Description
The SiT1532 is the world’s smallest, lowest power 32 kHz
oscillator optimized for mobile and other battery-powered
applications. SiTime’s silicon MEMS technology enables the
smallest footprint and chip-scale packaging. This device
reduces the 32 kHz footprint by as much as 85% compared to
existing 2.0 x 1.2 mm SMD XTAL packages. Unlike XTALs, the
SiT1532 oscillator output enables greater component
placement flexibility and eliminates external load capacitors,
thus saving additional component count and board space. And
unlike standard oscillators, the SiT1532 features
NanoDrive™, a factory programmable output that reduces the
voltage swing to minimize power.
The 1.2V to 3.63V operating supply voltage range makes it an
ideal solution for mobile applications that incorporate a low-
voltage, batt ery-back-u p source s uch as a coin-cell or s uper -
cap.
SiTime’s MEMS oscillators consist of MEMS resonators and a
programmable analog circuit. Our MEMS resonators are built
with SiTime’s unique MEMS First™ process. A key manufac-
turing step is EpiSeal™ during which the M EMS reson ator is
annealed with temperatures over 1000°C. EpiSeal creates an
extremely strong, cle an, vacuum cham ber that encapsu lates
the MEMS resonat or and ensures the best p erformance and
reliability. During EpiSeal, a poly silicon cap is grown on top of
the resonator cavity, which eliminat es the need for add itional
cap wafers or other exotic packaging. As a result, SiTime’s
MEMS resonator die can be used like any other semicon-
ductor die. One unique result of SiTime’s MEMS First and
EpiSeal manufacturing processes is the capability to integrate
SiTime’s MEMS die with a SOC, ASIC, microprocessor or
analog die within a package to eliminate external timing
components and provide a highly integrated, smaller, cheaper
solution to the customer.
Frequency Stability
The SiT1532 is factory calibrated (trimmed) to guarantee
frequency stability to be less than 10 ppm at room temperature
and less than 100 p pm over the full -40°C to +85° C temper-
ature range. U nlike quart z crystals t hat have a clas sic tunin g
fork parabola temperature curve with a 25°C turnover point,
the SiT1532 temperature coefficient is extremely flat across
temperature. The device maintains less than 100 ppm
frequency stability over the full operating temperature range
when the operating voltage is between 1.5 and 3.63V as
shown in Figur e 2.
Functionality is guaranteed over the 1.2V - 3.63V operating
supply voltag e range. However , frequency stabil ity degrades
below 1.5V an d steadily degr ades as it approach es the 1.2V
minimum supply due to the internal regulator limitations.
Between 1.2V and 1.5V, the frequency stability is 250 ppm
max over temperature.
When measuring the SiT1532 output frequency with a
frequency cou nter, it is important to mak e sure the counter's
gate time is >100ms. The slow frequency of a 32kHz clock will
give false readings with faster gate times.
Contact SiTime for applications that require a wider supply
voltage range >3.63V or lower frequency options as low as
1Hz.
Figure 2. SiTime vs. Quartz
Power Supply Noise Immunity
In addition to eliminating external output load capacitors
common with st andard XTALs, The S iT1532 inc ludes spec ia l
internal power supply filtering and thus, eliminates the need
for an external Vdd bypass-decoupling capacitor. This feature
further simpl ifies the design a nd keeps the footprint as small
as possible. Internal power supply filtering is designed to
reject greater than ±150 mVpp magnitude and frequency
components through 10 MHz.
Output Voltage
The SiT1532 has two outp ut voltag e opti ons. One opti on is a
standard LVCMOS output swing. The second option is the
NanoDrive reduced swing output. Output swing is customer
specific and progr ammed between 200 m V and 800 mV. For
DC-coupled applications, output VOH and VOL are individually
factory programmed to the custom er s’ requirement. VOH
programming range is between 600 mV and 1.225V in 100 mV
increments. Similarly, VOL programming range is between 350
mV and 800 mV. For example; a PMIC or MCU is internally
1.8
V logic compatible, and requires a 1.2V VIH and a 0.6V VIL.
Simply select SiT1532 Nano Drive factor y programming co de
to be “D14” and the correct output thresholds will match the
downstream PMIC or MCU input requirements. Interface logic
will vary by manufacturer and we recommend that you review
the input voltage requirements for the input interface.
For DC-biased NanoDr ive out put conf igur ati on, the mi nimu m
VOL is limited to 350mV and the maximum allowable swing
(VOH - VOL) is 750 mV. For example, 1.1V VOH and 400 mV
VOL is acceptable, but 1.2V VOH and 400 mV VOL is not
acceptable.
When the output is interfacing to an XTAL input that is inter-
nally AC-coupled, the SiT1532 output can be factory
programmed to match the input swing requirements. For
example, if a PMIC or MCU input is internally AC-coupled and
requires an 800 mV swing, then simply choose the SiT1532
NanoDrive pro gramming co de “AA8” i n the part num ber. It is
important to note that the SiT1532 does not include internal
AC-coupling capacitors. Please see the Part Number Ordering
section at the end of the datasheet for more information about
the part number ordering scheme.

