version 2.0/03.2007 dimensions OV-7604-C7 low power clock oscillator 32.768 khz all dimensions in mm typical description: this very small smd ceramic package has been specially designed to combine the 32.768 khz crystal unit with the cmos-based oscillator circuit. ultra low power consumption, as low as 300 na, are made possible through 32.768 khz tuning-fork-crystals and sophisticated cmos- circuitry. for pick-and-place equipment, the parts are available in 12 mm tape: 7? (178 mm) reel with 3'000 oscillators 10? (254 mm) reel with 7'000 oscillators 13? (330 mm) reel with 14'000 oscillators xtal integrated solution ultra miniature smt ceramic pack. ind. and ext. temperature ranges package height 1.0 mm very low power consumption very tight frequency tolerance low aging high shock and vibration resistante package: recommended solder pad: block diagram: output control osc 32.768 khz crystal clkout clkoe v dd gnd 4 2 1 3 pin connections top view: pin connection 1 clkout frequency output 2 gnd ground 3 clkoe clk output enable 4v dd power supply voltage 100% leadfree, rohs - compliant #1 #2 #4 #3 pin 1 index production date code 7604 m 708 a 1 part designation 1,5 0,5 0,5 3,2 1,0 max. 0,75 0,75 0,5 1,7 1,0 1,0 2,0 0,8 0,8 0,4 o v - 7 6 0 4 - c 7 . i n d d 1 2 5 . 0 5 . 2 0 0 7 1 0 : 3 2 : 1 6
