ADV7391BCPZ-REEL

Overview

The ADV7391BCPZ-REEL is a low-power, chip-scale video encoder featuring three 10-bit digital-to-analog converters. It supports standard definition (SD) and high definition (HD) video formats with multiformat input compatibility including 4:2:2 YCrCb and 4:4:4 RGB. The device operates on a 1.8 V digital supply and 2.7 V to 3.3 V analog supply, drawing 81 mA typical current. It utilizes a 32-lead LFCSP package measuring 5 mm × 5 mm. The component functions within a temperature range of −40°C to +85°C and includes advanced power management features such as automatic cable detection and DAC power-down.

Feature Summary

• Supports composite, S-Video, and component video outputs for SD and HD applications
• Integrates patented content-dependent low power DAC operation and sleep mode
• Includes complete on-chip video timing generator and internal test pattern generation
• Features serial MPU interface with I²C compatibility for programmable control

Applications

• Mobile handsets
• Digital still cameras
• Portable media and DVD players
• Portable game consoles
• Digital camcorders

Procurement Notes

Verify the specific REEL suffix indicates tape-and-reel packaging rather than tray distribution. Confirm the B grade designation aligns with the required commercial operating temperature range of −40°C to +85°C. Ensure moisture sensitivity handling protocols are followed during assembly due to the LFCSP construction. Cross-reference the datasheet revision to confirm register map consistency for existing designs.

Selection Notes

Select this model when three independent video DAC outputs are required for component or S-video signals. Choose the ADV7391 over the ADV7390 if Macrovision copy protection support is not needed. Consider the WLCSP variant only if single-channel CVBS output suffices. Verify that the 32-lead footprint fits the target PCB layout constraints compared to the 40-lead ADV7392/ADV7393 options.

Part Context

This component belongs to the ADV739x family of video encoders manufactured by Analog Devices. It shares core architecture with the ADV7390, ADV7392, and ADV7393 but differs in pin count and feature set. The ADV7391 specifically omits Macrovision support found in the ADV7390/ADV7392 models while retaining full SD/HD encoding capabilities in a compact 32-lead package.

Replacement Considerations

The ADV7390BCPZ serves as a functional substitute if Macrovision compliance is required. For automotive applications requiring extended temperature ranges up to +105°C, the ADV7391WBCPZ is the qualified alternative. Direct pin-compatible replacements within the same series include the ADV7392 or ADV7393, though these utilize a larger 40-lead package.
