Order this document by MC12061/D 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 MC12061 CRYSTAL OSCILLATOR · · · Temperature Range = 0 to + 70°C Single Supply Operation: +5.0 Vdc or ­5.2 Vdc Three Outputs Available: 1.
