IP Cores

Verification IP

RC oscillator 100 MHz

Faststream IP is a low power high-resolution RC oscillator nominally operates at 100 MHz output clock from a 1.2 V supply. No external components are required. The oscillator operates in a voltage range of 1.2 V +/-5% and is qualified over a broad temperature range of -40°C to 85°C. The oscillator has an excellent nominal duty cycle of 50% within +/-10%.

The block is designed on Global Foundries CMOS 55 nm technology.
