Figure 11 - Time-constant Circuit
A digital alternative to the RC-time-constant circuit is presented in Figure 12. The circuit in Figure 12 can be used to
generate a steady lock signal. The circuit monitors the MT9043’s LOCK pin, as long as it detects a positive pulse
every 1.024 seconds or less, the Advanced Lock output will remain high. If no positive pulse is detected on the
LOCK output within 1.024 seconds, the Advanced LOCK output will go low.
