Features
Three integrated phase-locked loops
Ultra-wide divide counters (eight-bit Q, eleven-bit P, and
seven-bit post divide)
Improved linear crystal load capacitors
Flash programmability
Field programmability
Low-jitter, high-accuracy outputs
Power-management options (Shutdown, OE, Suspend)
Configurable crystal drive strength
Frequency select option via external LVTTL Input
3.3V operation
Eight-pin SOIC package
CyClocks RT support
Benefits
Generates up to three unique frequencies on three
outputs up to 200 MHz from an external source.
Functional upgrade for current CY2081 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 customi-
zation, ultra-fast turnaround, performance tweaking,
design timing margin testing, inventory control, lower
part count, and more secure product supply. 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 devel-
opment 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.
Performance suitable for high-end multimedia, commu-
nications, 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
External frequency select option for PLL1, CLKA, and
CLKB
Industry standard supply voltage
Industry standard packaging saves on board space
Easy-to-use software support for design entry
