ADV7391BCBZ-A-RL

Overview

The ADV7391BCBZ-A-RL 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 including composite (CVBS), S-video (Y-C), component YPrPb, and RGB outputs. The device operates with a 1.8 V digital supply and 2.7 V to 3.3 V analog supply. It accepts multiformat video inputs such as 4:2:2 YCrCb for SD/ED/HD and 4:4:4 RGB for SD. 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 an operating temperature range from -40°C to +85°C.

Procurement Notes

Verify the specific suffix A-RL against official documentation to confirm reel packaging and automotive grade status. Ensure compatibility with required voltage levels and interface protocols before integration. Confirm RoHS compliance and moisture sensitivity ratings for storage and handling requirements.

Selection Notes

Select this model for applications requiring TV-out functionality in portable devices. Consider the 32-lead LFCSP package for minimal footprint. Evaluate power consumption benefits from automatic cable detection features. Verify input format support matches system design requirements.

Part Context

This component belongs to the ADV7390/ADV7391/ADV7392/ADV7393 family of high-speed digital-to-analog video encoders. The ADV7391 variant specifically features an 8-bit video input port supporting SD formats via SDR and HD formats via DDR interfaces. It is designed for low power operation with minimal external components.

Replacement Considerations

Check for ADV7390BCBZ-A-RL or ADV7391BCPZ variants depending on package type. Verify pinout compatibility and electrical specifications. Consult manufacturer documentation for any functional differences between package options.
