AN15851A

Specialized ICS Overview

The AN15851A is a silicon monolithic bipolar integrated circuit designed for color television applications. It functions as a 4-input AV switch with an integrated RGB to YUV converter. The device accepts video signals in G, B, R, Y, U, and V formats across four input channels and provides corresponding outputs. Audio switching is supported via dedicated L/R input and output pins. Control is managed through an I2C bus interface using SCL and SDA pins. The IC operates within a supply voltage range of 8.1V to 9.9V and utilizes a 36-USO (USONF-36D) surface mount package.

Specialized ICS Feature Summary

• Four-channel video input switching with selectable RGB to YUV conversion
• Integrated audio switching for two stereo pairs
• I2C bus control for gain selection, mute, and input routing
• Video gain options of 0dB, 4.4dB, or 6dB depending on output channel

Specialized ICS Applications

• Color Television systems
• AV Switching circuits
• RGB to YUV signal conversion modules

Specialized ICS Procurement Notes

Verify the specific package variant USONF-36D matches the target PCB footprint. Confirm that the I2C slave address 90H is compatible with the system controller. Ensure power supply rails are stable between 8.1V and 9.9V during operation. Check for any obsolescence status as the specification date is from 2002.

Specialized ICS Selection Notes

Select this component when a single IC solution is required for multi-source video and audio switching in TV designs. It is suitable for applications needing RGB to YUV conversion without external logic. Verify that the operating temperature range of -20°C to +70°C meets environmental requirements.
