The ADV7180 is a 10-bit 4× oversampling SDTV video decoder from Analog Devices. It supports global NTSC/PAL/SECAM color demodulation and integrates AGC, 5-line adaptive comb filters, CTI/DNR video enhancement, adaptive digital line length tracking (ADLLT™), signal processing and enhanced FIFO management to give it mini-TBC functionality. The ADV7180 also has macrovision® copy protection detection, NTSC/PAL/SECAM autodetection, 8-bit ITU-R BT.656 YCrCb 4:2:2 output and HS, VS, FIELD1. It also has four general-outputs (GPO)2, a full-featured VBI data slicer, and a programmable peripheral clock generator (PCLK).
The ADV7180 video decoder from Analog Devices converts analog baseband television signals (NTSC, PAL, SECAM) from composite, S‑video, or component sources into a digital 8‑bit ITU‑R BT.656 4:2:2 output. It features a 10‑bit ADC, adaptive digital line length tracking, macrovision detection, and integrated AGC.
The device is offered in two Pb‑free packages—a 40‑lead LFCSP and a 64‑lead LQFP—providing four general‑purpose outputs, a 2‑wire I²C‑compatible serial interface, and low‑power modes for portable applications.
| Resolution (Each ADC) | 10 Bits |
|---|---|
| Number of video input channels | 3 |
| General‑purpose outputs (GPO) | 4 |
| Analog supply voltage | 1.71‑1.89 V |
It automatically detects and converts NTSC, PAL and SECAM standards from composite, S‑video, and component inputs.
The decoder provides three video input channels for CVBS (composite), Y/C (S‑video), and YPrPb (component).
The device outputs an 8‑bit ITU‑R BT.656 YCrCb 4:2:2 video stream.
