VECTRON VX-722

VX-722
Dual Frequency HPLL VCXO
VX-722
Description
Features
Applications
The VX-722 is a dual frequency voltage controlled crystal oscillator, VCXO, based upon Vectron’s HPLL high performance phase locked loop
frequency multiplier ASIC that combines key digital synthesis techniques with VI’s proven core analog technology blocks. A standard low
frequency crystal provides the reference to the fractional-n synthesizer so that virtually any frequency between 10MHz and 1200 MHz can
be factory programmed allowing quick turn manufacturing.

See Standard Frequencies and Ordering Information (Pg 8).
Parameters are tested with production test circuit (See Figure 2 for LVCMOS, Figure 3 for LVPECL and figure 4 for LVDS).
Parameters are tested at ambient temperature with test limits guard-banded for specified operating temperature.
Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310.
Parameters are described with waveform diagram below (Figure 5).
Not tested in production, guaranteed by design, verified at qualification.

Figure 6 - Single Resistor Terminaon Scheme
Figure 7 - Pull Up Pull Down Terminaon
Resistor values are typically 120 to 240 ohms for 3.3V operaon and 82 to 120 ohms for 2.5V
operaon.
Resistor values are typically for 3.3V operaon
For 2.5V operaon, the resistor to ground is 62 ohms and the resistor to supply is 240 ohms
There are numerous applicaon notes on terminang and interfacing PECL logic and the two most common methods are a single resistor to ground, Figure 6,
and a pull-up/pull-down scheme as shown in Figure 7. An AC coupling capacitor is oponal, depending on the applicaon and the input logic requirements of
the next stage.
One of the most important consideraons is terminang the Output and Complementary Outputs equally. An unused output should not be le unterminated, and if one of the two outputs is le open it will result in excessive jier on both. PC board layout must take this and 50 ohm impedance matching
into account. Load matching and power supply noise are the main contributors to jier related problems.

Some LVDS structures have an internal 100 ohm resistor on the
input and do not need addional components.

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow
simulation. The VX-722 family is capable of meeting the following qualification tests:
Environmental Compliance

Conditions
Mechanical Shock
MIL-STD-883, Method 2002
Mechanical Vibration

Moisture Sensitivity Level
IPC/JEDEC J-STD-020, MSL1
Handling Precautions
Although ESD protection circuitry has been designed into the VX-722 proper precautions should be taken when handling and
mounting. VI employs a human body model (HBM) and a charged-device model (CDM) for ESD susceptibility testing and design
protection evaluation.

The device has been qualified to meet the JEDEC standard
for Pb-Free assembly. The temperatures and time intervals
listed are based on the Pb-Free small body requirements.
The temperatures refer to the topside of the package,
measured on the package body surface. The VX-722 device is
hermetically sealed so an aqueous wash is not an issue.
