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%
www.Da• taDSohwenets4Up.rceoamd: –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.

Notes:
4. The “Informational Graphs” are meant to convey the typical performance levels. No performance specifications is implied or guaranteed. Refer to the tables on
pages 4 and 5 for device specifications.
5. “ZZZ” denotes the assigned product dash number. This number will be assigned by factory after the output frequency and spread percent programming data is
received from the customer.
6. “FJXC” suffix is used for products programmed in field by Cypress distributors.
