Signal Function
Controls the bias of the frequency tripler;
ROW6[7:0] = 10111111 for normal operation.
Controls the bias of the frequency tripler;
ROW7[7:2] = 011011 for normal operation.
Active high to multiplex the FM detector output into the Q channel baseband amplifier
input.
Active high to power down FM demodulator.
Controls bias of the low noise amplifier;
ROW8[7:5] = 100 for normal operation.
Controls LNA variable gain; ROW8[4:3].
00 is the highest gain.
11 is the lowest gain.
Controls the Q of the IF filter in the IF variable gain amplifier; ROW8[2:0] = 000 for the
highest Q and the highest gain. To reduce Q and widen bandwidth, increment
ROW8[2:0] in the sequence:
001
100
101
111.
Active high enable analog gain control of the LNA.
Active high to power down the temperature sensor.
Active high to enable the temperature sensor.
Enable separate power down for the IF mixer I/Q 0 for normal operation.
