FEATURES Complete single-chip JPEG2000 compression and decompression solution for video and still images Patented SURF® (spatial ultra-efficient recursive filtering) technology enables low power and low cost wavelet- based compression Supports both 9/7 and 5/3 wavelet transforms with up to 6 levels of transform Programmable tile/image size with widths up to 2048 pixels in 3-component 4:2:2 interleaved mode, and up to 4096 pixels in single-component mode Maximum tile/image width: 4096 pixels Video interface directly supporting ITU.R-BT656, SMPTE125M PAL/ NTSC, SMPTE274M, SMPTE293M (525p), ITU.R-BT1358 (625p) or any video format with a maximum input rate of 65 MSPS for irreversible mode or 40 MSPS for reversible mode Two or more ADV202s can be combined to support full- frame SMPTE274M HDTV (1080i) or SMPTE296M (720p) Flexible asynchronous SRAM-style host interface allows glueless connection to most 16-/32-bit microcontrollers and ASICs 2.5 V to 3.3 V I/O and 1.5 V core supply 12 mm × 12 mm 121-lead CSPBGA, speed grade 115 MHz, or 13 mm × 13 mm 144-lead CSPBGA, speed grade 135 MHz, or 13 mm × 13 mm 144-lead CSPBGA, speed grade 150 MHz APPLICATIONS Networked video and image distribution systems Wireless video and image distribution Image archival/retrieval Digital CCTV and surveillance systems Digital cinema systems Professional video editing and recording Digital still cameras Digital camcorders GENERAL DESCRIPTION The ADV202 is a single-chip JPEG2000 codec targeted for video and high bandwidth image compression applications that can benefit from the enhanced quality and feature set provided by the JPEG2000 (J2K)—ISO/IEC15444-1 image compression standard. The part implements the computationally intensive operations of the JPEG2000 image compression standard as well as providing fully compliant code-stream generation for most applications. The ADV202’s dedicated video port provides glueless connection to common digital video standards such as ITU.R-BT656, SMPTE125M, SMPTE293M (525p), ITU.R-BT1358 (625p), SMPTE274M (1080i), or SMPTE296M (720p). A variety of other high speed, synchronous pixel and video formats can also be sup- ported using the programmable framing and validation signals.
