GENERAL DESCRIPTION

The ADV7281/ADV7281-M/ADV7281-MA are versatile

one-chip, multiformat video decoders. The ADV7281/

ADV7281-M/ADV7281-MA 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 ADV7281 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 ADV7281-M/ADV7281-MA convert 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 ADV7281/ADV7281-M/

ADV7281-MA accept single-ended, pseudo differential, and

fully differential signals. The ADV7281 provides four analog

inputs and two STB diagnostic pins. The ADV7281-M provides

six analog inputs, two STB diagnostic pins, and three general-

purpose outputs. The ADV7281-MA provides eight analog

inputs and three general-purpose outputs.

The ADV7281/ADV7281-M/ADV7281-MA are programmed

fabricated in a 1.8 V CMOS process. The LFCSP package option

makes these decoders ideal for space-constrained portable

applications.
