Clock & Timing ICs

About Clock & Timing ICs

Every synchronous digital design needs a clock tree, and clock and timing ICs build that tree from the reference oscillator out to every flip-flop. Real-time clocks (RTCs) keep wall-clock time during power loss, PLLs multiply and clean reference frequencies, clock buffers fan out a single source to multiple loads, and programmable clock generators replace banks of discrete oscillators with a single chip. Engineers evaluate jitter, phase noise, output format (LVDS, HCSL, LVCMOS), and supply current. TI, Microchip, SiTime, Renesas, and Maxim Integrated lead the category.
