These specifications apply to all CVBS input types, as well as to single-ended and differential CVBS inputs.

2

Guaranteed by lab characterization.

3

Guaranteed by design.

4

The CMRR of this circuit design is critically dependent on the external resistor matching its inputs. This measurement was performed with 0.1% tolerant resistors, a

common-mode voltage of 1 V, and a common-mode frequency of 10 kHz.

5

The time it takes the ADV7482 to switch from one analog input (single ended or differential) to another, for example, switching from AIN1 to AIN2.
