The 1:3 fanout ratio lets a single reference clock feed three downstream loads — common in FPGA, SoC, or memory-controller clock trees where a clean multiplied clock is needed without adding a separate oscillator per load. The supply range (3V to 3.6V) centres on 3.3V, matching the standard I/O voltage for most mid-range FPGAs and SoCs. The 3V lower edge allows operation on a slightly droopy rail, but don't expect full performance below 3.0V. Differential inputs and outputs are not supported (: No/No) — all I/O are single-ended LVCMOS, which simplifies PCB routing but limits noise immunity on long traces compared to a differential pair. ## Active production, ROHS3, 8-SOIC package No end-of-life notice or successor has been published. The commercial temperature grade (0°C to 70°C) restricts this variant to indoor, temperature-controlled environments. For industrial or automotive use, an industrial-temperature suffix (e.g., CY2303SXI) would be required.","metaTitle":"CY2303SXC Clock Multiplier IC – 166.67 MHz, 3V-3.6V, 8-SOIC","metaDescription":"Infineon CY2303SXC PLL clock multiplier with fanout distribution, 166.67 MHz max, 1:3 ratio, LVCMOS I/O, 8-SOIC.
