This document describes the features and characteristics of the ADV7174/ADV7179 chip scale PAL/NTSC video encoder, including ITU-R1 BT601/BT656 YCrCb to PAL/NTSC video encoder, high quality 10-bit video DACs, advanced power management features, etc.
The ADV7174 and ADV7179 are chip‑scale PAL/NTSC video encoders with advanced power‑management, 10‑bit DACs, and support for multiple video standards including NTSC, PAL‑N, PAL‑B/D/G/H/I, and more. The device integrates a digital synthesizer for color subcarrier generation, on‑chip video timing, and optional features such as CGMS, WSS, and teletext insertion.
The document lists electrical specifications for both 2.8 V and 3.3 V supply versions, timing diagrams for the MPU port and video data, pin configuration, register maps, and ordering information. Appendices describe optional functions such as copy‑generation management, wide‑screen signaling, and teletext support.
| Resolution (Each DAC) | 10 Bits |
|---|---|
| Input High Voltage (2.8 V version) | 1.6 V |
| Typical DAC Output Current | 35 mA |
The ADV7174 version operates from a 2.8 V supply.
Both devices are offered in a 40‑lead 6 mm × 6 mm LFCSP (lead‑frame chip‑scale package).
Each DAC can deliver up to about 35 mA into a 150 Ω load.
