CY25402SXC-007T

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY25402SXC-007T is a factory-programmed, two-phase-locked-loop (PLL) programmable clock generator with spread spectrum capability. It operates on a single 2.5 V, 3.0 V, or 3.3 V supply and accepts an 8 MHz to 48 MHz crystal input or an 8 MHz to 166 MHz external reference clock. The device synthesizes output frequencies ranging from 3 MHz to 166 MHz across three configurable outputs. It supports glitch-free frequency switching via four selectable settings and features programmable drive strength levels. The component is housed in an 8-pin SOIC package and functions within the commercial temperature range of 0 °C to +70 °C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Dual fully integrated PLLs enable independent synthesis of unrelated frequencies from a single reference source.
• Programmable spread spectrum modulation reduces electromagnetic interference using center or down spread profiles.
• Glitch-free frequency switching allows uninterrupted system operation when transitioning between programmed clock rates.
• One-time programmability configures nonvolatile parameters including output frequencies, drive strength, and load capacitance.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific suffix matches the required operating temperature range and packaging format. Confirm the factory-programmed configuration file aligns with the target application frequencies. Ensure the voltage supply requirements match the selected part variant before integration into the design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for applications requiring dual independent clock outputs from a single oscillator source. Verify compatibility with the system's input reference voltage level and required output drive strengths. Consider the commercial temperature range limits when designing for environments exceeding standard room temperatures.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CY25402/CY25422/CY25482 family of two-PLL programmable clock generators. The CY25402 variant specifically supports higher voltage supplies compared to the low-voltage CY25422. All members share identical pinouts and functional architectures but differ in supply voltage specifications and input reference capabilities.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY25402 variants with different temperature ratings or packaging options. Cross-model substitution requires verifying supply voltage compatibility against CY25422 or CY25482 specifications. Factory programming must be reconfigured for any substitute part number.
