  CY22393F单片机 Benefits
  Generates up to three unique frequencies on up to six outputs from an external source.
  Allows for 0-ppm frequency generation and frequency conversion in the most demanding applications.
  Improves frequency accuracy over temperature, age, process, and initial ppm offset.
  Non-volatile programming enables easy customization,ultra-fast turnaround, performance tweaking, design timingmargin testing, inventory control, lower part count, and more secure product supply. In addition, any part in the family can be programmed multiple times, which reduces programming errors and provides an easy upgrade path for existing designs.
  In-house programming of samples and prototype quantities are available using the CY3672 FTG Development Kit.Production quantities are available through Cypress Semiconductor’s value-added distribution partners or by using third-party programmers from BP Microsystems, HiLo Systems, and others.
  Performance suitable for high-end multimedia, communications,industrial, A/D converters, and consumer applications.
  Supports numerous low-power application schemes and reduces electromagnetic interference (EMI) by allowing unused outputs to be turned off.
  Adjust crystal drive strength for compatibility with virtually all crystals.
  3-bit external frequency select options for PLL1, CLKA, and CLKB.
  Industry-standard supply voltage.
  Industry-standard packaging saves on board space.
  Easy to use software support for design entry.
  Allows in-system programming into volatile configuration memory. All frequency settings can be changed providing literally millions of frequency options.
  Adjust output buffer strength to lower EMI or improve timing margin.
  Fine tune crystal oscillator frequency by changing load capacitance.
  Differential output up to 400 MHz.
  Provides interfacing option for low-voltage parts.
