Sources of Parasitic Capacitance
Some attention must be given to the details of the oscillator circuit when used with a crystal resonator.
The PCB traces should be as short as possible. The value of Cload that is specified by the manufacturer
should not be exceeded because of potential start up problems with the oscillator. Additionally, the crystal
should be a parallel resonate-cut and the value of the equivalent series resistance must be less then 90
Ohms.
4.1.2 Using an External Clock Oscillator
Another option for providing the reference clock is to use a single-ended external clock oscillator. When
the gmZAN3 is in reset, the state of the HDATA2/AD2/OSC_SEL is sampled. If the pin is left
unconnected (internal pull-down) then external oscillator mode is enabled. In this mode the internal
oscillator circuit is disabled and the external oscillator signal that is connected to the TCLK pin is routed
to an internal clock buffer. This is illustrated in Figure 8.
