Overview
The ADV601LCJSTZRL, produced by Analog Devices Inc., is an ultralow-cost, single-chip, dedicated function, all-digital CMOS VLSI device. It is designed to support visually loss-less to 350:1 real-time compression and decompression of CCIR-601 digital video at very high image quality levels. This codec is optimized for real-time compression and decompression of interlaced digital video, making it suitable for a broad range of applications. The ADV601LC integrates glueless video and host interfaces with on-chip SRAM, allowing for low part count system-level implementations.
