CY25701 Datasheet, PDF (1/7 Pages) Cypress Semiconductor – Programmable High-Frequency Crystal Oscillator with Spread Spectrum (SSXO)

CY25701
Programmable High-Frequency Crystal Oscillator
with Spread Spectrum (SSXO)
Features
Benefits
• Crystal Oscillator with Spread Spectrum Clock (SSC)
• Wide operating output (SSCLK) frequency range
• 10–166 MHz
• Programmable spread spectrum with nominal 31.5 kHz
modulation frequency
• Center spread: ±0.25% to ±2.0%
• Down spread: –0.5% to –4.0%
• Integrated phase-locked loop (PLL)
• Low cycle-to-cycle Jitter
• 3.3V operation
• Output Enable function
• Package available in 4-Lead Plastic JE SMD
• Provides wide range of spread percentages for
maximum electromagnetic interference (EMI)
reduction, to meet regulatory agency electromagnetic
compliance (EMC) requirements. Reduces devel-
opment and manufacturing costs and time-to-market.
• Eliminates the need for external crystal oscillator.
• Internal PLL to generate up to 166 MHz output.
• Suitable for most PC, consumer, and networking
applications.
• Application compatibility in standard and low-power
systems.
• In-house programming of samples and prototype
quantities is available using the CY3672 programming
kit and CY3613 socket adapter. Production quantities
are available through Cypress’s value-added distri-
bution partners or by using third-party programmers
from BP Microsystems, HiLo Systems, and others.
