32 768khz crystal datasheet pdf

The most important thing to keep in mind is that the capacitor should be tight tolerance with an appropriate dielectric material one that isnt highly temperature dependent, such as np0c0g. There are other values that will do this all multiples of 32768, but this value is very common. Not applicable parameters minimum typical maximum units notes frequency 32. With a heat resistant plastic package, the abs25 has reflow capability and extended temperatures of. Also, page 20 of the c1111 datasheet that you linked to says 1218pf is the range to use for the 32. Datasheet the isl12057 device is a lowpower, realtime clock that is pin compatible and functionally equivalent to maxim ds37 with clockcalendar and alarm function. Tolerance typically 5 ppm to 30 ppm all of these crystal parameters are given by the crystal data sheet but can be also measured at the real crystal using, for example, crystal impedance bridge, a vector voltmeter, or a network analyzer.
