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

Functional Description
The CY25702 uses a programmable configuration memory
array to synthesize output frequency.
The CY25702 is a Crystal Oscillator (XO).
The device uses a Cypress proprietary PLL to synthesize the
frequency of the embedded input crystal.
The frequency CLK output can be programmed from 10–125
MHz.
The CY25702 is available in a 4-pin plastic SMD packages
with operating temperature range of –20 to 70°C.

Programming Description
synthesized clock is from 1–125MHz when VDD= 5V and
1–90MHz when VDD = 3.3V.
Field/Factory-Programmable CY25702
Field/Factory programming is available for samples and
manufacturing by Cypress and its distributors. All requests
must be submitted to the local Cypress Field Application
Engineer (FAE) or sales representative. Once the request has
been processed, you will receive a new part number, samples,
and data sheet with the programmed values. This part number
will be used for additional sample requests and production
orders.
Output Enable or Power Down (OE/PD#, pin 1)
Pin 1 can be programmed as either output enable (OE) or
Power Down (PD#).
