Recommended Pad Layout
Recommended Re"ow Pro!le
Note: TCXO’s are precision subsystems with tolerances measured to 0.01 ppm. Non-Hermetically sealed TCXO’s should not be
subjected to a wash process that will immerse the TCXO in solvents. NO CLEAN is the recommended procedure. The TX-320 series of
TCXO’s has been designed for pick and place re!ow soldering. The suggested re!ow pro"le is shown above. The TCXO may be rel-
fowed one time in the non-inverted state. Typical frequency shift as a result of re!ow is <1.0 ppm per re!ow. VI recommends waiting
at least two hours after re!ow below measuring the unit.

Output Loads
Standard Shipping Method
The Standard ship method for volume production of the TX-320 series is in a matrix tray. These trays are 100ꢀ recyclable. The trays
also o&er the added feature that they can be continuously feed into a pick-n-place machine eliminating the down time required
with tape-n-reel.

Handling Precautions
Although protection circuitry has been designed into this device, proper precautions should be taken to avoid exposure to
electrostatic discharge (ESD) during handling and mounting. VI employs a human-body model *HBM) and a charged-device model
(CDM) for ESD-susceptibility testing and protection design evaluation. ESD voltage thresholds are depending on the circuit param-
eters used to de"ne the mode.
Although no industry-wide standard has been adopted for the CDM, a standard HBM (resistance =1500 ohms, capacitance - 1000
pf) is widely used and therefore can be used for comparison purposes. The HBM ESD threshold presented here was obtained by us-
ing these circuit parameters.
