CRYSTAL OSCILLATORS
Among the above types, a VCXO combined with a TCXO, or a VCXO
combined with an OCXO, is called a VC-TCXO or a VC-OCXO,
respectively. These components have the merit of delicately controlling
their output frequency electrically.

A TCXO is a crystal oscillator with a temperature-sensitive reactance
circuit in its oscillation loop to compensate the frequency-temperature
characteristics inherent to the crystal unit. TOYOCOM TCXOs are
classified into two types. One is a Direct-Type TCXO with a temperature
compensation circuit built into the oscillation loop. The other is an
Indirect-Type TCXO with a temperature compensation circuit outside the
oscillation loop, in which the oscillation frequency is therefore indirectly
controlled. Circuit diagrams of the two types of TCXO are shown in Figs.
1 and 2.
In the case of the TCO-900 series, the temperature compensation circuit is
inserted directly into the crystal oscillation loop as shown in Fig.1. Since a
stable supply of power to the oscillation circuit is unnecessary, the power
consumption and case size of the TCO-900 series are substantially reduced.
Because of these features, the TCO-900 series is widely used as a reference
oscillator for synthesizers in mobile communication systems all over the
world. In particular, the size of the recently developed TCO-5811 is just
0.027cc, which enables the further compact design of mobile terminals.
A VCXO (Voltage Controlled Crystal Oscillator) is a crystal oscillator the
output frequency of which is controlled by adding an external control
voltage via a frequency control input on a variable capacitance component
such as a varactor diode connected in parallel to a load capacitance (CL).
TOYOCOM VCXOs are divided into two types according to Voltage-
Frequency (V-F) characteristic slopes depending on the AFC (Automatic
Frequency Control) input configuration of the VCXO. One is a VCXO
with a positive V-F slope and the other is a VCXO with a negative V-F
slope. Please note that the input voltage of a control circuit will vary
according to the individual type, as shown in Figs. 3 and 4. TOYOCOM's
VCXOs are capable of either, depending on the customer's preference.
TOYOCOM's VCXOs have been increasingly used for broader
applications such as slave oscillators in phased-lock loops, or frequency
modulators.

High frequency stability is obtained in these oscillators by putting the
crystal unit in a high precision oven, which keeps the ambient temperature
constant. Since the temperature inside the oven is adjusted to the zero
temperature coefficient of each crystal oscillator, high stability is obtained.
Because an AGC (Automatic Gain Control) circuit is provided in the
oscillation circuit of the TCO-613, -615, and -632 series, high stability of
output frequency (±5 ~ ±10X10–9 / –10 ~ +60ºC)is being realized and its
short-term frequency stability and frequency vs. supply voltage
characteristic are excellent. These oscillators are therefore widely used as a
source of standard frequency in satellite navigation systems such as the
SSNN and various measurement systems.

SPXO delivers excellent frequency stability without the necessity of
temperature compensation and frequency control.
SPXO with a high frequency range –TCO-3110 Series– is a direct
oscillation crystal oscillator that employs an HFF (High Frequency
Fundamental) crystal developed by TOYOCOM. It is mainly installed in
transmission equipment.

Crystal clock oscillations are high-frequency devices that supplyclock signals to variou electronic circuits. They can be used inlead-electrode and surface mounting applications over frequencyranges from 1.5MHz to 140MHz. Housing crystal units that consistof AT or BT cut fundamental or overtone and their oscillationcircuit in the same package, our crystal clock oscillators aredesigned and manufactured to provide a stable output of signalswhen the set voltage is applied.Generally, when customers buy crystal units and use them in thieroscillation circuits, they first need to provide analog settings priorto the installation. These include the settings of load capacitance,oscillation allowance, and variations in characteristics due to
temperature changes. With Toyocom's crystal clock oscillators,these settings are already provided by us, so their output signalscan directly control TTL and CMOS ICs. This shortens designprocesses for customers and contributes to standardizing parts tobe used. Our crystal clock oscillators also feature a VCXOfunction and a Try-state function. The VCXO function enablescontrol of output frequencies with external control voltage,whereas the Try-state feature maintains the output terminals athigh impedance levels by outputting signals with control siganlswhile the power is supplied.For further details about individual products, please refer to theirspecification sheets.

• Crystal Clock oscillators are high-frquency devices incorporatingcrystal units and oscillation circuits. In handling these products, itis critical to observe the following directions:
• When designing circuits and printed circuit boards incorporatingthese products, install a bypass capacitor in the order of 0.1µF atthe nearest possible location between the grounding and theoscillator's power terminal.
• These products include semiconductor circuits and very thincrystal blanks. When providing ultrasonic cleaning, werecommend that the user provide assessments prior to thecleaning, as cleaning might damage the crystal blanks dependingon how the oscillator is installed and how the cleaning is provided.Also, pay attention to possible impacts on the oscillator both inmechanical and thermal aspects.
• Recomended storage period is 6 months or shorter at 15-35°C,humidity of 75%RH or less.
• Take measures against static electricity during transportation,storage and use.
• Crystal Clock oscillators use semiconductors in their internaloscillation circuits with the semiconductor terminals directlyconnected to the oscillators. Therefore, do not apply voltage toother terminals when power is not provided to the power terminal.Also, do not apply power greater than the rated power voltage toterminals other than the power terminal.
