This document provides a detailed introduction to the ADV7196A product, including its features, input and output formats, etc.
The ADV7196A is a triple high‑speed digital‑to‑analog video encoder on a single monolithic chip. It supports multiple input formats (YCrCb 4:2:2, 4:4:4 and RGB) and outputs YPrPb progressive‑scan, HDTV, and RGB signals, complying with standards such as SMPTE‑293M, ITU‑R BT.1358, EIA‑770 and RS‑170/RS‑343A.
The datasheet provides full electrical specifications, timing diagrams, pin configurations, absolute maximum ratings, and ordering information for the 52‑lead MQFP package, along with programmable features like sharpness filter, adaptive filter control, and macrovision.
| Resolution (Each DAC) | 11 Bits |
|---|---|
| Integral Nonlinearity | 1.5 LSB |
| Differential Nonlinearity | 0.9‑2.0 LSB |
| Output High Voltage (Vor) | 0.4 V |
| Output Low Voltage (Von) | 2.4 V |
| Full‑Scale Output Current – DAC A | 3.92‑4.56 mA |
| Full‑Scale Output Current – DAC B/C | 2.54‑3.11 mA |
| Power Supply | Single 3.3 V |
| Package | 52‑lead MQFP |
The device operates from a single 3.3 V power supply, with an optional external 1.235 V reference.
It outputs analog YPrPb progressive‑scan (EIA‑770.1, .2), YPrPb HDTV (EIA‑770.3), and RGB levels compliant to RS‑170 and RS‑343A.
In HDTV mode the device draws 51‑60 mA for 2× interpolation, or 40 mA for single interpolation.
