CY27020SXCT

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY27020SXCT is a spread spectrum clock generator manufactured by Cypress Semiconductor Corporation. It operates within a commercial temperature range of 0 °C to 70 °C and utilizes an 8-pin small outline integrated circuit (SOIC) package. The device provides a fixed frequency 48.00 MHz output with selectable spread percentages of -1% or -3%. It accepts a 48-MHz reference clock input via an external crystal or direct signal. The unit functions on a 3.3-V supply voltage with 2.5-V functional logic levels, featuring an integrated loop filter and internal pull-up/pull-down resistors for configuration pins.
