ADV7174/ADV7179 is a chip-scale PAL/NTSC video encoder that supports ITU-R1 BT601/BT656 YCrCb to PAL/NTSC video encoding, with high-quality 10-bit video DACs, SSAF™ (super sub-alias filter) and advanced power management features.
The ADV7174/ADV7179 are high-quality 10-bit video DACs designed as a Chip Scale Package (CSP) for portable video applications such as mobile phones. These devices function as ITU-R BT.601/BT.656 YCrCb to PAL or NTSC video encoders, featuring programmable subcarrier frequency and phase, SSAF filtering, and complete on-chip video timing generation.
The document provides comprehensive specifications for 2.8 V and 3.3 V operation, including static performance metrics like resolution (10 bits), integral nonlinearity (+/- 3.0 LSB), and differential nonlinearity (guaranteed monotonic). It also covers detailed timing requirements for the MPU port, clock control, pixel ports, and teletext interfaces.
| Resolution (Each DAC) | 10 Bits |
|---|---|
| Integral Nonlinearity | +/- 3.0 LSB |
| Differential Nonlinearity | Guaranteed monotonic +/- 1 LSB |
| Output Compliance, Voc | 0 to 14 V |
| Clock Frequency (ferock) | 27 MHz |
The device operates from -40°C to +85°C at 3.3 V and from -20°C to +85°C at 2.8 V.
The device requires a single 27 MHz clock with x2 oversampling.
Each DAC provides 10-bit resolution.
