1 The 8-bit digital input/output port is only available when the DVDDIO supply is between 3.14 V and 3.46 V.
2 Guaranteed by lab characterization.
3 Typical current consumption values are recorded with nominal voltage supply levels (including DVDDIO = 3.3 V), Philips test pattern, and at room temperature.
4 Maximum current consumption values are recorded with maximum rated voltage supply levels (including DVDDIO = 3.46 V), MoireX video pattern for analog inputs,
pseudorandom test pattern for digital inputs, and at worst-case temperature.
5 Typical power-down current consumption values are recorded with nominal voltage supply levels (including DVDDIO = 3.3 V) at room temperature.
ANALOG VIDEO SPECIFICATIONS
AVDD = 1.71 V to 1.89 V, DVDD = 1.71 V to 1.89 V, PVDD = 1.71 V to 1.89 V, MVDD = 1.71 V to 1.89 V, CVDD = 1.71 V to 1.89 V,
DVDDIO = 3.14 V to 3.46 V, and TVDD = 3.14 V to 3.46 V, specified at operating temperature range, unless otherwise noted.

1 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 ADV7481 to switch from one analog input (single ended or differential) to another, for example, switching from AIN1 to AIN2.
