Baseband Connections

The SC5313A has 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 Ω. 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 Ω terminator. All baseband connectors are MCX female.

Communication Connection

The SC5313A uses a mini-USB Type B connector for primary communication with the device using the
standard USB 2.0 protocol found on most host computers. The pinout of this connector, viewed from
the front of the module, is listed in Table 1.

The user can also communicate with the device through the micro-HDMI port. Depending on the
product version ordered, this connector provides either the SPI or RS-232 communication path. The
pinout of this connector, viewed from the front of the module, is listed in Table 2.
