IQMS-142 Datasheet, PDF (1/3 Pages) IQD Frequency Products Ltd – MEMS Oscillator Specification

ISSUE 1; June 2016
Description
Ultra low power, ultra small MEMS oscillator at 32.768kHz with
CMOS output in a plastic package. Factory programmable for
a short lead time. Uses SiTime’s MEMS First™ technology.
APPLICATIONS:
Industrial Timekeeping
Industrial Battery Management
Multi-drop 32kHz Clock Distribution
Bluetooth Modules
WiFi Modules
RTC Reference Clock
Frequency Parameters
Frequency
32.768kHz
Frequency Tolerance
±20.00ppm
Tolerance Condition
@ 25°C, post reflow,
Vs=1.5V to 3.63V.
Frequency Stability
±75.00ppm to ±150.00ppm
Ageing
±1ppm max in 1st year @ 25°C
Note: Frequency Tolerance is measured peak-to-peak. Tested
with an Agilent 53132A frequency counter. Due to the low
operating frequency the gate time must be ≥100ms to ensure
an accurate frequency measurement.
Note: Frequency Stability is measured peak-to-peak. Inclusive
of Frequency Tolerance @ 25°C and variations over operating
temperature, supply voltage and load.
Electrical Parameters
Supply Voltage (over Operating Temperature Range): 1.5V to
3.63V
Absolute Maximum Supply Voltage Rating: -0.5 to 3.63V
Absolute Short Duration Supply Voltage (30mins max, over
-40°C to 85°C): 4.0V max
Note: Operating beyond these limits may result in change or
permanent damage to the oscillator.
Operating Current:
Measured with -
TA=25°C, Vs=1.5V to 3.3V and no load: 1μA typ
TA=-10°C to 70°C, Vs=3.63V and no load: 1.9μA max
TA=-40°C to 85°C, Vs=3.63V and no load: 2.2μA max
TA =-40°C to 105°C, Vs=3.63V and no load: 2.8μA max
Power Supply Ramp (over Operating Temperature Range, Vs
ramp-up from 0 to 90%): 100ms max
Start Up Time @ Power Up:
Measured with -
TA=25°C ±10°C: 180ms typ, 300ms max
TA=-40 to 70°C: 450ms max
TA=85°C: 500ms max
TA=105°C: 800ms typ
Operating Temperature Ranges
-10 to 70°C
-40 to 85°C
-40 to 105°C
