Clock generators and PLLs synthesize precise reference frequencies for digital systems — providing CPU clocks, serializer/deserializer reference clocks, Ethernet PHY clocks, and USB reference frequencies in computers, telecom equipment, networking switches, and test instruments. Our clock generator inventory covers integer and fractional-N PLLs, clock multipliers, spread-spectrum clock generators, and programmable oscillator ICs from Texas Instruments (LMK/CDC series), IDT/Renesas (5P/8T series), Analog Devices (AD95/ADF4 series), Silicon Labs (Si53xx), and Cypress/Infineon — supporting output frequencies from 1 kHz to 1 GHz+, multiple output configurations, and differential (LVPECL/LVDS/HCSL) and single-ended (CMOS) signal types.
Programmable clock generators (Si5351, CDCM61002) and spread-spectrum clock ICs for EMI reduction are frequently in high demand, while legacy integer-N PLLs for telecom and video timing remain critical for aging infrastructure. Welllinkchips stocks these clock ICs and can source discontinued timing devices needed for legacy system maintenance.
