Three-PLL Serial-Programmable
Flash-Programmable Clock Generator
Features
Benefits
Three integrated phase-locked loops (PLLs)
Ultra wide divide counters (8-bit Q, 11-bit P, and 7-bit post
divide)
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 through three external LVTTL inputs
3.3V operation
16-pin TSSOP package
CyClocksRT™ software support
Generates up to three unique frequencies on up to six
outputs from an external source.
Allows for 0 ppm frequency generation and frequency
conversion in the most demanding applications.
Improves frequency accuracy over temperature, age,
process, and initial ppm offset.
Nonvolatile 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
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, communica-
tions, industrial, A/D converters, and consumer applications.
Supports numerous low power application schemes and
reduces electromagnetic interference (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 packaging saves on board space.
Easy to use software support for design entry.
2-wire serial interface 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.
Advanced Features
2-wire serial interface for in-system configurability
Configurable output buffer
Digital VCXO
High frequency LVPECL output (CY22394 only)
3.3/2.5V outputs (CY22395 only)
