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)
