SiT8004 for Computing
Low Power Oscillator for DDR and PCI
Features, Benefits and Applications
Lowest power, high frequency oscillator with 6.4mA typical active current
133 MHz, 133.33MHz, 133.33333MHz output frequencies for DDR and PCI applications
LVCMOS/LVTTL compatible output
Excellent frequency stability over temperature, as low as ±20 PPM
Ultra low standby current, 1.2
µA
Standby or output enable modes
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
Drop-in replacement of quartz
Ultra short lead time
All-silicon device with outstanding reliability of 2 FIT (10x improvement over quartz-based devices),
enhancing system mean-time-to-failure (MTBF)
