GENERAL DESCRIPTION

The ADV7280/ADV7280-M are versatile one-chip, multiformat

video decoders. The ADV7280/ADV7280-M automatically detect

standard analog baseband video signals compatible with worldwide

NTSC, PAL, and SECAM standards in the form of composite,

S-Video, and component video.

The ADV7280 converts the analog video signals into a YCrCb

4:2:2 video data stream that is compatible with the 8-bit ITU-R

BT.656 interface standard. The ADV7280-M converts the analog

video signals into an 8-bit YCrCb 4:2:2 video data stream that is

output over a mobile industry processor interface (MIPI®) CSI-2

interface.

The analog video inputs of the ADV7280/ADV7280-M accept

single-ended signals. The ADV7280 provides four analog inputs;

the ADV7280-M provides eight analog inputs. The ADV7280

and ADV7280-M support I2P conversion.

The ADV7280/ADV7280-M are programmed via a 2-wire,

serial bidirectional port (I

C compatible) and are fabricated in a

1.8 V CMOS process. The LFCSP package option makes these

decoders ideal for space-constrained portable applications.

These specifications apply for all CVBS input types (NTSC, PAL, and SECAM).

The CMRR of this circuit design is critically dependent on the external resistor matching on the circuit inputs (see the Input Network 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.

Autodetection switch speed is the time required for the ADV7280/ADV7280-M to detect which video format is present at its input, for example, PAL I or NTSC M.

Fast switch speed is the time required for the ADV7280/ADV7280-M to switch from one analog input to another, for example, switching from A

1 to A
