NOTES:
(30 kHz STEPS)
1. Receiver 1st I.F. = 45 MHz, low side injection; Receiver 2nd I.F. = 11.7 MHz, low side injection.
2. Duplex operation with 45 MHz receiver/transmit separation.
3. fR = 7.5 kHz; ÷ R = 2048.
4. Ntotal = N 64 + A = 27501 to 28166; N = 429 to 440; A = 0 to 63.
5. MC145158–2 may be used where serial data entry is desired.
6. High frequency prescalers (e.g., MC12018 [520 MHz] and MC12022 [1 GHz]) may be used for higher frequency VCO and fref
implementations.
7. The φR and φV outputs are fed to an external combiner/loop filter. See the Phase–Locked Loop — Low–Pass Filter Design page for
additional information. The φR and φV 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.
