The interfaces act bidirectional, i.e. as input, to read signals from the DUT, or as output,
to control the DUT. The connectors are configurable for user-specific purposes, e.g.
marker or clock signals can be used as trigger signals.
The input and output voltage levels are LVTTL.
Status LEDs
The status LEDs Power, PLL ( P hase L ocked L oop) and TX / RX visually indicate the
status of the CPRI CL ( C ommunication L ink ) as shown in the table.
Power PLL Tx (downlink) / Rx

Note: The TX/RX LEDs refer either to the SFP or to the SMA connection, depending on
the settings of the high speed serial switch in the hardware section.
7.2.4.2 Rear View
The rear panel of the CPRI breakout board contains the user interface for connection with
the R&S
EX-IQ-BOX. Data transmission between the R&S devices is executed via this
interface.
User Interface
TYCO Z-Dok adapter board connector at the rear of the CPRI breakout board. At this
interface, the breakout board is connected directly to the R&S
EX-IQ-BOX by a 168 pin
connector, type TYCO Z-Dok (56 differential pairs).

7.2.4.3 Front View
On the front panel, the CPRI breakout board provides the interfaces to the DUT. The
breakout board supports the optical CPRI link with two SFP modules, and contains a
differential electrical interface, realized by four SMA connectors. In addition, the interfa-
ces Ethernet and RS-232-C provide the input or output for C&M (
C ontrol and M anage-
ment) data. The connectors are labeled on the top on the case.
