Linear Technology offers a wide range of phase-locked loops (PLL), clock buffers, clock generators and distributors, silicon oscillators and solid state timing devices. All of these products are fully supported by simulation and design tools that minimize the effort needed to design in these parts. Our very low phase noise integer-N and fractional-N PLLs come with or without an integrated VCO to solve a multitude of local oscillator (LO) problems up to several GHz in frequency. These devises exhibit extremely low spurious output signals, making them suitable for the most demanding applications. Linear Technology’s clock buffers are ideal for converting weak sine waves into low jitter logic levels. These parts can also be used to distribute reference and data converter clocks with minimum additive jitter. We also offer clock generators and distributors that are suitable for producing the low jitter clocks essential to clocking data converters with high signal-to-noise ratio (SNR). These devices introduce a simple but effective method to edge-synchronize multiple outputs from one or more chips. Silicon oscillators and solid state timing devices eliminate the need for crystal or ceramic resonators and timing capacitors. Our devices have been designed for simplicity, accuracy and small size. The solid state nature allows these devices to withstand high shock, vibration and temperature, making them ideal for rugged applications.
