    General Specs Affected with Higher Temperatures Exceeded in Programmable Clocks

      Usually the Propagation delay, Duty Cycle, Rise and fall time values increase with increase in temperature when you go beyond the temperature grade rating for a Commercial and Industrial grade device. At higher temperatures your transistors will switch slower and your jitter will go up. If you increase your drive strength it may help to reduce jitter since you will have slightly faster edges.     





      Generally the device is not characterized beyond the Industrial temperature range for an Industrial grade device and therefore the specifications like jitter or duty cycle cannot be guaranteed when the temperature range is exceeded. There are chances that the device may run in locking and reliability issues when the temperature range is exceeded and especially when you are working at the higher maximum frequencies. Usually the maximum frequency range is decreased for Industrial temperature grade as compared to commercial temperature grade that can be seen in the respective datasheet.
