CY25404ZXC

Product Overview

The CY25404ZXC from Cypress Semiconductor Corp is a surface-mount spread spectrum clock generator in a 20-TSSOP package. It accepts a clock or crystal input and provides a clock output, with a 1:9 input-to-output ratio and a maximum frequency of 166MHz. The device includes a PLL and supports divider operation but not multiplier operation. Supply voltage is 2.25V to 3.6V, and the operating temperature range is 0°C to 70°C (TA). Differential input and output are not available, making it suitable for single-ended timing interfaces in compact PCB designs.

Key Features

• Spread spectrum clock generator with PLL for timing applications.
• Input accepts clock or crystal signals and output provides a clock signal.
• Maximum frequency is 166MHz with a 1:9 input-to-output ratio.
• Divider function is supported; multiplier function is not supported.
• Supply voltage range is 2.25V to 3.6V.
• Operating temperature range is 0°C to 70°C (TA).
• Surface-mount 20-TSSOP package with 0.173 inch / 4.40mm width.
• Differential input and output are not supported.

Applications

• Embedded timing subsystems that require a spread-spectrum clock output derived from a crystal or external clock input.
• Single-ended clock timing paths in compact surface-mount assemblies using a 20-TSSOP component.
• Clock generation in systems powered from a 2.25V to 3.6V supply.
• Timing generation for equipment operating within 0°C to 70°C ambient.

Design & Procurement Notes

When selecting the CY25404ZXC, confirm that the input source is a clock or crystal and that the required output relationship matches the device's 1:9 ratio. The part is intended for single-ended timing interfaces because differential input and output are not supported. Board layout should accommodate the 20-TSSOP surface-mount package, including the 4.40mm body width. Power and thermal design should keep the supply voltage within 2.25V to 3.6V and the ambient operating temperature within 0°C to 70°C (TA). For frequency-sensitive designs, verify that the required timing frequency is within the 166MHz maximum and that divider-only behavior is acceptable.
