SiT8004
Low Power Oscillator for High Frequency Applications
■ Features, Benefits and Applications
■ Lowest power, high frequency oscillator with 6.3 mA typical active current
■ 125MHz to 150MHz frequency range
■ LVCMOS/LVTTL compatible output
■ Excellent frequency stability over temperature, ±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)
■ Ideal for high frequency applications in networking, storage, computer servers and communications
■ Ideal for high speed protocals: GPON, EPON, Ethernet, SATA/SAS, DDR, PCI
