Power Supplies. Bypass to ground with capacitors as close to the pins as possible.
Differential RF Inputs. Accept RF input signal from the SDARS cabled antenna with a 50Ω to
100Ω balun.
Differential First IF Output. Connect an external SAW filter to the IF output.
RF AGC Power-Detector Output. Set the RF AGC attack and decay response times.
IF AGC Control Voltage Input. Input from the filtered PWM AGC control signal from the SDARS
channel-decoder IC.
Differential First IF Input
Overcurrent-Protected Unregulated DC Supply Output. Provides DC power supply to the
antenna module.
Differential Baseband DC Blocking Outputs.
IF2IO- = Inverting in-phase baseband output. AC couple to pin 18.
IF2IO+ = Noninverting in-phase baseband output. AC couple to pin 20.
IF2QO+ = Noninverting quadrature baseband output. AC couple to pin 36.
IF2QO- = Inverting quadrature baseband output. AC couple to pin 38.
Differential Baseband DC Blocking Inputs.
IF2II- = Inverting in-phase baseband input. AC couple to pin 16.
IF2II+ = Noninverting in-phase baseband input. AC couple to pin 19.
IF2QI+ = Noninverting quadrature baseband input. AC couple to pin 37.
IF2QI- = Inverting quadrature baseband input. AC couple to pin 39.
Differential I/Q Baseband Outputs.
IOUT- = Inverting in-phase baseband output.
IOUT+ = Noninverting in-phase baseband output.
QOUT+ = Noninverting quadrature baseband output.
QOUT- = Inverting quadrature baseband output.
Crystal Reference Input
Buffered System Clock Output. Provides clock signal to the SDARS channel-decoder IC.
