Hi all,
I am using ADV7393, ADV7123, ADV7182 in the following manner
Case 1: ADV7393 -> ADV7182 loop back
Giving PAL interlaced format to AD7393 which analog output is loopbacked to ADV7182 analog input
Reading status registers of ADV7182
0x10 = 0x48 (AD_RESULT[2:0] always PAL B/PAL G/PAL H/PAL I/PAL D)
0x13 = 0x4C (bit[6]: '1' -> interlaced video detected, bit[4]: '0' -> free run mode inactive, bit[2]: '1' -> SD_OP_50Hz bit always 1)
Case 2: ADV7123 -> ADV7182 loop back
Giving PAL interlaced format to AD7123 which analog output is loopbacked to ADV7182 analog input
Reading status registers of ADV7182
0x10 = 0xC9 (AD_RESULT[2:0] always PAL B/PAL G/PAL H/PAL I/PAL D)
0x13 = 0x0D (bit[6]: '0' -> interlaced video not detected, bit[4]: '0' -> free run mode inactive, bit[2]: '1' -> SD_OP_50Hz bit always 1)
NOTE: Giving PAL interlaced video in both cases and reading ADV7182 status register post loopback.it is giving interlace video detected only in case 1 and interlace video not detected in case 2 but it should detect in both cases.
Can anyone will help on this issue??
