Based on the tri-modulus divider concept, up to 17 distinct channels
within the selected operational frequency band by utilizing the same reference crystal
frequency. The selected LO-frequency is described by the formula:
Values for A depend on the frequency band: 302...320MHz...A=3 (TDA5231),
433...450MHz...A=2, 865...870MHz...A=1 (TDA5230)
Values for S are +1, 0, -1
Values for R are 1,2,3,4,5,6,7,8
Example:
A system for 433.92 MHz, having an f
channels:
