32 kHz Real-Time Clock Crystal Oscillator Operation
Table 142. Recommended Crystal Oscillator Specifications(20 MHz Operation)
Figure 52
oscillator with an external 32 kHz, fundamental-mode, parallel-resonant crystal. The rec-
ommended crystal specifications are listed in
board layout should add no more than 4 pF of stray capacitance to either the RTC_X
RTC_X
to decrease loading.
An on-chip MOS resistor sets the crystal drive current limit. This configuration does not
require an external bias resistor across the crystal. An on-chip MOS resistor provides the
biasing.
