APPLICATION NOTES
RF input is AC coupled (DC block).
DTS8031 contains a plastic packaged IC-Ultra Hi-speed comparator.
DTS8031 provides maximum performance with minimum output capacitance. A heavy
capacitive load slows down the TTL output response.
Connect external threshold resistor from Rcntl port to ground.
