ML12561
Crystal Oscillator
Legacy Device: Motorola MC12561
The ML12561 is the military temperature version of the com-
mercial ML12061 device. It 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 inter-
nally for MECL and TTL outputs.
• Frequency Range = 2.0 to 20 MHz
• Operating Temperature Range TA = –55° to +125°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
