CY22393ZXC-F11

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22393ZXC-F11 is a three-PLL serial-programmable and 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 supports I2C serial interface for in-system configurability. Key features include configurable crystal drive strength, frequency select via external LVTTL inputs, and power management options such as shutdown and suspend modes.
