ADV7343WBSTZ

Overview

The ADV7343WBSTZ is a multiformat video encoder featuring six 11-bit, 297 MHz DACs. It supports SD, ED, and HD video formats including NTSC, PAL, SMPTE 274M (1080i), 296M (720p), and 240M (1035i). The device accepts 8-, 16-, or 24-bit digital video inputs in YCrCb or RGB color spaces via SDR or DDR interfaces. It provides composite, S-Video, component YPrPb, and RGB analog outputs with programmable oversampling ratios of 16x for SD, 8x for ED, and 4x for HD. Operating voltages include 3.3 V analog, 1.8 V digital core, and 1.8 V/3.3 V I/O. It operates within a temperature range of −40°C to +85°C.

Feature Summary

• Supports simultaneous standard definition and enhanced/high definition input and output processing.
• Integrates programmable filters for luma, chroma, sharpness, and adaptive control alongside gamma correction.
• Includes embedded copy generation management system (CGMS) and closed captioning capabilities.
• Features integrated voltage reference, cable detection, and DAC autopower-down for power optimization.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the design accommodates the required 3.3 V analog and 1.8 V digital supply rails. Confirm that the PCB layout adheres to the recommended grounding and decoupling specifications for high-speed DAC performance.

Selection Notes

Select this component when multiformat encoding from digital video sources to analog displays is required. It is suitable for designs needing support for both SD and HD standards without external filtering due to internal oversampling. Verify compatibility with the host processor's data interface width and clock frequency requirements.

Part Context

This part belongs to the ADV7342/ADV7343 family of high-speed digital-to-analog video encoders manufactured by Analog Devices Inc. It is designed for applications requiring conversion of digital video signals into various analog broadcast and display formats. The device integrates multiple video processing blocks on a single chip to reduce system complexity.

Replacement Considerations

The ADV7342 is the primary related part number within the same datasheet, sharing identical functional specifications and pinout. Verify if any specific feature differences exist between the WBSTZ variant and other suffixes in the official documentation before substitution.
