6.10.4.1 Clock Specifications

The AWR1843AOP requires external clock source (that is, a 40-MHz crystal or external clock) for initial boot and as a reference for an internal APLL hosted in the device. An external crystal is connected to the device pins. Figure 6-7 shows the crystal implementation.

GUID-EBD4FA8D-0862-4402-B468-0FCD34A9F649-low.gifFigure 6-7 Crystal Implementation
Note:

The load capacitors, Cf1 and Cf2 in Figure 6-7, should be chosen such that Equation 1 is satisfied. CL in the equation is the load specified by the crystal manufacturer. All discrete components used to implement the oscillator circuit should be placed as close as possible to the associated oscillator CLKP and CLKM pins.

Equation 1. GUID-ABEB21DF-C4ED-46A1-8A95-1E534ADF5429-low.gif

Table 6-5 lists the electrical characteristics of the clock crystal.
