C210 CLKIN Configuration
Capacitor C210 is used to input an external clock signal. In default
settings the on-board quartz oscillator is used for generating the
microcontroller's clock speed (C210 not populated). As an alternative
an external clock signal can be connected to the controller pin XIN via
phyCORE connector pin X700A1. This requires removal of the
on-board quartz oscillator and populating C210 with a 100p/50V
capacitor.
Note:
Because of the oscillator properties, C210 should not be closed when
using the on-board quartz oscillator. This can have a negative effect on
the stability of the quartz oscillation!
If an external clock input via X700A1 is required, the on-board quartz
oscillator must be removed.
The following configurations are possible:
