ADV7391BCPZ

Overview

The ADV7391BCPZ 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 supplies, drawing a maximum operating current of 81 mA. It utilizes a 32-lead, 5 mm × 5 mm LFCSP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports composite, S-video, and component analog outputs for SD and HD formats
• Includes patented content-dependent low power DAC operation and automatic cable detection
• Features integrated subcarrier locking and complete on-chip video timing generation

Applications

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

Procurement Notes

Verify the specific suffix BCPZ corresponds to the 32-lead LFCSP package variant when sourcing. Confirm that the intended application requires the 8-bit input interface characteristic of the ADV7391 model rather than the 16-bit interface found in other family members. Ensure compliance with RoHS directives as indicated by the Z suffix.

Selection Notes

Select this component for designs requiring TV-out functionality in portable devices where minimal footprint and low power consumption are critical. The ADV7391 is suitable for applications needing SD and HD video encoding via an 8-bit parallel interface. Consider alternative family members if a 16-bit input port or automotive qualification is required.

Part Context

This part belongs to the ADV7390/ADV7391/ADV7392/ADV7393 family of monolithic video encoders. While sharing core encoding capabilities, the ADV7391 specifically features an 8-bit video input port supporting SD over SDR and HD over DDR interfaces. Other family variants offer different input widths or automotive grades.

Replacement Considerations

The ADV7390BCPZ serves as a functional substitute within the same package, differing primarily in input configuration support. The ADV7391WBCPZ offers a WLCSP package option but provides only a single DAC output for SD CVBS.
