Our Technology

These properties are used  for clock synchronization, demodulation, frequency synthesis, clock multipliers, and signal recovery from a noisy communication channel. Since the year 2000, a single integrated circuit can provide a complete PLL building block, and have output frequencies from a fraction of a hertz up to many gigahertz.

​

Crystal/MEMS oscillators are one of the most common of all electronic components. They are everywhere—in your radio, TV, PC, laptop, controller, and communications equipment, to name a few. This is because they are unique in working at a single frequency—they are highly stable and drift-free, setting the time reference for all electronics systems sold.

​

The use of PLLs as the signal generator for a crystal or MEMS resonator brings huge advantages to clock and timing industry. Rather than having to inventory a different frequency resonator for each application, the crystal oscillator company is able to purchase just one crystal resonator, combine that with Glacier’s PLL products and then simply program the output frequency and feature set desired by their customer. This dramatically shortens leadtimes and minimizes over purchases of resonators and die. The die are also semicustomized in older applications.

 

Outside of the highest performance applications, PLL oscillators perform as well or better than older single frequency oscillators. Lower lead-time, less inventory, equivalent power and performance, PLL’s are the best way to fill out an oscillator product line.
