Description
Clk-
B8
Input
Xtal g or Negative Clock Input.
Typically connected along with
XTAL_D to an external surface mount AT cut crystal. Can also be con-
figured as a frequency input when using an external crystal oscillator.
When configured as a frequency input, typically connected to Ground
with a 10 pF capacitor.
Clk+
B9
Input
Xtal d or Positive Clock Input.
Typically connected along with
XTAL_G to an external surface mount AT cut crystal. Can also be con-
figured as a frequency input when using an external crystal oscillator.
When configured as a frequency input, is typically connected to an ex-
ternal Temperature Compensated Crystal Oscillator (TCXO) through
an Alternating Current (AC) coupling capacitor.
32kHz_CLKI
