10-Bit, 4× Oversampled SDTV Video
Decoder with Differential Inputs
Data Sheet
ADV7282A
FEATURES
GENERAL DESCRIPTION
Worldwide NTSC/PAL/SECAM color demodulation support
One 10-bit ADC, 4× oversampling per channel for CVBS, Y/C,
and YPrPb modes
Analog video input channels with on-chip antialiasing filter
ADV7282A: up to 4 input channels
ADV7282A-M: up to 6 input channels
Video input support for CVBS (composite), S-Video (Y/C),
and YPrPb (component)
Fully differential, pseudo differential, and single-ended
CVBS video input support
The ADV7282A1 has the same pinout as and is software
compatible with the ADV7282 with the exception of a updated
IDENT code. The mobile industry processor interface (MIPI®)
model of the ADV7282A (ADV7282A-M) has the same pinout
as and is software compatible with the ADV7282-M with the
exception of an updated IDENT code.
All features, functionality, and specifications are shared by the
ADV7282A and the ADV7282A-M, unless otherwise noted.
The ADV7282A is a versatile one-chip, multiformat video
decoder that automatically detects standard analog baseband
video signals and converts them into YCrCb 4:2:2 component
video data streams.
NTSC/PAL/SECAM autodetection
STB diagnostics on 2 video inputs
Up to 4 V common-mode input range solution
Excellent common-mode noise rejection capabilities
5-line adaptive 2D comb filter and CTI video enhancement
Integrated AGC with adaptive peak white mode
Fast switching capability
Integrated I2P video output converter (deinterlacer)
ACE
The analog input of the ADV7282A features an input mux
(4-channel on ADV7282A, 6-channel on ADV7282A-M), a
single 10-bit analog-to-digital converter (ADC) and an on-chip
differential to single-ended converter to accommodate the
direct connection of differential, pseudo differential, or single-
ended CVBS without the need for external amplifier circuitry.
Downdither (8-bit to 6-bit)
The standard definition processor (SDP) in the ADV7282A
automatically detects PAL, NTSC and SECAM standards in the
form of composite, S-Video (Y/C) and component. The analog
video is converted into a 4:2:2 component video data stream
that is output either via an 8-bit ITU-R BT.656 standard-
compatible interface (ADV7282A) or via a MIPI CSI-2 Tx
(hereafter referred to as MIPI Tx) interface (ADV7282A-M).
The ADV7282A also feature a deinterlacer for interlaced to
progressive (I2P) conversion.
Rovi copy protection detection
8-bit ITU-R BT.656 YCrCb 4:2:2 output and HS, VS, or field
synchronization (ADV7282A)
MIPI CSI-2 output interface (ADV7282A-M only)
Full featured VBI data slicer with WST support
Power-down mode available
2-wire, I2C-compatible serial interface
Qualified for automotive applications
−40°C to +105°C temperature grade
The ADV7282A offers short to battery (STB) diagnostic sense
inputs and general-purpose outputs.
32-lead, 5 mm × 5 mm, RoHS compliant LFCSP
APPLICATIONS
The ADV7282A is provided in a space-saving LFCSP surface-
mount, RoHS compliant package. The ADV7282A is rated over
the −40°C to +105°C temperature range, making it ideal for
automotive applications.
The ADV7282A must be configured in accordance with the I2C
writes provided in the evaluation board script files available at
www.analog.com/ADV7282A.
