... CC 3) Quick Charge In order to hasten the rising time from when power is turned on, the CXA3099N features a quick charge circuit. Therefore, the quick charge circuit eliminates the need to insert a capacitor between the detector output and the LPF as is the case with conventional ICs, but capacitor should be connected to Pin 4 to determine the average signal level during steady-state reception ...
