BU16018KV-E2

Video Processing Overview

The BU16018KV-E2 is an HDMI switch IC from Rohm Semiconductor designed for consumer video applications. It supports a signaling rate of up to 2.25 Gbps, compatible with HDMI 1.3a standards and resolutions including 480i/p, 720p, and 1080i/p at color depths up to 12-bit. The device features a 3-to-1 input configuration with one output, operating on a fixed 3.3V supply voltage (range 3V to 3.6V). It integrates active DDC buffers, switchable 50Ω termination resistors, and equalizer circuits for long cable adaptation. The component utilizes GPIO control via S1, S2, and S3 pins, housed in an 80-pin VQFP package.

Video Processing Feature Summary

• Supports high-speed TMDS data transmission up to 2.25 Gbps for multi-resolution video signals.
• Integrates switchable 50Ω termination resistors that disconnect when channels are inactive.
• Includes built-in equalizer circuitry to compensate for signal degradation over long cables.
• Features 5V tolerance on all DDC and HPD_SINK inputs for robust interface compatibility.

Video Processing Applications

• Digital televisions
• Audio Video Receivers (AVR)
• Digital projectors
• HDMI or DVI switch boxes

Video Processing Procurement Notes

Verify the specific suffix E2 corresponds to the embossed tape and reel packaging format as defined in the manufacturer's ordering information. Confirm the 80-pin VQFP package dimensions match the design layout requirements. Ensure the source material explicitly supports the availability status for this exact part number variant before finalizing procurement plans.

Video Processing Selection Notes

Select this component for designs requiring three independent HDMI sources routed to a single sink. The integrated DDC buffer simplifies connection to downstream displays by isolating capacitance. The fixed 3.3V supply requirement dictates the power rail architecture. Verify that the GPIO control logic aligns with the system's microcontroller capabilities for source selection.

Video Processing Part Context

This model belongs to the BU160xxKV family of HDMI switch ICs manufactured by Rohm Semiconductor. The series includes variants such as the BU16006KV, BU16024KV, and BU16027KV, which differ primarily in the number of supported inputs and package types. The BU16018KV specifically provides a 3-to-1 switching matrix, distinguishing it from the 2-to-1 and 1-to-1 configurations found in other family members.
