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-
