CY22393
CY22394
CY22395
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.
