Features
·Integrated phase-locked loop (PLL)
·Commercial and Industrial operation
·Flash-programmable
·Field-programmable
·Low-skew, low-jitter, high-accuracy outputs
·3.3V operation with 2.5V output option
·16-lead TSSOP
 Internal PLL to generate six outputs up to 200 MHz. Able to generate custom frequencies from an external reference crystal or a driven source.  Performance guaranteed for applications that require an extended temper-ature range.
 Reprogrammable technology allows easy customization, quick turnaround on design changes and product performance enhancements, and better inventory control. Parts can be reprogrammed up to 100 times, reducing inventory of custom parts and providing an easy method for upgradingexisting designs.
 In-house programming of samples and prototype quantities is available using the CY3672 FTG Development Kit. Production quantities are available through Cypress’s value-added distribution partners or by using third party programmers from BP  Microsystems, HiLo Systems, and others.
 High performance suited for commercial, industrial, networking, telecomm and other general-purpose applications.
 Application compatibility in standard and low-power systems. Industry standard packaging saves on board space.
