1 Guaranteed by characterization.
2 Typical current consumption values are measured with nominal voltage supply levels and an SMPTE bar test pattern.
3 All specifications apply when the I2P core is activated, unless otherwise stated.
VIDEO SPECIFICATIONS
AVDD, DVDD, PVDD, and MVDD = 1.71 V to 1.89 V, DVDDIO = 2.97 V to 3.63 V, specified at operating temperature range, unless otherwise noted.
Specifications guaranteed by characterization. Note that MVDD only applies to the ADV7282-M.

1 These specifications apply for all CVBS input types (NTSC, PAL, and SECAM), as well as for single-ended and differential CVBS inputs.
2 The CMRR of this circuit design is critically dependent on the external resistor matching on the circuit inputs (see the Input Networks section). The CMRR measurement
was performed with 0.1% tolerant resistors, a common-mode voltage of 1 V, and a common-mode frequency of 10 kHz.
3 Autodetection switch speed is the time required for the ADV7282/ADV7282-M to detect which video format is present at its input, for example, PAL I or NTSC M.
4 Fast switch speed is the time required for the ADV7282/ADV7282-M to switch from one analog input (single-ended or differential) to another, for example, switching from
AIN1 to AIN2.
