ISL59450IQZ

Specialized ICS Overview

The ISL59450IQZ is a multi-format video crosspoint switch manufactured by Renesas Electronics Corporation. It supports CVBS, S-Video, YPbPr, and RGB signals within a 128-pin MQFP package. The device features embedded anti-aliasing filters with programmable corner frequencies to eliminate glitch noise from video DACs. It includes two universal sync separators for SD, HD, and computer signals, and outputs have a high impedance disable mode. The component operates over a temperature range of -40°C to +85°C.

Specialized ICS Feature Summary

• Supports 6 Composite, 4 S-Video, and 4 Component Video sources
• Integrated dual sync separators supporting SD, HD, and Computer signals
• Programmable gain of x1 or x2 with high impedance output disable mode
• Compatible with Macrovision encoded signals

Specialized ICS Applications

Specialized ICS Procurement Notes

Verify the manufacturer designation on official documentation, as historical records may list Intersil prior to corporate acquisitions. Confirm that the specific ordering suffix IQZ corresponds to the 128 Ld MQFP package and RoHS compliance status. Ensure compatibility with I2C control interfaces during procurement planning.

Specialized ICS Selection Notes

Select this component for designs requiring simultaneous switching of multiple video formats including CVBS, S-Video, and Component. Verify that the system can provide the required analog supply voltage of 5.0V and digital supply voltage of 3.3V. Consider the 128-BFQFP footprint and thermal resistance of 27.84°C/W for PCB layout and heat dissipation requirements.

Specialized ICS Part Context
