IF Counter Structure
The LC72136N IF counter is a 20-bit binary counter. The result of the count can be read out serially, MSB first, from the
DO pin.
IF frequency (Fc) measurement consists of determining how many pulses enter the IF counter in a specified
measurement time (GT).
Fc =
(C = Fc
× GT)
C: count value (number of pulses)
Sample IF Counter Frequency Calculations
1. For a measurement time (GT) of 32 ms and a count value (C) of 53980 (hexadecimal), which is 342,400 (decimal)
IF frequency (Fc) = 342,400 ÷ 32 ms = 10.7 MHz
2. For a measurement time (GT) of 8 ms and a count value (C) of E10 (hexadecimal), which is 3600 (decimal)
IF frequency (Fc) = 3600 ÷ 8 ms = 450 kHz
