ADV7171KSZ-REEL

Overview

The ADV7171KSZ-REEL is a digital PAL/NTSC video encoder manufactured by Analog Devices Inc. It converts digital CCIR-601 4:2:2 component video data into analog baseband signals. The device features four 10-bit DACs and operates on a single 3.3 V or 5 V supply. It supports NTSC M, PAL M/N, PAL B/D/G/H/I, and PAL60 standards with an 80 dB video SNR. The input interface accepts 8-bit or 16-bit parallel data via the CCIR-656 format. Operating temperature ranges from -40°C to +85°C in the industrial grade package.

Feature Summary

• Integrates SSAF (super sub-alias filter) for extended luminance frequency response and sharp stop band attenuation.
• Includes advanced power management circuitry for normal operation and low-power sleep modes.
• Supports simultaneous Y, U, V, C output formats including composite, S-Video, YUV, and RGB EuroSCART.
• Features programmable luma and chroma filters along with integrated color subcarrier locking.

Applications

• High performance DVD playback systems
• Portable video equipment such as digital still cameras and laptop PCs
• Digital satellite and cable set-top boxes

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm that the REEL designation matches the required manufacturing packaging configuration. Ensure compatibility with the target system's voltage requirements and interface protocols before finalizing procurement.

Selection Notes

Select this model when high-quality studio-grade video encoding is required with minimal external components. Verify that the application requires support for multiple international television standards. Consider the MQFP/TQFP package constraints regarding thermal dissipation and PCB layout space availability.

Part Context

This component belongs to the ADV7170/ADV7171 family of integrated digital video encoders. It shares core architecture with the ADV7170 but lacks Macrovision AntiTaping Rev 7.1 support found in the ADV7170 variant. Both devices utilize identical pinouts and register programming structures.

Replacement Considerations

The ADV7170KSTZ serves as a direct functional substitute within the same family. Verify if Macrovision licensing requirements dictate the use of the ADV7170 over the ADV7171. Check for updated package options like the KSU variant which may offer different thermal characteristics.

FAQ

What clock frequency is required for standard operation?

A stable 27 MHz reference clock is required for standard operation, representing a two-times pixel rate oversampling.

Does the ADV7171 support teletext insertion?

Yes, the device includes a dedicated teletext insertion port compatible with PAL-WST standards.

How is the full-scale amplitude of the video signals controlled?

Full-scale amplitudes are controlled by connecting a resistor, typically 150 Ω, from the RSET pin to ground.
