Frequency Synthesizer Circuit
(2) Multiplier
Clock fVCO is a multiplied up version of clock fPIN (See Figure 25). The relationship between fVCO and
the clock input to the multiplier (fPIN) from the prescaler is as follows:
fVCO = fPIN x 2(n+1) where n is the decimal equivalent of the value loaded in FSM.
Setting FSM to 255 disables the multiplier and fVCO = fPIN.
Note:
n must be chosen such that fVCO equals 48 MHz.

Frequency Synthesizer Multiply Register (FSM)
(3) Divider
Clock fSYN is a divided down version of clock fVCO (See Figure 26). The relationship between fSYN and
the clock input to the divider (fVCO) from the multiplier is as follows:
fSYN = fVCO / 2(m+1) where m is the decimal equivalent of the value loaded in FSD.
Setting FSD to 255 disables the divider and fSYN = fVCO.
