USB Connector

The SC5511A uses a mini-USB Type B connector (for USB communication) and a micro-HDMI (for SPI or
RS-232 communication, depending on the version ordered) to communicate with the device. The USB
port uses 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 3. Pinout of the SC5511A USB communication connector.

Signal Connections

All signal connections (ports) on the SC5511A are SMA-type. Exercise caution when fastening cables to
the signal connections. Over-tightening any connection can cause permanent damage to the device.
RF OUT This port outputs the tunable RF signal from channel 1 of the source. The
CHANNEL 1 connector is SMA female. The nominal output impedance is 50 Ω.
RF OUT This port outputs the tunable RF signal from channel 2 of the source. The
CHANNEL 2 connector is SMA female. The nominal output impedance is 50 Ω.
REF OUT This port outputs the internal 10 MHz reference clock. The connector is SMA
female. This port is AC-coupled with a nominal output impedance of 50 Ω.
