CY22050
One-PLL General Purpose
Flash Programmable Clock Generator
Features
鈥?Integrated phase-locked loop (PLL)
鈥?Commercial and Industrial operation
鈥?Flash-programmable
Benefits
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 upgrading
existing designs.
In-house programming of samples and prototype quantities is available
using the CY3672 FTG Development Kit. Production quantities are
available through Cypress鈥檚 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.
