GENERAL DESCRIPTION
The ADV7282/ADV7282-M are versatile one-chip, multiformat
video decoders. The ADV7282/ADV7282-M 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 ADV7282 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 ADV7282-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 ADV7282/ADV7282-M accept
single-ended, pseudo differential, and fully differential signals.
The ADV7282/ADV7282-M contain a deinterlacer (I2P con-
verter) and short to battery detection capability with two STB
diagnostic pins. The ADV7282 provides four analog inputs.
The ADV7282-M provides six analog inputs and three general-
purpose outputs.
The ADV7282/ADV7282-M are programmed via a 2-wire, serial
bidirectional port (I2C compatible) and is fabricated in a 1.8 V
CMOS process. The ADV7282/ADV7282-M are provided in
space-saving, RoHS compliant LFCSP surface-mount packages.
The ADV7282/ADV7282-M are rated over the −40°C to +105°C
temperature range. This makes the ADV7282/ADV7282-M
ideal for automotive applications.

1 The Absolute Maximum Ratings assumes that DGND pins and the exposed
pad of the ADV7282/ADV7282-M are connected together to a common
ground plane (GND). This is part of the recommended layout scheme. See
PCB Layout Recommendations section for more information. The Absolute
Maximum Ratings are stated in relation to this common ground plane.
2 MVDD applies to the ADV7282-M only.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
This device is a high performance integrated circuit with an ESD
rating of <2 kV, and it is ESD sensitive. Proper precautions must
be taken for handling and assembly.

THERMAL RESISTANCE
The thermal resistance values in Table 8 are specified for the
device soldered onto a 4-layer printed circuit board (PCB) with
a common ground plane and with the exposed pad of the device
connected to DGND. The values in Table 8 are maximum values.

REFLOW SOLDER
The ADV7282/ADV7282-M is a Pb-free, environmentally
friendly product. It is manufactured using the most up-to-date
materials and processes. The coating on the leads of each device
is 100% pure Sn electroplate. The device is suitable for Pb-free
applications and can withstand surface-mount soldering at up
to 255°C (±5°C).
In addition, the ADV7282/ADV7282-M is backward-
compatible with conventional SnPb soldering processes. This
means that the electroplated Sn coating can be soldered with
Sn/Pb solder pastes at conventional reflow temperatures of
220°C to 235°C.
