If the clock input to any module fails, the module will automatically switch back to its internal clock and will continue to
operate at full power even in current sharing systems.. The CLK IN and CLK OUT signals are AC coupled.
Temperature Monitoring (TEMP MON)
The TEMP MON pin provides an indication of the module’s internal temperature. The voltage at the TEMP MON pin is
proportional to the temperature of the module baseplate at 10mV per qC, where:
The temperature monitor signal can be used by thermal management systems (e.g. to control a variable speed fan). It can
also be used for overtemperature warning circuits and for thermal design verification of prototype power supplies and
heatsink.
