Inputs
These pins form an oscillator when connected to an external
crystal. Either series or parallel-resonant crystals are
acceptable. Connect directly to the device.

SSC Control (0:1)
LVTTL
Inputs
LVTTL-compatible spread-spectrum control pins. Data on
control pins maintain device control. For spread-spectrum
operation, leave SSC_0 and SSC_1 pins floating (default is
spread ON). To reconfigure the device, simply change the
SSC and the device will respond dynamically.

TEST INPUT
LVTTL
Inputs
Pin is used for test and debug purposes. Is intended to be
left floating in production environment. Programmed as
