ADV7183B Rev. B is a multi-format SDTV video decoder from Analog Devices that supports NTSC-(J, M, 4.43), PAL-(B/D/G/H/I/M/N), and SECAM formats. The decoder integrates three 54 MHz, 10-bit ADCs and uses a single 27 MHz crystal clock locking. It also has Adaptive Digital Line Length Tracking (ADLLT™), signal processing, and enhanced FIFO management for mini-TBC functionality. Additionally, the decoder has five line adaptive comb filters, proprietary architecture for locking to VCRs and tuners, subcarrier frequency lock and status information output, integrated AGC with adaptive peak white mode, Macrovision® copy protection detection, chroma transient improvement (CTI), and digital noise reduction (DNR) functions.
The ADV7183B is a single‑chip, multiformat video decoder that automatically detects and converts NTSC, PAL, and SECAM standards from composite, S‑Video, and component sources into a digital ITU‑R BT.656 format. It integrates three 10‑bit ADCs, a 12‑channel input mux, and offers adaptive digital line‑length tracking, comb filtering, and macrovision detection.
Designed for a wide range of applications such as DVD recorders, video projectors, set‑top boxes, security cameras, and professional broadcast equipment, the device provides flexible digital output interfaces, low power consumption, and extensive video control features like brightness, contrast, hue, and saturation adjustments.
