resistance is based on RF input power. Ratings based on +25 °C.
APPLICATION NOTES
RF input is AC coupled (DC block).
DTCP20231 contains a plastic packaged IC-Ultra Hi-speed comparator.
DTCP20231 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.
DIMENSIONS ARE IN INCHES [MILLIMETERS]
