CY22393FXIT

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22393FXIT is a three-PLL, serial-programmable, flash-programmable clock generator manufactured by Infineon Technologies. It operates on a single 3.3 V supply and features six CMOS outputs within a 16-pin TSSOP package. The device supports an external crystal input frequency range of 8 MHz to 30 MHz or a reference clock from 1 MHz to 166 MHz. Maximum output frequencies reach up to 200 MHz for commercial variants and 166 MHz for industrial temperature grades.
