Electrical Specifications
Sometimes at starting or during data receiving, some bit data group (composed of sixteen consecutive
signal waves belonging to the same frequency band) may be affected by interference noise, this causing
the number of its waves to vary and the consequent synchronous discrepancy between “RXDT–“ and
“RXCK” signals. To correct this discrepancy, the sixteenth dividing counter of frequency incorporated in
this RF-module IC for “RXCK” clock signal generation are always reset at the moment at which any
internal demodulated bit data changes from “0” to “1” so that “RXCK” terminal signals are forcibly output at
L-level with the timing shown below. This correction is made automatically regardless of whether or not
receiving signals are properly input. (The frequency dividing counter is not reset at bit data change from
“1” to “0”.)
