1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.

2. Output is DC coupled.

3. Output is active if E/D is open.

VCXO Functional Description

VCXO Feature: The VTC2 can be ordered with a VCXO function for applications were it will be used in a

PLL, or the output frequency needs fine tune adjustments. This is high impedance, 1 Mohm, input and can

be driven with an op-amp or terminated with adjustable resistors etc. Pin 1 should not be left floating on

the VCXO optional devices.

“No Adjust” Feature: In applications were the VTC2 will be not be used in a PLL, or the output frequency

does not fine tune adjustments, the best device to use would be a VTC2-x0xxx. By using the “no adjust”

option, the circuit is simplified as Vc does not need to adjusted or set to a predetermined voltage and pin 1

should be grounded or left open (but not set to a voltage such as the supply).

NOTE: Additional pads are used to program and adjust the TCXO during manufacturing and should be left

open; do not terminate these to the supply voltage.

Contact Pads are gold over nickel

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional

operation is not implied at these or any other conditions in excess of conditions represented in the

operational sections of this data sheet. Exposure to absolute maximum ratings for extended periods may

adversely affect device reliability.

Handling Precautions

Although ESD protection circuitry has been designed into the the VTC2, proper precautions should be taken

when handling and mounting. VI employs a Human Body Model and a Charged-Device Model (CDM) for

ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on the circuit

parameters used to define the model. Although no industry wide standard has been adopted for the CDM, a

standard HBM of resistance = 1.5kohms and capacitance = 100pF is widely used and therefore can be

used for comparison purposes.

Suggested IR profile

Devices are built using lead free epoxy and can also be subjected to standard lead free IR reflow conditions,

Table 7 shows max temperatures and lower temperatures can also be used e.g. peak temperature of 220C.
