Mouser.
Replace
the standard
32.768
khz t
uning fork crystal in your rea
l time clock (RTC) circuit with this temperature-compensated crystal oscillator (TXCO) and drastically in
crease the ac
curacy of your clock.
The
output of all crystals changes with t
emperature, and this little marvel constantly 'tweaks' itself to maintain
a rock-steady 32.768
khz output. A
n RTC circuit running a normal tuning fork crystal might l
ose/gain up to an hour or more over the course of a year. This one
will get you to within a minute
(
wo
rst case - better accuracy in normal room tem
perature conditions). This is about as accu
rate as you're going to get without upgrading to something like a
satellite
receiver ($$$
) for timekeeping.
Don't be intimidated by
all of the pins - there are only FOUR connections
ne
eded (power, ground, ba
ckup battery, and the 32.768khz clock output).
So simple.
Thanks for looking, and happy bidding!
NOTE: All orders are packed at our ESD station using proper anti-static packaging materials.

Description:
The DS32kHz is a temperature-compensated
crystal oscillator (TCXO) with an output
frequency of 32.768kHz. This device addresses
applications requiring better timekeeping
accuracy, and can be used to drive the X1
input
of most Dallas Semiconductor real-time clocks
(RTCs), chipsets, and other ICs containing
RTCs.
While the DS32kHz is powered by either supply input, the device measures the temperature every 64 seconds and
adjusts the output frequency. The device requires four pins for operation: VCC, GND,
VBAT, and 32kHz. Power is applied through VCC and GND, while VBAT is used to maintain the
32kHz output in the absence of power. Once every 64 seconds, the DS32kHz measures the temperature
and
adjusts the output frequency. The output is accurate to ±2ppm (±1 min/yr) from 0°C to +40°C.
Features:
- Accurate to ±1 Minute/Year (0°C to +40°C)
- Battery Backup for Continuous Timekeeping
- VBAT Operating Voltage: 2.7V to 5.5V with VCC
Grounded
- VCC Operating Voltage: 4.5V to 5.5V
- No Calibration Required
- Low-Power Consumption
