CY25100SXC-029A

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY25100SXC-029A is a field-programmable spread spectrum clock generator manufactured by Infineon Technologies (formerly Cypress Semiconductor). It operates within a supply voltage range of 3.13V to 3.45V and supports input frequencies via CMOS or crystal interfaces. The device features a single circuit configuration with a 1:2 input-to-output ratio, capable of generating output frequencies up to 200MHz. It incorporates both divider and multiplier functions controlled by an internal Phase-Locked Loop (PLL). The component is designed for surface-mount installation in an 8-SOIC package and maintains reliable operation across a temperature range of -40°C to +85°C.
