CY25702
Programmable High-Frequency Crystal Oscillator (XO)
Features
鈥?Programmable High-frequency Crystal Oscillator (XO)
鈥?Wide output (CLK) range from:
鈥?1.0 to 125 MHz (V
DD
= 5.0V)
鈥?1.0 to 90 MHz (V
DD
= 3.3V)
鈥?Integrated phase-locked loop (PLL)
鈥?Low cycle-to-cycle Jitter
鈥?3.3/5.0V operation
鈥?Output Enable function
鈥?Power-down function
鈥?Refer to CY25701 for SSCG function
鈥?Lead-free package
Benefits
鈥?Eliminates the need for external crystal oscillator.
鈥?Internal PLL to generate up to 125-MHz output.
鈥?Suitable for most PC, consumer and networking
applications.
鈥?Application compatibility in standard and low-power
systems.
鈥?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.
鈥?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鈥檚 value-added
distribution partners.
