ADV202 概要
A JPEG2000 video codec is a hardware engine that encodes and decodes images using the wavelet-based JPEG2000 Part 1 standard. Unlike block-based JPEG, JPEG2000 employs a discrete wavelet transform followed by entropy coding to produce scalable, high-quality compressed streams. In a hardware codec such as the ADV202, the wavelet transform engine, entropy codecs, memory controller, and control processor are integrated on-chip, eliminating the need for a host DSP or external compressor in many systems. This is important for bandwidth-limited video links because one chip can compress 720p video or large still-frame imagery into a JPEG2000 stream and decompress it on the receive side.
Key features include a dedicated video port with glueless connection to common digital video standards such as 720p, plus programmable framing and validation signals for other high-speed synchronous pixel formats. The entropy codecs support all features of JPEG2000 Part 1 except the optional Maxshift ROI. Patented SURF (Spatial Ultra-efficient Recursive Filtering) technology enables low-power, low-cost implementation. Internally, the ADV202 contains a wavelet transform engine, three entropy codecs, an on-board memory system, and an embedded RISC processor that manages bitstream syntax and host commands.
From a system perspective, the ADV202 is a complete JPEG2000 compression/decompression solution. The tile engine accepts rectangular arrays of pixel samples, allowing trade-off between memory usage and image size. Because codec operation is tile-based, extremely large still images can be processed in manageable sections, while video can be streamed tile-by-tile. The embedded RISC processor handles host interfaces and entropy codec coordination, reducing external control complexity. Although the ADV202 is no longer recommended for new designs (NRND), its architecture remains the basis of the ADV212, the manufacturer-specified drop-in replacement, which adds JTAG/BSDL and cuts power by up to 50%.
Typical applications include broadcast and professional video systems, medical imaging and diagnostic capture, security and surveillance recording, aerospace and UAV payload compression, industrial machine vision, and remote-sensing image archival. For each application, the ADV202's combination of glueless video input, tile-based JPEG2000 Part 1 processing, and single-chip integration reduces BOM size compared with DSP-plus-software implementations. Designers migrating to the ADV212 retain these system benefits because the footprint and functionality are equivalent.
Design consideration: because the ADV202 is NRND, a new layout should target the ADV212. Confirm core and I/O supply voltages, maximum clock, power dissipation, and BGA ball map from the official 40-page datasheet before producing a footprint. Verify legacy firmware command compatibility when swapping an ADV202 for an ADV212 in an existing system.

設計ノート
The ADV202 requires multiple power supplies: core and I/O. Ensure proper decoupling with capacitors on all power lines, as noted in the SparkFun community post. The ADV212 consumes up to 50% less power, so for new designs, consider using the ADV212 to reduce thermal and power budget.
The ADV202 is a 144-ball BGA with a 1.4"x1.4" package. Ensure the PCB layout follows the manufacturer's recommended footprint and routing guidelines. Use a 4-layer or more board with solid ground plane. Verify the ball map from the datasheet before designing the footprint.
Since the ADV202 is NRND, avoid using it in new designs. If you must use it, verify availability and lead times. For legacy designs, when replacing with the ADV212, test firmware command compatibility, as the commands may differ. Refer to the Analog Devices EngineerZone discussion for guidance.
