ICS9154A-27CS16LF

Overview

The ICS9154A-27CS16LF is a single-circuit frequency generator designed for Intel CPU server applications. It accepts crystal input and provides clock output with a 1:05 ratio, supporting frequencies up to 140MHz. The device operates on a supply voltage of 2.97V to 5.5V and functions within an operating temperature range of 0°C to 70°C. Packaged in a 16-SOIC surface-mount case (3.90mm width), it lacks differential input/output capabilities and does not include internal PLL circuitry.
