●GENERAL DESCRIPTION
●The ADV7181B integrated video decoder automatically detects and converts a standard analog baseband television signal compatible with worldwide standards NTSC, PAL, and SECAM into 4:2:2 component video data-compatible with 16-/8-bit CCIR601/CCIR656.
●The advanced and highly flexible digital output interface enables performance video decoding and conversion in line locked clock-based systems. This makes the device ideally suited for a broad range of applications with diverse analog video characteristics, including tape based sources, broadcast sources, security/surveillance cameras, and professional systems.
●FEATURES
●Multiformat video decoder supports NTSC-(M, J, 4.43), PAL-(B/D/G/H/I/M/N), SECAM
●Integrates three 54 MHz, 9-bit ADCs
●Clocked from a single 27 MHz crystal
●Line-locked clock-compatible (LLC)
●Adaptive Digital Line Length Tracking (ADLLT™), signal processing, and enhanced FIFO management give mini TBC functionality
●5-line adaptive comb filters
●Proprietary architecture for locking to weak, noisy, and unstable video sources such as VCRs and tuners
●Subcarrier frequency lock and status information output
●Integrated AGC with adaptive peak white mode
