Three-PLL Serial-Programmable

Flash-Programmable Clock Generator

Benefits

Features

• Three integrated phase-locked loops (PLLs)

• Generates up to three unique frequencies on up to six

outputs from an external source.

• Ultra-wide divide counters (8-bit Q, 11-bit P, and 7-bit

post divide)

• Allows for 0-ppm frequency generation and frequency

conversion in the most demanding applications.

• Improved linear crystal load capacitors

• Flash programmability with external programmer

• Field-programmable

• Low-jitter, high-accuracy outputs

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

• Configurable crystal drive strength

• Frequency select via three external LVTTL inputs

• 3.3V operation

• Improves frequency accuracy over temperature, age,

process, and initial ppm offset.

• Non-volatile programming enables easy customization,

ultra-fast turnaround, performance tweaking, design timing

margintesting,inventorycontrol,lowerpartcount,andmore

secure product supply. In addition, any part in the family can

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

are available using the CY3672 FTG Development Kit.

Production quantities are available through Cypress

Semiconductor’s value-added distribution partners or by

usingthird-partyprogrammersfromBPMicrosystems, HiLo

Systems, and others.

• Performance suitable for high-end multimedia, communica-

tions, industrial, A/D converters, and consumer applica-

tions.

• Supports numerous low-power application schemes and

reduces electromagnetic interference (EMI) by allowing

unused outputs to be turned off.

• 16-pin TSSOP package

• CyClocksRT™ support

Advanced Features

• Serial-programmable

• Configurable output buffer

• Digital VCXO

• High-frequency LVPECL output (CY22394 only)

• 3.3/2.5V outputs (CY22395 only)

• 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.

• Allows in-system programming into volatile configuration

memory. All frequency settings can be changed providing

literally millions of frequency options.

• Adjust output buffer strength to lower EMI or improve timing

margin.

• Fine tune crystal oscillator frequency by changing load

capacitance.

• Differential output up to 400 MHz.

• Provides interfacing option for low-voltage parts.
