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. High frequency prescalers may be used for higher frequency VCO and fref
implementations.
6. 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.
