CY25404ZXI-004

Product Overview

The Cypress Semiconductor Corp CY25404ZXI-004 is a programmable PLL-based spread-spectrum clock generator for surface-mount digital timing designs. It accepts clock or crystal inputs and produces a clock output, with a maximum frequency of 166 MHz and an input-to-output ratio of 1:9. The device operates from a 2.25 V to 3.6 V supply and is rated for an ambient temperature range of -40°C to 85°C. It uses a 20-TSSOP package with a 0.173 inch (4.40 mm) body width, for designs requiring a single non-differential clock generator function.

Applications

• Board-level clock generation in embedded digital systems
• Timing synthesis from crystal or external clock references
• Spread-spectrum clock generation in systems that require a spread-spectrum clock output
• Single-output clock distribution for surface-mount logic boards

Design & Procurement Notes

When selecting this device, confirm that the system input can accept a clock source or crystal and that the required output frequency remains at or below 166 MHz. The 1:9 input-to-output ratio and non-differential input/output configuration should be matched to the target timing architecture. Board layout should account for the 20-TSSOP footprint and surface-mount assembly, while the power supply must remain within 2.25 V to 3.6 V. Thermal design should verify that the ambient temperature stays within -40°C to 85°C. The divider/multiplier configuration is divider yes and multiplier no; frequency planning should reflect the 1:9 input-to-output ratio.
