Low power miniature quartz crystal oscillators
Hermetically sealed in a high reliability 4-pad ceramic surface mount housing, the CXOLP series oscillators offer fast start-up of 1-ms typical, tight calibration tolerance of ±25 ppm and high shock resistance of 10000-g typical.
Available at frequencies from 1.0 to 8.5 MHz and available for operation over the military temperature range from −55 to +125°C, the oscillators feature low current consumption of 55 µA at 1 MHz making them ideal in low power hand-held products. Frequency stability over temperature specifications are ±10- to ±50-ppm for commercial (-10 to +70°C), ±20- to ±100-ppm for industrial (-40 to +85°C) and ±40- to ±100-ppm for military. Output load is 5 pF (CMOS) and supply voltage is 1.8- to 3.3-V ±10%.
Additional specifications include rise/fall times of 5.5 and 5.0 ns respectively (10% to 90%), duty cycle of 40% minimum and 60% maximum, low ageing of 2 ppm in first year and output enable/disable option available. Package size is 3.2- x 1.5- x 0.95-mm (l x w x d) and the low power oscillators can be supplied in tray pack or on 12-mm tape reels. Maximum process temperature is 260°C for 20 seconds.
