POWER CONNECTIONS
Power for the board is supplied by three banana jacks, SLAC_VCC, GND and AUX_VCC. The
SLAC_VCC powers the QLSLAC device only. AUX_VCC powers the on-board voltage regulator,
VR1, pull-up resistors and the LED. Two jumpers allow for the power to be supplied from either
SLAC_VCC or AUX_VCC via the voltage regulator. Refer to "Jumpers JDVCC and JAVCC" on page
2-4 for more information.

ANALOG INTERFACE AND SLIC DEVICE CONTROL
The Analog Interface consists of the four pairs of analog transmit and receive BNC connectors and
are designed to be connected to the four-wire interface of the SLIC Device Evaluation Board. These
connector pairs are labeled VIN1 and VOUT1, VIN2 and VOUT2, VIN3 and VOUT3, and VIN4 and
VOUT4. The table below gives a short description of how the signals connect to each other.
Digital control of the SLIC Device Evaluation Board is provided through the H1, H2, H3, and H4
headers. These headers provide external (off board) control of the SLIC device, and monitor the
DETECT signal when the SLIC Device Evaluation Board has its own control select jumpers set to
the EXTERNAL control position. (Refer to the SLIC evaluation board documentation for more
information on control selection.) The table below lists the pin assignments of the SLIC device
control connectors.
Note:
The "x" denotes the specific channel (1–4) of the signal. The QLSLAC device generates the E1 signal when
so programmed. If the E1 signal is not generated by the QLSLAC device, the signal is pulled High.
