Free-running on-chip oscillator
Low power relaxation oscillator is a programmable free-running clock generator for coarse clock generation. The design uses a relaxation oscillator with fully integrated elements so no external components are required. The oscillator is designed to have excellent supply noise rejection so it is ideal for use in noisy SoC environments.
特色
- Glitch-free frequency programmability to calibrate out process variations Frequency accuracy as good as 1.5% over voltage, temperature, and process aging after initial calibration
- Low sensitivity to supply voltage and temperature changes
- Fast initial settling time
- Low power operation -- below 100uW and as low as 20uW in some processes
- Low period jitter
- Low area
优势
- No external components required
- Low power
- Stable frequency with good immunity to supply noise
