The text in section 6.4 of the current ADV7604 hardware manual refers to SYNC 1-4 in Figure 12. But Figure 12 only shows SYNC 2-3.
Can you confirm that the Figure 12 diagram in the manual is correct?
Also if the RCB-Black colours of the Ain pins are supposed to route to the matching colours of ADC0-3, this also does not match the routing data in Table8 for the AIN_SEL[2:0] register. Can you clarify this please?
