GENERAL DESCRIPTION The ADV611/ADV612 are low cost, single chip, dedicated function, all-digital-CMOS-VLSI devices capable of supporting visually loss-less to 7500:1 real-time compression and decompression of CCIR-601 digital video at very high image quality
levels. The chips integrate glueless video and host interfaces with on-chip SRAM to permit low part count, system level implementations suitable for a broad range of applications. The ADV611/ADV612 are 100% bitstream compatible with the ADV601. The ADV611/ADV612 comes in a 120-lead LQFP package.
The ADV611/ADV612 are video encoders/decoders optimized for closed circuit TV (CCTV) applications. With the ADV611/...
