CRYSTAL OSCILLATOR/EXTERNAL CLOCK

The ADE9103/ADE9112/ADE9113 requires either an external digital

clock signal or a crystal for operation. A digital clock signal is routed

to the XTALIN pin to clock the ADE9103/ADE9112/ADE9113. The

XTALOUT pin is left floating when XTALIN is provided an external

digital clock source. The requirements for external digital clock

source frequency, duty cycle, and voltage levels are provided in

Table 2.

When a crystal is used as the clock source for the ADE9103/

ADE9112/ADE9113, attach the crystal and the ceramic capacitors,

with capacitance of C1 and C2, as shown in Figure 43. It is not

recommended to attach an external feedback resistor in parallel to

the crystal.
