DESCRIPTION
DC2073A demo board features Linear Technology's SOT23
packaged silicon oscillators. The DC2073A demo board is
available in eleven different options; DC2073A-A through
DC2073A-K. These eleven options provide for the evalu-
ation of resistor-set oscillator ICs and fixed frequency
ICs (Table1).
