CY25701JXC Datasheet, PDF (1/7 Pages) Cypress Semiconductor – Programmable High-Frequency Crystal Oscillator with Spread Spectrum (SSXO) and No-Spread Spectrum (XO) Option

CY25701JXC/FJXC
Programmable High-Frequency Crystal Oscillator with Spread
Spectrum (SSXO) and No-Spread Spectrum (XO) Option
Features
Benefits
• Crystal Oscillator with Spread Spectrum Clock (SSXO)
• No-Spread Spectrum (XO) Option
• Wide operating output clock frequency range of
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%
• No spread: ± 0.0%
• Integrated phase-locked loop (PLL)
• 85 ps typical cycle-to-cycle Jitter with SSCLK = 133MHz
• 3.3V operation
• Output Enable function
• Package available in 4-pin Plastic JE
• Pb-free package
• 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.
• This versatile programming feature enables the users
to switch between SSXO (with Spread) and XO (without
Spread) functions with ease.
• 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 (JEC package) socket adapters.
Production quantities are available through Cypress’
value-added distribution partners or by using
third-party programmers from BP Microsystems, HiLo
Systems, and others.
