CY25423SXC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY25423SXC is a field-programmable clock generator featuring three fully integrated phase-locked loops (PLLs) with spread spectrum capability. It supports an external crystal input frequency range of 8 to 48 MHz and an external reference clock range of 8 to 166 MHz. The device operates at a supply voltage of 1.8 V, with a specified range of 1.65 V to 1.95 V. It is housed in an 8-pin SOIC package and is rated for commercial temperature operation from 0 °C to 70 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer origin, as the component is associated with both Cypress Semiconductor Corp and Infineon Technologies due to corporate acquisition history. Confirm the specific suffix 'SXC' corresponds to the 8-pin SOIC package and commercial temperature grade. Ensure documentation aligns with the original Cypress specifications or the updated Infineon data sheet to avoid discrepancies in electrical parameters or pin configurations.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a design requires multiple synchronized clock outputs derived from a single reference source. The integrated spread spectrum feature is critical for applications where strict electromagnetic compatibility standards must be met without additional filtering components. Verify that the required output frequencies fall within the programmable range supported by the internal PLL architecture.
