What is Screened External Clock?
The ADCs used on ATST364 have a “minimum clock frequency” specification of 300 MHz, i.e. if the external clock signal is lower than 300 MHz, the ADC may not be able to make proper measurement. Typical problem is that user will see glitches in the output data. Many customer applications need the ATST364 to work with external clock frequencies lower than 300 MHz.
Fortunately, we have seen that many ATST364 work perfectly down to 100 MHz clock rate. We have developed a process by which we can “screen” the ATST364 board for external clock operation down to 100 MHz, i.e. select ATST364 that works down to 100 MHz clock frequency.
If customer purchases the screened External Clock Upgrade, we will test the ATST364 at external clock frequency down to 100 MHz to make sure that it works before shipping it to the customer. If the ATST364 we are testing does not work down to 100 MHz, we will not ship it to the customer and use a different unit that does work down to 100 MHz. The screened option (ATST364-006) includes ATST364-005, i.e. if you purchased the screened option, you do not have to purchase the other.
