4/8 MHz crystal / ceramic resonator oscillator (XT1/XT2)
The STR750 system clock or the input of the PLL can be supplied by a OSC4M which is a 4
MHz clock generated from a 4 MHz or 8 MHz crystal or ceramic resonator. If using an 8 MHz
oscillator, software set the XTDIV bit to enable a divider by 2 and generate a 4 MHz OSC4M
clock. All the information given in this paragraph are based on product characterisation with
specified typical external components. In the application, the resonator and the load
capacitors have to be placed as close as possible to the oscillator pins in order to minimize
output distortion and start-up stabilization time. Refer to the crystal/ceramic resonator
manufacturer for more details (frequency, package, accuracy...).
