ADV7390WBCPZ-RL

Overview

The ADV7390WBCPZ-RL is a low-power, chip-scale video encoder manufactured by Analog Devices Inc. It features three 10-bit video DACs supporting composite (CVBS), S-Video (Y-C), and component (YPrPb/RGB) analog outputs for standard definition (SD) and high definition (HD) formats. The device operates with 2.7 V or 3.3 V analog supplies and 1.8 V digital logic. It includes an 8-bit video input port compatible with SD SDR and HD DDR interfaces. Key specifications include a maximum DAC output current of 37 mA, oversampling rates of 16× for SD, 8× for ED, and 4× for HD, and support for embedded EAV/SAV timing codes. The component is housed in a 32-lead LFCSP package.

Feature Summary

• Supports multiformat video inputs including 4:2:2 YCrCb for SD, ED, and HD, and 4:4:4 RGB for SD.
• Provides programmable luma and chroma filter responses with vertical blanking interval data insertion capabilities.
• Integrates advanced power management featuring content-dependent low power operation and automatic cable detection.
• Includes complete on-chip video timing generation and internal test pattern generation functions.

Applications

• Mobile handsets
• Digital still cameras
• Portable media and DVD players
• Set-top box (STB)
• Digital camcorders

Procurement Notes

Verify the specific suffix WBCPZ-RL against the manufacturer's ordering guide to confirm the reel packaging configuration. Ensure compatibility with the required automotive temperature range (-40°C to +105°C) if applicable. Confirm that the I2C interface requirements match the system design constraints before finalizing procurement.

Selection Notes

Select this model when an 8-bit video input interface is required for SD and HD encoding. Compare against the ADV7391 for identical functionality or the ADV7392/ADV7393 if a 16-bit input port and SD RGB support are necessary. Consider the LFCSP-32 package size for space-constrained portable designs requiring TV-out functionality.

Part Context

This component belongs to the ADV739x family of monolithic video encoders. It shares core architecture with the ADV7391 but differs in pinout or specific feature configurations compared to the 16-bit input variants like the ADV7392 and ADV7393. The family is designed for portable applications needing minimal external components.

Replacement Considerations

The ADV7391WBCPZ-RL is a functional equivalent within the same series. Verify pin-to-pin compatibility and register mapping differences before substitution. No other direct substitutes are confirmed in public documentation.

FAQ

What video input interfaces does the ADV7390 support?

The ADV7390 supports an 8-bit video input port that handles SD video formats via a Single Data Rate (SDR) interface and HD video formats via a Dual Data Rate (DDR) interface.

Does the ADV7390 support embedded timing codes?

Yes, the device supports embedded EAV/SAV timing codes for both standard definition and high definition video formats.

What is the maximum DAC output current capability?

The maximum DAC output current is 37 mA when the RSET resistor is 510 Ω and the load resistance is 37.5 Ω.
