Baseband Connections

The SC5312A and SC5313A have four baseband output ports comprised of differential in-phase (I+ and I-)
and differential quadrature (Q+ and Q-) outputs. Nominal differential output impedance is 100  The
demodulator can also be configured for single-ended or differential IF output. When configured for
single-ended operation, it is recommended to terminate the other half of the differential pair using a 50
 terminator. All baseband connectors are MCX female.

Device LED Indicators

These are two LED indicator lights for the device, and their functions are listed in Table 1 and
Table 2.

Mini-USB Connection

The SC5313A uses a mini-USB Type B connector for primary communication with the device using the
standard USB 2.0 protocol (full speed) found on most host computers. The pinout of this connector,
viewed from the front, is shown in the following table.
Rev 2.1 | SC5312A & SC5313A
This port accepts an RF signal ranging from 400 MHz to 6 GHz.
This port can be used as an alternate path for system-level
calibration. The connector is SMA female. The nominal input
impedance is 50 .
This port accepts a tunable LO signal from an external source
to drive the demodulator. The connector is SMA female. This
port is AC-coupled with a nominal input impedance of 50 .
Maximum input power is +10 dBm.
