IF Counter Structure
The LC72133 IF counter is a 20-bit binary counter. The result, i.e., the counter’s MSB, can be read serially from the DO
pin.
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
