15.10 Zero Latency Filter

In high-speed operation, and under proper circuit

conditions, it is possible for the comparator output to

oscillate. This oscillation can have adverse effects on

the hardware and software relying on this signal.

Therefore, a digital filter has been added to the

comparator output to suppress the comparator output

oscillation. Once the comparator output changes, the

output is prevented from reversing the change for a

nominal time of 20 ns. This allows the comparator

output to stabilize without affecting other dependent

devices. Refer to Figure 15-3.

Output waiting for TZLF to expire before an output change is allowed

TZLF has expired so output change of ZLF is immediate based on

comparator output change
