in discrete H/V sync mode o PG2.0 for VGA cable connection. how to do that? is there any sample code for it?

Hello,

Please refer to the HDVPSS section of the latest datasheet for details on how to use these DAC sync pins.
