ADV7179BCPZ

Overview

The ADV7179BCPZ is a single-chip digital video encoder that converts CCIR-601 4:2:2 8-bit component video data into analog baseband signals compatible with NTSC and PAL standards. It features three high-quality 10-bit video DACs, an on-board voltage reference, and a super sub-alias filter (SSAF) for enhanced luminance response. The device operates on a single 2.8 V or 3.3 V supply and accepts a 27 MHz clock for standard operation, or specific frequencies for square pixel modes. It supports multiple output formats including composite, S-video, YPbPr, and RGB via programmable simultaneous outputs.

Feature Summary

• Converts digital CCIR-656 4:2:2 YCrCb data to analog TV signals using 10-bit DACs and SSAF technology
• Supports multistandard video outputs including composite, S-video, component, and SCART RGB
• Includes advanced power management with normal, low power, and sleep modes
• Features integrated timing generation, closed captioning support, and teletext insertion ports

Applications

• Portable video applications
• Mobile phones
• Digital still cameras

Procurement Notes

Verify the exact revision level of the datasheet before design implementation, as specifications may be subject to change without notice. Confirm that the LFCSP package exposed pad is properly soldered to the PCB ground plane to ensure thermal dissipation and mechanical stability during assembly.

Selection Notes

Select this component when a compact solution is required to encode digital component video into analog baseband formats. Ensure the system provides a stable 27 MHz clock input for standard operation or appropriate frequencies for square pixel modes. Verify that the application requires the specific output combinations supported by the three internal DACs.

Part Context

This part belongs to the ADV7174/ADV7179 family of chip-scale video encoders manufactured by Analog Devices Inc. It shares architectural similarities with the ADV7174, though the ADV7179 lacks the Macrovision anti-copy feature found in the ADV7174 variant. Both devices utilize the same 40-lead LFCSP package and pinout configuration.

Replacement Considerations

The ADV7174BCPZ is a functional substitute within the same family, offering identical encoding capabilities but including Macrovision 7.1 copy protection support.
