SiT9003
Up to 12 dB EMI Reduction
Features
Preliminary Information
Low Power Programmable Spread Spectrum Oscillator
The world’s lowest power programmable oscillator with 3.0 mA typical active current
1-110 MHz frequency range. Contact SiTime for frequencies between 80 MHz - 110 MHz
Extremely fast start-up time of 3 ms
<30 ps cycle-cyle jitter
High frequency stability of ±50 PPM, ±100 PPM (when spread is off)
Center spread options: ±0.75%, ±0.5%, ±0.25%
Down spread options: -1.5%, -1%, -0.5%
Up to 12 dB typical EMI reduction
Outstanding mechanical robustness for portable applications
Programmable standby, output enable, or spread off mode
Available in four industry standard packages: 2.5 x 2.0, 3.2 x 2.5, 5.0 x 3.2, 7.0 x 5.0 mm
All-silicon device with outstanding reliability of 2 FIT (10x improvement over quartz-based devices),
enhancing system mean-time-to-failure (MTBF)
• Ultra short lead time
• Ideal for printers, flat panel drivers, PCI, USB, and microprocessors
