OM-7605-C8 Low Power Clock Oscillator 32.768 kHz DIMENSIONS Package: Recommended Solder Pad: 2,0 1,1 0,7 0,45 0,3 Oscillator with integrated XTAL Very tight frequency tolerance Ultra-miniature ceramic package High shock and vibration resistance Very low power consumption Low aging rate max. 0,70 100% leadfree, RoHS - compliant 0,7 0,45 1,2 0,45 0,7 0,45 0,7 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 350 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 8 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 2 M530A1 3 4 #1 Pin 1 Index #2 Pinout Connection # 1 # 2 # CLKOUT Frequency output CLKOUT GND GND Ground 3 CLKOE CLKOE CLK output enable # 4 VDDVDD Power Supply Voltage ELECTRICAL CHARACTERISTICS AT 25°C: Output Frequency Frequency tolerance 1) F 32.768 kHz ΔF/F +/-20 ppm Supply voltage VDD 1.6 – 5.5 V 2) IDD 0.35 / 0.75 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.)
