ADV7342BSTZ

Overview

The ADV7342BSTZ is a high-speed digital-to-analog video encoder housed in a 64-lead LQFP package. It integrates six 11-bit, 297 MHz video DACs to support composite (CVBS), S-Video (Y/C), and component (YPrPb/RGB) analog outputs for standard definition (SD), enhanced definition (ED), and high definition (HD) formats. The device features a 24-bit pixel input port compatible with YCrCb or RGB color spaces, supporting SD over SDR and ED/HD over SDR or DDR interfaces. Key specifications include 16× oversampling for SD, 8× for ED, and 4× for HD, with a maximum DAC output current of 37 mA. It operates on 3.3 V analog and 1.8 V digital supplies within a −40°C to +85°C temperature range.

Feature Summary

• Supports simultaneous SD and ED/HD input and output processing.
• Includes integrated subcarrier locking, complete video timing generation, and test pattern generation.
• Features programmable luma/chroma filters, gamma correction, and adaptive filter control.
• Provides Macrovision copy protection compliance and closed captioning support.

Applications

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

Procurement Notes

Verify the specific suffix BSTZ against the manufacturer's ordering guide to confirm package type and automotive qualification status. Ensure the source document matches Rev. E specifications. Confirm voltage levels match system requirements before integration.

Selection Notes

Select this component when multiformat video encoding from digital pixel data to analog outputs is required. It supports both YCrCb and RGB inputs. Consider the 64-lead LQFP package constraints and power supply requirements for 3.3 V analog and 1.8 V digital domains during design.

Part Context

This part belongs to the ADV7342/ADV7343 family of multiformat video encoders. The ADV7342 variant specifically includes Macrovision Rev 7.1.L1 for SD and Rev 1.2 for ED, whereas the ADV7343 lacks these specific copy protection features. Both share identical core encoding capabilities.

Replacement Considerations

The ADV7343BSTZ is the primary functional counterpart within the same datasheet, differing primarily in copy protection features. Verify if Macrovision support is required for the target application before substituting.
