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.
