Notes
1.
Calculation of this 14-bit word can be done as follows:
formula for HIGH side injection:
; formula for LOW side injection:
where:
N = decimal value of PLL word
f
RF
= the wanted tuning frequency [Hz]
f
IF
= the intermediate frequency [Hz] = 225 kHz
f
ref
= the reference frequency [Hz] = 32.768 kHz for the 32.768 kHz crystal; f
ref
= 50 kHz for the 13 MHz crystal or
when externally clocked with 6.5 MHz.
Example for receiving a channel at 100 MHz with HIGH side injection:
.
The PLL word becomes 2FCAH.
V
RF
in Fig.5 is replaced by V
RF1
+ V
RF2
. The radio is tuned to 98 MHz (HIGH side injection).
LOW side and HIGH side selectivity can be switched by changing the mixer from HIGH side to LOW side LO injection.
