CY25100
Field- and Factory-Programmable Spread Spectrum
Clock Generator for EMI Reduction
Features
鈥?Wide operating output (SSCLK) frequency range
鈥?3鈥?00 MHz
鈥?Programmable spread spectrum with nominal 31.5-kHz
modulation frequency
鈥?Center spread: 鹵0.25% to 鹵2.5%
鈥?Down spread: 鈥?.5% to 鈥?.0%
鈥?Input frequency range
鈥?External crystal: 8鈥?0 MHz fundamental crystals
鈥?External reference: 8鈥?66 MHz Clock
鈥?Integrated phase-locked loop (PLL)
鈥?Field-programmable
鈥?CY25100SCF and CY25100SIF, 8-pin SOIC
鈥?CY25100ZCF and CY25100ZIF, 8-pin TSSOP
鈥?Programmable crystal load capacitor tuning array
鈥?Low cycle-to-cycle jitter
鈥?3.3V operation
鈥?Commercial and Industrial operation
鈥?Spread Spectrum On/Off function
鈥?Power-down or Output Enable function
Benefits
鈥?Services most PC peripherals, networking, and consumer
applications.
鈥?Provides wide range of spread percentages for maximum
electromagnetic interference (EMI) reduction, to meet
regulatory agency electromagnetic compliance (EMC)
requirements. Reduces development and manufacturing
costs and time-to-market.
鈥?Eliminates the need for expensive and difficult to use
higher-order crystals.
鈥?Internal PLL to generate up to 200-MHz output. Able to
generate custom frequencies from an external crystal or a
driven source.
鈥?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鈥檚
value-added distribution partners or by using third-party
programmers from BP Microsystems, HiLo Systems, and
others.
鈥?Enables fine-tuning of output clock frequency by adjusting
C
Load
of the crystal. Eliminates the need for external C
Load
capacitors.
鈥?Suitable for most PC, consumer, and networking applica-
tions
鈥?Application compatibility in standard and low-power
systems
鈥?Provides ability to enable or disable spread spectrum with
an external pin.
鈥?Enables low-power state or output clocks to High-Z state.
