ADV7179KCPZ

Overview

The ADV7179KCPZ is a chip-scale PAL/NTSC video encoder that converts ITU-R BT.601/BT.656 YCrCb digital video data into analog baseband television signals. It features high-quality 10-bit video DACs and an integrated super sub-alias filter (SSAF) for studio-quality output. The device supports multiple video standards including NTSC M, PAL N2, and various PAL variants. It operates on a single 2.8 V or 3.3 V supply and includes advanced power management with sleep mode capabilities. The encoder provides composite, S-video, and component outputs via programmable DAC configurations.

Feature Summary

• Supports CCIR-656 4:2:2 8-bit parallel input format for direct interface with MPEG decoders
• Includes SSAF technology for extended luminance frequency response and sharp stop-band attenuation
• Features programmable luma and chroma filters with selectable responses for CIF and QCIF formats
• Integrates closed captioning support, CGMS-A, and WSS data generation capabilities

Applications

• Portable video applications
• Mobile phones
• Digital still cameras

Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. Ensure the procurement channel provides valid traceability documentation. Confirm that the component meets AEC-Q100 automotive qualification requirements if intended for such environments. Check for any recent revision updates in the datasheet that may affect pin compatibility or electrical specifications.

Selection Notes

Select this encoder when a compact solution for converting digital YCrCb data to analog TV signals is required. It is suitable for designs needing simultaneous composite and S-video outputs. Consider the power consumption differences between 2.8 V and 3.3 V operation modes. Ensure the system clock can provide the necessary 27 MHz reference or square pixel frequencies.

Part Context

This component belongs to the ADV7174/ADV7179 family of video encoders from Analog Devices. The ADV7179 variant specifically excludes Macrovision anti-copy protection found in the ADV7174. Both share identical pinouts and core functionality, differing primarily in licensing features. The KCPZ suffix indicates a lead-free LFCSP package with specific thermal characteristics.

Replacement Considerations

The ADV7174 is a functional substitute with added Macrovision support. Verify if the target application requires copy protection features before swapping. Other members of the ADV717x family may offer different package options or additional I/O capabilities. Ensure register compatibility when migrating between closely related encoder models.
