OM-7604-C7 Low Power Clock Oscillator 32.768 kHz DIMENSIONS Package: Recommended Solder Pad: 3,2 1,0 0,75 0,8 0,4 0,55 0,55 0.70 max 1,5 1,7 0,8 0,75 1,0 100% leadfree, RoHS - compliant Oscillator with integrated XTAL Very tight frequency tolerance High shock and vibration resistance Very low power consumption Low aging rate Miniature ceramic SMT package 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 1'000 oscillators 7” (178 mm) reel with 3'000 oscillators BLOCK DIAGRAM: 4 VDD 2 GND OSC 1 CLKOUT OUTPUT CONTROL 3 CLKOE PIN CONNECTIONS TOP VIEW: 32.768 kHz CRYSTAL Production Date Code #4 #3 Pin 1 Index 1 2 M 530 A 1 7604 #1 Pin 3 4 #2 Part Designation Pinout Connection # 1 # 2 # CLKOUT Frequency output CLKOUT GND GND Ground 3 CLKOE CLKOE CLK output enable # 4 VDD VDD Power Supply Voltage ELECTRICAL CHARACTERISTICS AT 25°C: Output Frequency Frequency tolerance 1) F 32.768 kHz ΔF/F +/-20 ppm Supply voltage VDD 1.2 – 5.5 V 2) IDD 0.3 / 0.5 µA 40 / 60 % Output voltage (high) 3) VOH VDD –0.4 V Output voltage (low) 4) VOL Gnd +0.4 V HCMOS 15 pF IOH 1 mA Current consumption (typ./max.)
