EM MICROELECTRONIC - MARIN SA EM7602 Low Power Clock Oscillator 32768 Hz The World's Smallest Thermo-Compensated Oscillator Dimensions Package: 8.0 1.2 1.2 1.2 Recommended Solder Pad: 3.0 3.8 1.8 1.6 1.0 top view 1.2 1.8 5.0 1.8 1 bottom view 2 4 3 3.6 2.4 max 1.75 side view All dimensions in mm typical Pin Description: 1 = Output enable or NC 2 = Ground 3 = Frequency Output 4 = VDD Description KEY FEATURES Temperature compensation Small SMD ceramic package Low power consumption of 6A Tri state output EM7602 is a low power, low frequency crystal oscillator, with a three times better thermal drift than any conventional tuning fork crystal. It consists of a torsional tuning fork crystal and a CMOS integrated circuit, both assembled in the same package. It is ideal for applications requiring a high timekeeping accuracy over full temperature range. The oscillator are supplied in trays (91 oscillators per tray). For pick-and-place equipment, the parts are available in 16mm tapes: 7" (178 mm) reel with 1000 oscillators 10" (254 mm) reel with 2000 oscillators 13" (330 mm) reel with 4000 oscillators & BENEFITS u u u u u u Save space and components No more matching of quartz with IC Easy PCB design No more trouble with stray capacitors High shock and vibration resistance No need for external trimming components Electrical Characteristics at 25C Output Frequency Frequency tolerance (note 1) Supply voltage Current Consumption (typ/max) (note 2) Duty cycle (min/max) Output voltage (high) (note 3) Output voltage (low) (note 4) Output rise time (max) (note 5) Output fall time (max) (note 5) Start up time Voltage coefficient Turnover temperature (typ) Temperature coefficient (typ) Frequency stability (typ) 0C to +50C -20C to +70C -40C to +85C Note 1: Tighter tolerance on request Note 2: VDD = 3.3V, no load Note 3: IOH = -0.5mA F F/F VDD IDD VOH VOL tr tf tstart T0 F/F Typical Applications Clock drivers for Real Time Clocks Timekeeping in network servers and computers Data logger Electricity, gas and water metering Portable field communication Automotive dashboard High-end mobile phones 32.768 30 2.3 - 3.6 6/10 49/51 VDD - 0.4 0.4 100 100 1 1 20 -0.012 0 to -10 0 to -30 0 to -50 kHz ppm V A % V V ns ns s ppm/V C ppm/C ppm ppm ppm Note 4: IOL = 0.5mA Note 5: CL = 15pF, 10% to 90% Copyright 2003, EM Microelectronic-Marin SA Subject to change without notice Rev.
