Powerful Slow External Clock
ATS460 uses ADC converters that cannot operate below 10 MHz clock frequency. For customers who have clocks that are slower than 10 MHz, AlazarTech has designed the powerful Slow External Clock.
Slow External Clock must be a 3.3 Volt LVTTL signal. Sine wave or other types of signals are not allowed.
In this mode, the ADCs run at 125 MHz internal frequency, but the hardware detects a rising (or falling) edge of the incoming Slow External Clock and latches one sample point for each edge. This results in a sampling jitter of ±8 ns, which may or may not be acceptable in a particular application.
