GENERAL DESCRIPTION
The ADV7283 is a versatile one-chip, multiformat video
decoder that automatically detects standard analog baseband
video signals compatible with worldwide NTSC, PAL, and
SECAM standards in the form of composite, S-Video, and
component video.
The ADV7283 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 six analog video inputs of the ADV7283 can accept single-
ended, pseudo differential, and fully differential signals.
The ADV7283 contains a deinterlacer (I2P converter) that
allows the device to output video in a progressive format.
The ADV7283 is programmed via a 2-wire, serial bidirectional
port (I2C compatible) and is fabricated in a 1.8 V CMOS
process.
The ADV7283 is provided in a space-saving LFCSP surface-
mount, RoHS-compliant package.
The ADV7283 is available in an automotive grade rated over the
−40°C to +105°C temperature range, as well as a −40°C to +85°C
temperature range, making the device ideal for both automotive
and industrial applications.

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 Fast switch speed is the time required for the ADV7283 to switch from one analog input (single-ended or differential) to another, for example, switching from AIN1 to AIN2.
