ADV7391WBCPZ

Overview

The ADV7391WBCPZ is a low-power, chip-scale video encoder featuring three 10-bit digital-to-analog converters. It supports standard definition (SD), enhanced definition (ED), and high definition (HD) video formats including NTSC, PAL, SMPTE 274M, and SMPTE 296M. The device operates with a digital supply voltage of 1.71 V to 1.89 V and an analog supply voltage of 2.6 V to 3.465 V. It utilizes a 32-lead, 5 mm × 5 mm Lead Frame Chip Scale Package (LFCSP). The component includes advanced power management features such as automatic cable detection and DAC power-down.

Feature Summary

• Supports multiformat video input including 4:2:2 YCrCb for SD/ED/HD and 4:4:4 RGB for SD.
• Provides flexible output configurations for composite, S-Video, component YPrPb, and component RGB.
• Integrates content-dependent low power DAC operation with individual DAC on/off control capabilities.
• Includes complete on-chip video timing generation and internal test pattern generation.

Applications

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

Procurement Notes

Verify the specific automotive grade suffix 'WB' corresponds to the extended temperature range of -40°C to +105°C when sourcing. Confirm package dimensions match the 32-LFCSP (5x5) specification. Ensure compatibility with I2C control interfaces during integration. Validate that the W-grade qualification meets project reliability requirements before finalizing procurement orders.

Selection Notes

Select this model for applications requiring HD video encoding in a minimal footprint. Choose this part over non-W variants if operation beyond +85°C is required. Verify that the 8-bit SD or DDR HD input interface matches the source system. Consider the ADV7390 or ADV7392 only if different input port widths or specific ED features are needed.

Part Context

This component belongs to the ADV739x family of video encoders from Analog Devices. The family shares core architecture but differs in input bit-width and package options. The ADV7391 specifically targets portable devices needing SD and HD TV-out functionality. It complements other ADV739x parts by offering a balance of performance and power efficiency in a compact form factor.
