NOTES:
1. For AM: channel spacing = 5 kHz,
÷
R =
÷
640 (code 100).
2. For FM: channel spacing = 25 kHz,
÷
R =
÷
128 (code 010).
3. The
φ
R and
φ
V outputs are fed to an external combiner/loop filter. See the Phase–Locked Loop — Low–Pass Filter Design page
for additional information. The
φ
R and
φ
V outputs swing rail–to–rail. Therefore, the user should be careful not to exceed the
common mode input range of the op amp used in the combiner/loop filter.

VCO RANGE
NAV: 97.300 – 107.250 MHz
COM–T: 118.000 – 135.975 MHz

R/T
NOTES:
1. For NAV: fR = 50 kHz,
÷
R = 64 using 10.7 MHz lowside injection, Ntotal = 1946 – 2145.
For COM–T: fR = 25 kHz,
÷
R = 128, Ntotal = 4720 – 5439.
For COM–R: fR = 25 kHz,
÷
R = 128, using 21.4 MHz highside injection, Ntotal = 5576 – 6295.
2. A
÷
32/33 dual modulus approach is provided by substituting an MC12015 for the MC12016. The devices are pin equivalent.
3. A 6.4 MHz oscillator crystal can be used by selecting
÷
R = 128 (code 010) for NAV and
÷
R = 256 (code 011) for COM.
4. MC12013 + MC10131 combination may also be used to form the
÷
40/41 prescaler.
5. The
φ
R and
φ
V outputs are fed to an external combiner/loop filter. See the Phase–Locked Loop — Low–Pass Filter Design
page for additional information. The
φ
R and
φ
V outputs swing rail–to–rail. Therefore, the user should be careful not to exceed
the common mode input range of the op amp used in the combiner/loop filter.
