ADV7343BSTZ

Overview

The ADV7343BSTZ is a high-speed multiformat video encoder manufactured by Analog Devices Inc. It features six 11-bit, 297 MHz digital-to-analog converters (DACs) housed in a 64-lead LQFP package. The device supports standard definition (SD), enhanced definition (ED), and high definition (HD) video formats including NTSC, PAL, SMPTE 274M, and SMPTE 296M. It accepts 8-, 16-, or 24-bit pixel data inputs via SDR or DDR interfaces. Key specifications include a maximum DAC output current of 37 mA, operation from 1.8 V to 3.3 V supplies, and an operating temperature range of −40°C to +85°C.

Feature Summary

• Supports simultaneous SD and ED/HD input/output with integrated oversampling for SD, ED, and HD formats.
• Includes programmable filters, gamma correction, and color space conversion matrices for YCrCb and RGB signals.
• Features embedded copy generation management system (CGMS), closed captioning, and wide screen signaling capabilities.
• Integrates on-chip voltage reference, test pattern generators, and cable detection for power management.

Applications

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

Procurement Notes
