The AD9523 is a multifunctional, high speed device that targets
a wide variety of clock applications. The numerous innovative
features contained in the device each consume incremental power.
If all outputs are enabled in the maximum frequency and mode
that have the highest power, the safe thermal operating conditions
of the device may be exceeded. Careful analysis and consideration
of power dissipation and thermal management are critical
elements in the proper application of the AD9523 device.
The AD9523 device is specified to operate within the industrial
temperature range of –40°C to +85°C. This specification is
conditional, however, such that the absolute maximum junction …
