SiT8003
Low Power Programmable Oscillator
1 - 110 MHz
Features, Benefits and Applications
• The world’s lowest power programmable oscillator with 3.2 mA typical active current
• 1-110 MHz frequency range
• High frequency stability of ±25 PPM, ±30 PPM, ±50 PPM, ±100 PPM
• Extremely fast resume time of 3.5 ms
• Programmable standby or output enable modes
• 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
• Outstanding mechanical robustness for portable applications
• 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 portable applications :portable media players, digital cameras, digital camcorders, portable
navigation device, handheld gaming, cell phone and other handheld applications.
• Ideal for high-speed serial protocols such as: USB 1.1, USB 2.0, SATA, SAS, Fiber Channel,
Firewire, Ethernet, PCI Express, etc
