CY25814ZCT

Product Overview

The Cypress Semiconductor Corp CY25814ZCT is a surface-mount clock and frequency synthesizer IC supplied in an 8-TSSOP package with a 0.173 inch, 4.40 mm width. The device integrates one PLL-based circuit and supports a maximum frequency of 128 MHz. It accepts clock, crystal, or resonator inputs and provides clock or crystal outputs, with a 1:1 input-to-output ratio and no differential input or output configuration. The part is specified for supply voltage ranges of 2.97 V to 3.465 V and 3.135 V to 3.63 V, and it operates from 0°C to 70°C ambient temperature.

Key Features

• Clock/Frequency Synthesizer, Frequency Modulator, Spread Spectrum Clock Generator
• PLL-based architecture with one circuit and 1:1 input-to-output ratio
• Input types include Clock, Crystal, and Resonator; output types include Clock and Crystal
• Maximum frequency of 128 MHz with divider and multiplier functions
• Non-differential input and output interface
• Surface-mount 8-TSSOP package (0.173 inch, 4.40 mm width)
• Supply voltage ranges: 2.97 V to 3.465 V and 3.135 V to 3.63 V
• Operating temperature range: 0°C to 70°C (TA)

Applications

• Generating clock outputs from crystal, resonator, or clock references in embedded timing circuits.
• Frequency-modulating clock signals through spread-spectrum clock generation in digital assemblies.
• Implementing single-circuit clock synthesis paths that require divider and multiplier functions at frequencies up to 128 MHz.

Design & Procurement Notes

Design and procurement review should confirm that the CY25814ZCT package, 8-TSSOP surface-mount footprint, and 0.173 inch by 4.40 mm body width match the board layout. The selected supply rail must fall within either 2.97 V to 3.465 V or 3.135 V to 3.63 V, and the operating environment should remain within 0°C to 70°C ambient temperature. Because the device is a single circuit with a 1:1 input-to-output ratio and non-differential inputs and outputs, system timing architecture should account for the available clock, crystal, or resonator reference and the required clock or crystal output. Frequency plans should not exceed 128 MHz, and divider or multiplier requirements should be checked against the device's divider and multiplier functions.
