ADV601LCJSTRL

Overview

The ADV601LCJSTRL is an ultralow cost, single-chip video codec manufactured by Analog Devices Inc. It supports real-time compression and decompression of CCIR-601 digital video at high image quality levels. The device features a generic 16-bit or 32-bit host interface with a 512-position, 32-bit wide FIFO for compressed video buffering. It accepts component digital video through the Video Interface and outputs a compressed bit stream through the Host Interface in Encode Mode. In Decode Mode, it accepts a compressed bit stream via the Host Interface and outputs component digital video through the Video Interface. The chip integrates glueless video and host interfaces with on-chip SRAM to permit low part count system implementations.

Feature Summary

• Supports field-independent compression using sub-band coding architecture
• Integrates wavelet kernel, programmable quantizer, and entropy coders
• Provides precise compressed bit rate control via adaptive bin width calculation
• Includes on-chip transform buffer to eliminate need for extremely fast external memories

Applications

• PC Video Editing
• Remote CCTV Surveillance
• Digital Camcorders
• Wireless Video Systems
• TV Instant Replay

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Confirm availability status as older components may be discontinued or subject to long lead times. Ensure the source document matches the exact part number to avoid confusion with similar models in the ADV601 family.

Selection Notes

Select this component for applications requiring visually loss-less to moderate compression ratios of interlaced digital video. Evaluate the system's ability to handle the required pixel rates and field sizes supported by the CCIR-601 standard. Consider the host processor's capability to manage the 16/32-bit interface and calculate bin widths for constant bit rate operation if needed.

Part Context

The ADV601LC is part of the ADV601 family of video codecs. It is designed to be 100% bitstream compatible with the original ADV601 model while offering an ultralow cost solution. The device is optimized for real-time processing of interlaced digital video formats such as PAL and NTSC.

Replacement Considerations

The ADV601LC is 100% bitstream compatible with the ADV601. Verify pinout and electrical specifications before substituting other video codecs from different manufacturers.
