CY27020SC

Product Overview

Cypress Semiconductor Corp CY27020SC is a single-circuit spread spectrum clock generator supplied in an 8-SOIC (0.154", 3.90mm Width) surface-mount package. The device accepts a crystal input, includes a PLL, and provides a clock output with a 1:2 input-to-output ratio. Its maximum frequency is 48MHz. The input and output are non-differential, and the device does not include divider or multiplier functions beyond the specified ratio. It operates from a 2.97V to 3.63V supply and is specified for an ambient operating temperature range of 0°C to 70°C. The package footprint is suitable for surface-mount assembly, and the single-circuit architecture supports one clock generation path within the stated supply and temperature limits.

Design & Procurement Notes

Designers should verify that the required frequency plan matches the 1:2 input-to-output ratio and the 48MHz maximum frequency. Because the device provides one circuit and non-differential input and output, it is suitable for single-ended clock paths rather than differential clocking. The 2.97V to 3.63V supply range and 0°C to 70°C ambient range should be checked against the board power and thermal environment. The 8-SOIC package requires a surface-mount footprint and appropriate assembly process. Since no divider or multiplier functions are included, external clock planning should account for the crystal input and single clock output. Crystal compatibility should be verified against the selected crystal's own characteristics.
