CY22392_08 Datasheet, PDF (1/9 Pages) Cypress Semiconductor – Three-PLL General Purpose FLASH Programmable Clock Generator

CY22392
Three-PLL General Purpose
FLASH Programmable Clock Generator
Features
■ Three integrated phase-locked loops
■ Ultra Wide Divide Counters (8-bit Q, 11-bit P, and 7-bit Post
Divide)
■ Improved Linear Crystal Load capacitors
■ Flash programmability
■ Field programmable
■ Low-jitter, high-accuracy outputs
■ Power-management options (Shutdown, OE, Suspend)
■ Configurable Crystal drive strength
■ Frequency Select through 3 external LVTTL Inputs
■ 3.3V operation
■ 16-pin TSSOP packages
■ CyClocksRT™ Support
Benefits
■ Generates up to 3 unique frequencies on 6 outputs up to 200
MHz from an external source. Functional upgrade for current
CY2292 family.
■ Allows for 0 ppm Frequency Generation and Frequency
Conversion under the most demanding applications.

■ Improves frequency accuracy over temperature, age, process,
and initial offset.
■ Non-Volatile programming enables easy customization,
ultra-fast turnaround, performance tweaking, design timing
margin testing, inventory control, lower part count, and more
secure product supply. In addition, any part in the family can
also 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 is
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 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.
