The combination MG=1, MS=1 is forbidden in any application. It configures the receiver in a test mode where
- DR0/DR1 define the Data Rate (before Manchester coding) as shown onTable 9.
- MG sets the mixer gain:
- MS switches the MIXOUT pin:
- PG sets the phase comparator gain (see “The local oscillator PLL” chapter, page 4):
0 = Normal,
1 = -17dB (typical).
0 = To the mixer output,
1 = To the IF input.
0 = High gain mode,
1 = Low gain mode.
