CY25811ZXCT

Product Overview

The CY25811ZXCT from Cypress Semiconductor Corp is a surface-mount clock/frequency synthesizer, frequency modulator, and spread spectrum clock generator implemented in an 8-TSSOP package. It operates from a 2.97V to 3.63V supply and supports a maximum frequency of 32MHz. The device accepts clock, crystal, or resonator inputs and provides a clock output, with a specified input-to-output ratio of 1:1 and non-differential input and output interfaces.

Design & Procurement Notes

Design review should confirm that the board supply can maintain 2.97V to 3.63V and that the ambient environment remains within 0°C to 70°C. The 8-TSSOP package is surface mount with a 4.40mm body width, so pad geometry and clearance should match the specified case dimensions. Because the input-to-output ratio is 1:1 and the differential input/output setting is No/No, system timing architecture should be checked against those interface assumptions. The device supports clock, crystal, or resonator inputs and a clock output, with a maximum frequency of 32MHz, so input selection and frequency targets should remain within these parameters.
