CY22381

Three-PLL General Purpose FLASH

Programmable Clock Generator

■ Improves frequency accuracy over temperature, age, process,

and initial offset

Features

■ Three integrated phase-locked loops

■ Non-volatile programming enables easy customization,

ultra-fast turnaround, performance tweaking, design timing

margin testing, inventory control, lower part count, and more

secureproductsupply. Canalsobeprogrammedmultipletimes

which reduces programming errors and provides an easy

upgrade path for existing designs

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

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 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.

■ Field programmability

■ Low-jitter, high-accuracy outputs

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

■ Configurable crystal drive strength

■ Frequency select option through external LVTTL Input

■ 3.3V operation

■ 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

■ Eight-pin SOIC package

■ CyClocks RT™ support

■ Adjust crystal drive strength for compatibility with virtually all

crystals

Benefits

■ External frequency select option for PLL1, CLKA, and CLKB

■ Generates up to three unique frequencies on three outputs up

to 200 MHz from an external source. Functional upgrade for

current CY2081 family.

■ Industry standard supply voltage

■ Industry standard packaging saves on board space

■ Easy-to-use software support for design entry

■ Allows for 0 ppm frequency generation and frequency

conversion under the most demanding applications
