Operating Conditions
The 403GCX can interface to either 3V or 5V technologies. The range for supply voltages is specied for
ve-percent margins relative to a nominal 3.3V power supply.
Device operation beyond the conditions specied in Table 8 is not recommended. Extended operation
beyond the recommended conditions may affect device reliability:
Note:
These frequencies do not account for
Power Considerations
Power dissipation is determined by operating frequency, temperature, and supply voltage, as well as
external source/sink current requirements. Typical power dissipation is 0.49 W at 38/76 MHz, with an
average 50pF capacitive load.
Derating curves are provided in the section, "Output Derating for Capacitance and Voltage," on page 29.
Recommended Connections
Power and ground pins should all be connected to separate power and ground planes in the circuit board
to which the 403GCX is mounted. Unused input pins must be tied inactive, either high or low.
The IVR pin should be tied to VDD for normal operation.
