ADV7340BSTZ

Overview

The ADV7340BSTZ is a high-speed multiformat video encoder featuring six 12-bit Noise Shaped Video (NSV) digital-to-analog converters. It supports standard definition, enhanced definition, and high definition video formats including NTSC, PAL, SMPTE 274M, and SMPTE 296M. The device accepts up to a 30-bit pixel input via SDR or DDR interfaces and provides composite, S-Video, component YPrPb, and RGB outputs. Operating from a 3.3 V analog supply and 1.8 V digital supply, it includes integrated timing generators, test patterns, and Macrovision copy protection.

Feature Summary

• Supports simultaneous SD and ED/HD video processing with full-drive DACs eliminating external buffering requirements.
• Includes programmable filters for sharpness, adaptive control, gamma correction, and color space conversion.
• Integrates complete on-chip video timing generation and internal test pattern capabilities.
• Features cable detection and DAC autopower-down mechanisms to minimize power consumption.

Applications

• DVD recorders and players
• High definition Blu-ray DVD players

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to ensure package compatibility and temperature range alignment. Confirm that the required voltage levels match the specified 3.3 V analog and 1.8 V digital operation parameters before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring simultaneous standard and high-definition video encoding. Ensure the host processor supports the required 30-bit parallel interface or DDR configuration. Verify that the system design accommodates the specified 3.3 V and 1.8 V dual-supply architecture for optimal performance.

Part Context

This part belongs to the ADV7340/ADV7341 family of multiformat video encoders manufactured by Analog Devices Inc. The ADV7340BSTZ specifically denotes the version packaged in a 64-lead LQFP format designed for industrial temperature ranges. It serves as a direct hardware implementation for converting digital video streams into various analog broadcast standards.

Replacement Considerations

The ADV7341 is a pin-compatible alternative within the same family. Verify if the specific feature set differences between the ADV7340 and ADV7341 models align with the application requirements before substituting.
