CY25701 Datasheet | Cypress

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 k Hz 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 = 133 MHz 3.3V operation Output enable function Package available in 4-Pin ceramic LCC SMD Pb-free package Industrial temperature from - 40°C to 85°C Provides a wide range of spread percentages for maximum electromagnetic interference (EMI) reduction to meet regulatory agency electromagnetic pliance (EMC) requirements. Reduces development and manufacturing costs and time-to-market. This versatile programming feature enables the user 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 patibility in standard and low-power systems In house programming of samples and prototype quantities is available using CY3672 programming kit and CY3724 socket adapters. Production quantities are available through Cypress’ value added distribution partners or by using third party programmers from BP Microsystems, and Hi Lo Systems, and others. - .. - - - - Logic Block Diagram Pin Configuration 4-pin Ceramic SMD PLL with MODULATION CONTROL 4 VDD 3 SSCLK C XIN PROGRAMMABLE CONFIGURATION C XOUT OUTPUT DIVIDERS and MUX 3 SSCLK OE 1 VSS 2 1 OE 4 VDD 2 VSS Cypress Semiconductor Corporation Document Number: 001-07313 Rev. - B - 198 Champion Court - San Jose, CA 95134-1709 - 408-943-2600 Revised August 24, 2007 Pin Definition Pin 1 2 3 4 OE VSS SSCLK VDD Name Power supply ground Spread spectrum clock output (with or without spread) 3.3V power supply Description Output Enable pin: Active...
