CY22394XC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22394XC is a three-PLL serial-programmable flash-programmable clock generator manufactured by Cypress Semiconductor. It integrates three phase-locked loops with ultra-wide divide counters (8-bit Q, 11-bit P, and 7-bit post divide) to generate low jitter, high accuracy outputs. The device operates at 3.3V and features an I2C serial interface for in-system configurability. Key capabilities include configurable crystal drive strength, frequency select via external LVTTL inputs, and power management options such as shutdown and suspend modes.
