Data Input
(1) D0 (LSB) to D13 (MSB): Divisor data
FMIN uses D0 to D13 and AMIN uses D4 to D13.
Sample calculation
x
FM 100 kHz steps (f
ref
= 100 kHz)
FM VCO = 100.7 MHz (FM RF = 90.0 MHz, IF = 10.7 MHz)
Divisor =
100.7 MHz (FM VCO) ÷ 100 kHz (f
ref
) = 1007
→
3EF
(HEX)
y
AM 10 kHz steps (f
ref
= 10 kHz)
AM VCO = 1450 kHz (AM RF = 1000 kHz, IF = 450 kHz)
Divisor =
1450 kHz (AM VCO) ÷ 10 kHz (f
ref
) = 145
→
91
(HEX)
(2) T0 and T1 are LSI test bits and both should be set to 0.
(3) B0 to B2, TB: Band data
Time base data
Note:
*
: Determined by R0 to R3. See item (4) on next page.
: Don’t care
TB: 8 Hz
