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 ADV7281/ADV7281-M/ADV7281-MA 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 ADV7281/ADV7281-M/ADV7281-MA to switch from one analog input (single-ended or differential) to another, for
