PLLS & Clocks

Years of designing analog front-ends that meet the most demanding performance specifications have allowed Snowbush to develop world-class phase-locked loops, frequency synthesizers and oscillators. Each is available under our flexible business model and is backed with a unique commitment to design support for integration, customization and development of complementary circuit blocks.

SNOWBUSH clock management circuits offer several key technical features and advantages:

Automatic calibration of key analog elements to reduce the impact of process variations and maximize yield
On-chip LDO regulators to increase noise immunity to power-supply and substrate noise
Integrated serial interfaces to allow application specific optimization of PLL parameters
