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...).

1.
Resonator characteristics given by the crystal/ceramic resonator manufacturer.
2.
For CL1 and CL2 it is recommended to use high-quality ceramic capacitors in the 5-pF to 25-pF range (typ.) designed for
high-frequency applications and selected to match the requirements of the crystal or resonator. CL1 and CL2, are usually the
same size. The crystal manufacturer typically specifies a load capacitance which is the series combination of CL1 and CL2.
PCB and MCU pin capacitance must be included when sizing CL1 and CL2 (10 pF can be used as a rough estimate of the
combined pin and board capacitance).
3.
The relatively low value of the RF resistor offers a good protection against issues resulting from use in a humid
environment, due to the induced leakage and the bias condition change. However, it is recommended to take this point into
account if the MCU is used in tough humidity conditions.
4.
tSU(OSC4M) is the typical start-up time measured from the moment VDD_IO is powered (with a quick VDD_IO ramp-up from 0
to 3.3V (<50
s) to a stabilized 4MHz oscillation is reached. This value is measured for a standard crystal resonator and it
can vary significantly with the crystal/ceramic resonator manufacturer.
