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:

The ML12061 consists of three basic sections: an oscillator
with AGC and two translators. Buffered complementary sine
wave outputs are available from the oscillator section. The
that the higher harmonic levels (greater than the fifth) are
increased when the MECL translator is being driven.
Typically, the MECL outputs (pins 12 and 13) will drive up

Series mode crystals should be used with the oscillator. If it
is necessary or desirable to adjust the crystal frequency, a reac- Noise Characteristics

such an adjustment is necessary, it is recommended that the
crystal be specified slightly lower in frequency and a series
trimmer capacitor be added to bring the oscillator back on fre-
quency. As the oscillator frequency is changed from the natural
resonance of the crystal, more and more dependence is placed
on the external reactance, and temperature drift of the trim-
ming components then affects overall oscillator performance.
The ML12061 is designed to operate from a single supply —
either +5.0 Vdc or –5.2 Vdc. Although each translator has sep-

approximately –122 dB when referenced to a 1.0 Hz
bandwidth. Noise floor is not sensitive to load conditions

2. Close-in noise (100 Hz from oscillator center frequency)
is approximately –88 dB when referenced to a 1.0 Hz
bandwidth.

Frequency Stability
Output frequency of different oscillator circuits (of a given
device type number) will vary somewhat when used with a
given test setup. However, the variation should be within
approximately 0.001ꢀ from unit to unit. Frequency variations
with temperature (independent of the crystal, which is held at
25°C) are small — about –0.08ppm/°C for ML12061 operating
at 8.0 MHz.
