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.
