BU6520KV-E2

Overview

The BU6520KV-E2 is a video encoder manufactured by ROHM Semiconductor, designed for NTSC/PAL composite video format (CVBS) output. It features an Adaptive Image Enhancer (AIE) function to improve image visibility through brightness correction, backlight correction, and chroma emphasis. The device supports ITU-R BT.656 YCbCr 4:2:2 input with synchronization signals and includes a built-in DAC with direct 75 Ω drive capability. It operates on a core voltage of 1.4V to 1.6V and I/O voltages of 2.7V to 3.6V, functioning within a temperature range of -40°C to +85°C.

Feature Summary

• Built-in Adaptive Image Enhancer (AIE) hardware technology for dynamic range correction, edge-emphasizing filter, and gamma filter.
• Direct 75 Ω drive capability via integrated digital-to-analog converter (DAC).
• Automatic register configuration support through external EEPROM reading upon reset or mode change.
• Dual interface compatibility supporting both 2-line serial (I2C) and SPI-bus protocols.

Applications

• Security camera systems
• Automotive cameras
• Drive recorders

Procurement Notes

Verify the specific suffix E-2 against the official datasheet to confirm packaging specifications and tape-and-reel quantities. Ensure that the ordering quantity aligns with the manufacturer's minimum order requirements for the embossed carrier tape format. Cross-reference the RoHS compliance status with the latest product documentation before finalizing procurement.

Selection Notes

Select the BU6520KV-E2 when fog reduction processing is not required, as this feature is exclusive to the BU6521KV variant. Confirm that the system design accommodates the separate power supply sequencing for VDD, VDDIO, VDDI2C, and AVDD terminals. Verify that the host controller supports the necessary I2C or SPI communication protocols for register initialization.

Part Context

This component belongs to the AIE Adaptive Image Enhancer Series from ROHM Semiconductor. It is part of a family that includes the BU6521KV, which adds fog reduction capabilities. Both devices share identical pinouts, electrical characteristics, and package types, differing primarily in their internal image processing algorithms.

Replacement Considerations

The BU6521KV-E2 serves as a functional substitute if fog reduction processing is desired. No other direct replacements are documented in the provided source material.
