Three-PLL General Purpose FLASH

Programmable Clock Generator

• Non-volatile programming enables easy customi-

zation, ultra-fast turnaround, performance tweaking,

design timing margin testing, inventory control, lower

part count, and more secure product supply. Can also

Features

• Three integrated phase-locked loops

• Ultra-widedividecounters(eight-bitQ,eleven-bitP,and

be programmed multiple times which reduces

programming errors and provides an easy upgrade

path for existing designs

seven-bit post divide)

• Improved linear crystal load capacitors

• Flash programmability

• In-house programming of samples and prototype

quantities is available using the CY3672 FTG devel-

opmentKit.Productionquantitiesareavailablethrough

Cypress’s value-added distribution partners or by

using third party programmers from BP Microsystems,

HiLo Systems, and others.

• Performance suitable for high-endmultimedia, commu-

nications, industrial, A/D converters, and consumer

applications

• Field programmability

• Low-jitter, high-accuracy outputs

• Power-management options (Shutdown, OE, Suspend)

• Configurable crystal drive strength

• Frequency select option via external LVTTL Input

• 3.3V operation

• Eight-pin SOIC package

• CyClocks RT™ support

• Supports numerous low-power application schemes

and reduces EMI by allowing unused outputs to be

turned off

• Adjust crystal drive strength for compatibility with

Benefits

virtually all crystals

• External frequency select option for PLL1, CLKA, and

CLKB

• Industry standard supply voltage

• Industry standard packaging saves on board space

• Easy-to-use software support for design entry

• Generates up to three unique frequencies on three

outputs up to 200 MHz from an external source.

Functional upgrade for current CY2081 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
