IF Counter Structure
The LC72135M IF counter is a 20-bit binary counter that accepts an IF input from either the HCTR pin (for FM or AM IF
counting) or the LCTR/I1 pin (for AM IF counting). The result of the count can be read out serially through the DO pin
starting with the MSB.
The IF frequency (Fc) is measured by determining how many pulses were input to an IF counter in a specified
measurement period, GT.
Fc =
(C = Fc
×
GT)
C: Count value (number of pulses)
1. IF Counter Frequency Calculation Examples
When the measurement period (GT) is 32 ms, the count (C) is 53980 hexadecimal (342400 decimal):
IF frequency (Fc) = 342400
÷
32 ms = 10.7 MHz
When the measurement period (GT) is 8 ms, the count (C) is E10 hexadecimal (3600 decimal):
IF frequency (Fc) = 3600
÷
8 ms = 450 kHz
