This document introduces the ADV7190/ADV7191 video encoder from Analog Devices, which features six high-quality 10-bit digital-to-analog converters (DACs), multistandard video input and output, internal 54 MHz PLL, programmable video control including digital noise reduction, gamma correction, luma delay, chroma delay, etc. Additionally, the encoder supports various functions such as Luma SSAF, average brightness detection, Macrovision protection, CGMS, WSS, closed captioning support, etc.
The ADV7190/ADV7191 is a video encoder with six high‑quality 10‑bit DACs, supporting multiple video standards (NTSC‑M, NTSC‑J, PAL‑N, PAL‑M, PAL‑B/D/G/H/I, PAL‑60) and offering programmable video controls such as digital noise reduction, gamma correction, and macrovision. It operates from either 5 V or 3.3 V supplies and is available in a 64‑lead LQFP package.
The datasheet provides detailed static and dynamic performance specifications, timing characteristics for MPU, pixel and teletext ports, as well as package dimensions and pin configuration. It also lists recommended applications like DVD playback and PC multimedia systems.
