SiT8503
High Performance 200-1000 KHz Oscillator
■ Features, Benefits and Applications
■ 200 - 1000 kHz frequency range (contact SiTime for <200 kHz)
■ Frequency stability as low as ± 20 PPM
■ LVCMOS/LVTTL compatible output
■ Typical current consumption of 5.7 mA in active mode
■ 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
■ All-silicon device with outstanding reliability of 2 FIT, 10x improvement over quartz-based devices,
enhancing system MTBF
■ Outstanding mechanical robustness for portable applications
■ Ultra short lead time
■ Ideal for consumer electronics, audio applications
