ADV7179KCP-REEL

Overview

The ADV7179KCP-REEL 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 SSAF™ super sub-alias 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/60. It offers programmable simultaneous composite and S-video outputs via a 32-bit direct digital synthesizer for color subcarrier generation. Integrated timing generators support main/subordinate modes with closed captioning and teletext insertion capabilities.

Feature Summary

• Converts digital CCIR-656 4:2:2 pixel data into standard analog composite or component video signals using integrated 10-bit DACs.
• Includes SSAF™ technology to provide studio-quality horizontal line resolution with sharp stop-band attenuation.
• Supports global broadcast standards with programmable luma/chroma filters and square pixel mode operation.
• Integrates on-chip video timing generators allowing flexible main or subordinate system configurations.

Applications

• Portable video applications
• Mobile phones
• Digital still cameras

Procurement Notes

Verify the specific suffix KCP-REEL against the manufacturer's current ordering guide to confirm package type and reel quantity. Ensure the source document matches the exact part number to validate electrical specifications and temperature ranges. Cross-reference the datasheet revision date to ensure compatibility with design requirements.

Selection Notes

Select this component when a compact solution is required for converting digital video streams to analog TV signals. Verify that the system clock frequency matches the required 27 MHz standard or square pixel alternatives. Confirm that the target application operates within the specified voltage range of 2.8 V or 3.3 V and the appropriate temperature grade.

Part Context

This model belongs to the ADV7174/ADV7179 family of video encoders manufactured by Analog Devices Inc. The ADV7179 variant specifically excludes Macrovision anticopy processing found in the ADV7174. Both share identical pinouts, packaging, and core encoding functionalities within a small LFCSP form factor.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official replacement matrix for verified cross-references before implementation.

FAQ

What is the function of the SCRESET/RTC pin?

The SCRESET/RTC pin can be configured as a subcarrier reset input, resetting the subcarrier to Field 0 on a low-to-high transition, or as a real-time control (RTC) input to lock to an external video source.

How does the device handle Teletext data?

A separate Teletext port allows direct input of Teletext data during the vertical blanking interval, supporting PAL-WST protocols through dedicated TTX and TTXREQ pins.

Can the ADV7179 operate in square pixel mode?

Yes, the device supports square pixel operation requiring a 24.5454 MHz clock for NTSC or a 29.5 MHz clock for PAL, with internal timing logic adjusting accordingly.
