CY25403/CY25423/CY25483

Three PLL Programmable Clock Generator

with Spread Spectrum

Features

■ Three fully integrated phase-locked loops (PLLs)

■ Three clock outputs with programmable drive strength

■ Glitch-free outputs while frequency switching

■ 8-pin SOIC package

■ Input frequency range

❐ External crystal: 8 to 48 MHz

❐ External reference: 8 to 166 MHz clock

■ Commercial and Industrial temperature ranges

■ Reference clock input voltage range

❐ 1.8 V for CY25403/CY25423/CY25483

Benefits

■ Wide operating output frequency range

❐ 3 to 166 MHz

■ Multiple high performance PLLs allow synthesis of unrelated

frequencies

■ Programmable spread spectrum with center and down spread

option and lexmark and linear modulation profiles

■ Nonvolatile programming for personalization of PLL

frequencies, spread spectrum characteristics, drive strength,

crystal load capacitance, and output frequencies

■ V_DDsupply voltage options:

❐ 2.5 V, 3.0 V, and 3.3 V for CY25403/CY25423/CY25483

■ ApplicationspecificprogrammableEMIreductionusingSpread

Spectrum for clocks

■ Selectable output clock voltages independent of V_DDsupply:

❐ 2.5 V, 3.0 V, and 3.3 V for CY25403/CY25423/CY25483

■ Programmable PLLs for system frequency margin tests

■ Frequency select feature with option to select four different

frequencies

■ Meets critical timing requirements in complex system designs

■ Suitability for PC, consumer, portable, and networking

applications

■ Power-down, output enable, and SS ON/OFF controls

■ Low jitter, high accuracy outputs

■ Capable of Zero PPM frequency synthesis error

■ AbilitytosynthesizenonstandardfrequencieswithFractional-N

capability

■ Uninterrupted system operation during clock frequency switch

■ Application compatibility in standard and low power systems