Power-up
The SiT1532 s tarts -up to a v alid out put fr equenc y within 30 0
ms (180 ms typ). To ensure the device starts-up within the
specified limit, make sure the power-supply ramps-up in
approximately 10 - 20 ms (to within 90% of Vdd). Start-up time
is measured from the time Vdd reaches 1.5V. For applications
that operate bet ween 1.2V and 1.5V, the st art-up time will be
typically 50 ms longer over temperature.

Calculating Load Current
No Load Supply Current
When calculating no-load power for the SiT1532, the core and
output driver components need to be added. Since the output
voltage swing can be programmed for reduced swing between
250 mV and 800 mV for ultra-low power applications, the
output driver current is variable. Therefore, no-load operating
supply current is broken into two sections; core and output
driver. T he equation is as follows:
Total Supply Current (no loa d) = Idd Core + (65nA/V)(Voutpp)
Example 1: Full-swing LVCMOS
•
Vdd = 1.8V
•
Idd Core = 900nA (typ)
•
Voutpp = 1.8V
Supply Current = 900nA + (65nA/V)(1.8V) = 1017nA
Example 2: NanoDrive™ Red uced Swing
•
Vdd = 1.8V
•
Idd Core = 900nA (typ)
•
Voutpp (D14) = VOH – VOL = 1.1V - 0.4V = 700mV
Supply Curre nt = 900nA + (65nA/V)(0.7V) = 946nA
Total Supply Current with Load
To calculate the total supply current, including the load, follow
the equation listed below. Note the 30% reduction in power
with NanoDrive™.
Total Current = Idd Core + Idd Output Driver (65nA/V*Voutpp)
+ Load Current (C*V*F)
Example 1: Full-swing LVCMOS
•
Vdd = 1.8V
•
Idd Core = 900nA
•
Load Capacitance = 10pF
•
Idd Output Driver: (65nA/V)(1.8V) = 117nA
• Load Current: (10pF)(1.8V)(32.768kHz) = 590nA
•
Total Current = 900nA + 117nA + 590nA = 1.6µA
Example 2: NanoDrive™ Red uced Swing
•
Vdd = 1.8V
•
Idd Core = 900nA
•
Load Capacitance = 10pF
•
Voutpp (D14): VOH – VOL = 1.1V - 0.4V = 700mV
•
Idd Output Driver: (65nA/V)(0.7V) = 46nA
•
Load Current: (10pF)(0.7V)( 32 . 768kHz) = 229nA
•
Total Current = 900nA + 46nA + 229nA = 1.175µA

Manufacturing Guidelines
1)
No Ultrasonic Cleaning: Do not subject the SiT1532 to an ul trasonic cleaning envir onment. Permanent damage or l ong term
reliability issues to the MEMS structure may occur.
2)
Applying board-level underfill (BLUF) to the device is acceptable, but will cause a shift in the frequency tolerance, as specified
in the datasheet electrical table. Tested with UF3810, UF3808, and FP4530 underfill.
3)
Reflow profile, per JESD22-A113D.
