Benefits

■

Services most PC peripherals, networking, and consumer

applications.

Provides wide range of spread percentages for maximum

electromagnetic interference (EMI) reduction, to meet

regulatory agency electromagnetic compliance (EMC) require-

ments. Reduces development and manufacturing costs and

time-to-market.

Eliminates the need for expensive and difficult to use higher

order crystals.

Internal PLL to generate up to 200 MHz output. Able to generate

custom frequencies from an external crystal or a driven source.

In-house programming of samples and prototype quantities is

available using the CY3672 programming kit and

CY3690 (TSSOP) or CY3691 (SOIC) socket adapter.

Production quantities are available through Cypress’s value

added distribution partners or by using third party programmers

from BP Microsystems, HiLo Systems, and others.

Enables fine tuning of output clock frequency by adjusting

capacitors.

Suitable for most PC, consumer, and networking applications.

Application compatibility in standard and low power systems.

Ability to enable or disable spread spectrum with an external

pin.

Enables low power state or output clocks to High-Z state.

... CY3691 socket adapters are required to program the CY25100. The CY3690 enables users to program CY25100ZCF and CY25100ZIF (TSSOP). CY3691 provides the ability to program CY25100SCF and CY25100SIF (SOIC). Each socket adapter comes with small prototype quantities of CY25100. The CY3690 and CY3691 is a separate orderable item, so the existing users ...
