DESCRIPTION
LTC1799, LTC6900, LTC6905,
LTC6905-XXX, LTC6906, LTC6907
LTC6908 SOT23 Silicon Oscillators
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).
