Clock & Timing ICs

Clock and timing ICs generate, distribute, and synchronize reference frequencies throughout electronic systems. This category covers crystal oscillators and MEMS oscillators, real-time clock (RTC) modules with battery backup, programmable clock generators and buffers, phase-locked loops (PLLs) for frequency synthesis, and classic timer ICs like the 555. Applications include telecom base stations, data-center switches, GPS receivers, and precision instrumentation. Key manufacturers are Silicon Labs, Texas Instruments, Microchip, Maxim Integrated, and Renesas.

Manufacturers listed in Clock & Timing ICs on Circuit Center include Texas Instruments, ECS Inc., Analog Devices, Abracon, ECS, Renesas, Analog Devices (Maxim) and Silicon Labs.
