ADV7281 10-Bit, 4× Oversampled SDTV Video Decoder Decoder with Differential Inputs

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 via a 2-wire, serial bidirectional port (I2C compatible) and are fabricated in a 1.8 V CMOS process. The LFCSP package option makes these decoders ideal for space-constrained portable applications.
