Crystal Oscillator
The MC12061 is for use with an external crystal to form a crystal
controlled oscillator. In addition to the fundamental series mode crystal, two
bypass capacitors are required (plus usual power supply pin bypass
capacitors). Translators are provided internally for MECL and TTL outputs.
• Frequency Range = 2.0 to 20 MHz
• Temperature Range = 0 to + 70°C
• Single Supply Operation: +5.0 Vdc or –5.2 Vdc
• Three Outputs Available:
1. Complementary Sine Wave (600 mVpp typ)
2. Complementary MECL
3. Single Ended TTL

time is a function of
crystal series resis-

resistance, the faster
the circuit stabilizes.

All output cables to the scope are equal lengths of 50 Ω coaxial
cable. All unused cables must be terminated with a 50 Ω ± 1%
resistor to ground.
450 Ω resistor and the scope termination impedance constitute
a 10:1 attenuator probe.
