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 250 nA, are made possible through 32.768 kHz Tuning-Fork-Crystals and sophisticated CMOScircuitry. For pick-and-place equipment, the parts are available in 12 mm tape: 7” (178 mm) reel with 1'000 oscillators 10” (254 mm) reel with 2'500 oscillators 13” (330 mm) reel with 5'000 oscillators BLOCK DIAGRAM: 32.768 kHz CRYSTAL 1 VDD 6 GND 5 CLKOUT OUTPUT CONTROL 10 CLKOE PIN CONNECTIONS TOP VIEW: OSC Product Marking #10 #6 1564 #1 #5 Pin Connection 1 VDD 5 CLKOUT Frequency output 6 GND Ground 10 CLKOE CLK output enable Power Supply Voltage Pins 2, 3, 4, 7, 8, 9 are not connected.
