JPEG 2000 Video Codec
ADV212
FEATURES
Complete single-chip JPEG 2000 compression and
decompression solution for video and still images
Identical in pinout and footprint to the ADV202 and
supports all the functionality of the ADV202
Power reduction of at least 30% compared with ADV202
JTAG/boundary scan support
Patented SURF® (spatial ultraefficient recursive filtering)
technology enables low power, low cost wavelet-based
compression
Supports both 9/7 and 5/3 wavelet transforms with up to
6 levels of transform
Video interface directly supporting ITU-R BT.656,
SMPTE 125M PAL/NTSC, SMPTE 274M, SMPTE 293M
(525p), and ITU-R BT.1358 (625p), or any video format with
a maximum input rate of 65 MSPS for irreversible mode or
40 MSPS for reversible mode

Flexible, asynchronous SRAM-style host interface allows glue-
less connection to most 16-/32-bit microcontrollers and ASICs
2.5 V or 3.3 V input/output and 1.5 V core supply
12 mm × 12 mm, 121-ball CSPBGA with a speed grade of
115 MHz, or 13 mm × 13 mm, 144-ball CSPBGA with a
speed grade of 150 MHz
GENERAL DESCRIPTION
The ADV212 is a single-chip JPEG 2000 codec targeted for
video and high bandwidth image compression applications that
can benefit from the enhanced quality and features provided by
the JPEG 2000 (J2K)—ISO/IEC15444-1 image compression
standard. The part implements the computationally intensive
operations of the JPEG 2000 image compression standard and
provides fully compliant code-stream generation for most
applications.
The dedicated video port of the ADV212 provides glueless con-
nection to common digital video standards such as ITU-R BT.656,
SMPTE 125M, SMPTE 293M (525p), ITU-R BT.1358 (625p),
SMPTE 274M (1080i), or SMPTE 296M (720p). A variety of
other high speed, synchronous pixel and video formats can also
be supported by using the programmable framing and
validation signals.
The ADV212 is an upgrade version of the ADV202 that is
identical in pinout and footprint. It supports all the functionality
of the ADV202 and has the following additional options:
• JTAG/boundary scan support
• Power reduction of at least 30% compared with the
ADV202
