■
Features, Benefits and Applications
■ MEMS oscillator with LVCMOS/LVTTL compatible output
■ 1-110 MHz frequency range
■ Frequency stability as low as ±20 PPM
■ Typical current consumption of 6.1 mA in active mode
■ Standby or output enable modes
■ 1.8V, 2.5V - 3.3V supply voltage
TM
■ SoftEdge
configurable rise/fall time for driving higher loads or EMI reduction.
■ 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
■ Ultra short lead time
■ Ideal for consumer electronics: video, set top boxes, HDTV, DVR, scanners, printers, IP camera, etc.
■ Ideal for high-speed serial protocols: Ethernet, USB, SATA, SAS, Fibre Channel, Firewire, PCI Express
