ICS9LRS3187AKLF

Overview

The ICS9LRS3187AKLF is an application-specific clock controller manufactured by Renesas Electronics Corporation. Designed for Intel Hub architecture, this integrated circuit functions as a timing control unit programmed via internal configuration. It accepts a crystal input and generates clock outputs. The device operates on a single 3.3V supply voltage and supports surface mount installation in a 32-VFQFN package with an exposed pad (5x5 mm). It is rated for commercial operating temperatures ranging from 0°C to 70°C.
