ML86640TBZ0AX

Encoders, Decoders, Converters Overview

The ML86640TBZ0AX is a digital video encoder manufactured by ROHM Semiconductor under the LAPIS brand. It converts digital image inputs, such as ITU-R BT.656 and BT.601 formats, into analog NTSC or PAL composite video signals. The device supports various input data formats including YCbCr 4:2:2 (8/16-bit) and RGB 4:4:4 (24-bit), with clock frequencies up to 54MHz for progressive input. It features P/I conversion for interlacing progressive scan data, internal color bars, and brightness/chroma level adjustments. Operating on a single 3.3V supply, it functions within an industrial temperature range of -40°C to 105°C and utilizes a 48-pin TQFP package.

Encoders, Decoders, Converters Procurement Notes

Verify the specific suffix TBZ0AX against official ROHM documentation to confirm pinout and electrical characteristics match the intended design requirements. Ensure the component meets the required industrial temperature grade specifications for the target application environment before finalizing procurement plans.

Encoders, Decoders, Converters Selection Notes

Select this model when a compact solution is needed to encode digital video signals into standard analog composite formats for display devices. Consider its support for multiple input resolutions and scanning modes if the system requires flexible video source compatibility. Verify that the 3.3V single-supply operation aligns with the system's power architecture.

Encoders, Decoders, Converters Part Context

This component belongs to the LAPIS ML86640 series of digital video encoders produced by ROHM Semiconductor. The series is designed for applications requiring reliable conversion of digital video streams to analog outputs. The ML86640TBZ0AX variant specifically denotes the automotive-grade or industrial-grade version packaged in a TQFP48 format, suitable for space-constrained electronic assemblies.

Encoders, Decoders, Converters Replacement Considerations

Direct replacements should be sought from the same LAPIS ML86640 family to ensure pin compatibility and functional equivalence. Verify that any substitute part maintains the same input/output signal standards and operating voltage requirements.
