ADV7179WBCPZ

Overview

The ADV7179WBCPZ is a chip-scale PAL/NTSC video encoder that converts digital CCIR-601 4:2:2 YCrCb data into analog baseband television signals. It features high-quality 10-bit video DACs, an integrated SSAF™ filter, and advanced power management for single-supply 2.8 V or 3.3 V operation. The device supports multiple video standards including NTSC M, PAL N2, and PAL B/D/G/H/I/M/N/60. It accepts a 27 MHz clock for standard operation or specific frequencies for square pixel mode. Key capabilities include programmable luma/chroma filters, CGMS/WSS generation, closed captioning support, and a teletext insertion port. Output configurations include composite, S-video, RGB (SCART), and YPbPr.

Feature Summary

• Converts digital 4:2:2 component video to analog TV signals with studio-quality SSAF filtering
• Supports simultaneous composite and S-video or RGB/YPbPr outputs via programmable DAC control
• Integrates on-chip timing generator with main/subordinate operational modes
• Includes dedicated ports for teletext insertion and closed captioning data handling

Applications

• Portable video applications
• Mobile phones
• Digital still cameras

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range specifications. Ensure compatibility with system voltage requirements, as the device supports both 2.8 V and 3.3 V supplies with distinct operating ranges. Confirm automotive qualification status if required for the specific application environment.

Selection Notes

Select this model when a compact solution for converting digital component video to analog broadcast formats is needed. It is suitable for designs requiring low power consumption through sleep modes and flexible output configurations. Consider the ADV7174 variant if Macrovision copy protection functionality is explicitly required, as it is not included in the ADV7179.

Part Context

This component belongs to the ADV7174/ADV7179 family of video encoders from Analog Devices. It shares the same core architecture, pinout, and functional block diagram with the ADV7174. The primary distinction lies in feature inclusion; the ADV7179 omits the licensed Macrovision anti-copy processing found in the ADV7174, offering a simplified option for markets where such protection is unnecessary.

Replacement Considerations

The ADV7174 is a direct functional substitute within the same package and pinout configuration. Selection between these two depends solely on the requirement for Macrovision licensing integration. No other electrical or interface differences exist between the models.
