CY25702 Datasheet, PDF (1/7 Pages) Cypress Semiconductor – Programmable High-Frequency Crystal Oscillator (XO)

CY25702
Programmable High-Frequency Crystal Oscillator (XO)
Features
• Programmable High-frequency Crystal Oscillator (XO)
• Wide output (CLK) range from:
— 1.0 to 125 MHz (V_DD = 5.0V)
— 1.0 to 90 MHz (V_DD = 3.3V)
• Integrated phase-locked loop (PLL)
• Low cycle-to-cycle Jitter
• 3.3/5.0V operation
• Output Enable function
• Power-down function
• Refer to CY25701 for SSCG function
• Lead-free package
Benefits
• Eliminates the need for external crystal oscillator.
• Internal PLL to generate up to 125-MHz output.
• Suitable for most PC, consumer and networking
applications.
• Application compatibility in standard and low-power
systems.
• CY25701 can be used as a direct replacement in 3.3V
applications if Spread Spectrum Clock (SSC) is
required for EMI reduction without any PCB
modification.
• In-house programming of samples and prototype
quantities is available using the CY3672 programming
kit and CY36xx socket adapter. Sample and production
quantities are available through Cypress’s value-added
distribution partners.
