ADV7391WBCPZ-RL

Overview

The ADV7391WBCPZ-RL 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 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 a 2.7 V to 3.3 V analog supply, housed in a 32-lead LFCSP package. It includes advanced power management features such as automatic cable detection, DAC power-down, and sleep mode.

Feature Summary

• Supports composite, S-Video, and component video outputs for SD, ED, and HD formats
• Includes patented content-dependent low power DAC operation and automatic cable detection
• Features integrated subcarrier locking, closed captioning, and wide screen signaling
• Provides programmable luma/chroma filters, gamma correction, and adaptive filter control

Applications

• Mobile handsets
• Digital still cameras
• Portable media and DVD players
• Set-top boxes

Procurement Notes

Verify the specific suffix WBCPZ-RL indicates reel packaging when sourcing. Confirm automotive grade qualification if operating within the extended temperature range of -40°C to +105°C. Ensure I/O voltage levels match system requirements before integration.

Selection Notes

Select this model for portable applications requiring minimal footprint and low power consumption. Verify that the 32-lead LFCSP package fits the PCB layout constraints. Check compatibility with existing video timing generators and MPU interfaces for seamless integration.

Part Context

This component belongs to the ADV739x family of video encoders from Analog Devices. It shares core architecture with the ADV7390, ADV7392, and ADV7393 but differs in pin count and input configuration. The WBCPZ suffix denotes the automotive-grade variant in a lead frame chip scale package.

Replacement Considerations

ADV7391WBCPZ is a direct pin-compatible alternative. ADV7390/ADV7392/ADV7393 share similar functionality but may require interface adjustments due to different pin counts or input widths.
