ADV7183B 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), SECAM and other formats. It integrates three 54 MHz, 10-bit ADCs and supports unstable video sources such as VCRs and tuners.
The ADV7183B is a single‑chip multiformat video decoder that automatically detects and converts NTSC, PAL, and SECAM analog video signals (composite, S‑Video, component) into a digital ITU‑R BT.656 4:2:2 output. It integrates three 10‑bit ADCs, a 12‑channel input mux, and adaptive digital line‑length tracking to handle noisy or unstable sources such as VCRs and tuners.
Typical applications include DVD recorders, video projectors, set‑top boxes, security cameras, and professional broadcast equipment. The device offers programmable video controls, macrovision detection, VBI data recovery, and a low‑power 3.3 V CMOS process.
| ADC resolution | 10 bits |
|---|---|
| Analog input voltage range | 0.5 V to 1.6 V |
| Analog supply voltage | 3.3 V |
| Digital output format | ITU‑R BT.656 YCrCb 4:2:2 |
It supports NTSC (J, M, 4.43), PAL (B/D/G/H/I/M/N) and SECAM standards.
The recommended analog input video signal range is 0.5 V to 1.6 V.
It provides an ITU‑R BT.656 YCrCb 4:2:2 output with HS, VS, and FIELD signals.
The decoder uses three 54 MHz, 10‑bit analog‑to‑digital converters.
