Document #: 38-07012 Rev. *D

Revised October 13, 2004

Features

• Three integrated phase-locked loops

• Ultra-wide divide counters (eight-bit Q, eleven-bit P, and

seven-bit post divide)

• Improved linear crystal load capacitors

• Flash programmability

• 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

Benefits

• 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

• 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

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 devel-

opment 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.

• Performance suitable for high-end multimedia, commu-

nications, 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

• 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
