ML12061

Crystal Oscillator

Legacy Device: Motorola MC12061

The ML12061 is for use with an external crystal to form a crys-

tal controlled oscillator. In addition to the fundamental series mode

crystal, two bypass capacitors are required (plus usual power sup-

ply pin bypass capacitors). Translators are provided internally for

MECL and TTL outputs.

• Frequency Range = 2.0 to 20 MHz

• Operating Temperature Range = 0 to + 70°C

• Single Supply Operation: +5.0 Vdc or –5.2 V DC

• Three Outputs Available:

1.Complementary Sine Wave (600 mVpp typ)

2.Complementary MECL

3.Single Ended TTL
