4.2.6 Module (TIM) site
A single module (TIM) site can accept any of Sundance’s FPGA or DSP modules.
All communication ports are routed to the TIM connectors:
 Primary TIM connector (Top): Comport_0 and Comport_3,
 Secondary TIM connector (Bottom): Comport_1, Comport_2, Comport_4, and
Comport_5.
The Comport_3 link is routed by default to the USB 2.0 interface. The remaining
Comports (Comport_1, Comport_2, Comport_4, and Comport_5) are directly
connected (hardwired) to the Sundance Local Bus (SLB) connector.
4.2.7 Sundance Local Bus (SLB) connector
One Sundance Local Bus (SLB) slot is available to add additional I/Os to the SMT111
carrier board.
Forty eight signals from the SLB are connected to four comports on the TIM
connector (Comport_1, Comport_2, Comport_4, and Comport_5).
These are all LVTTL compatible.
As all DSP and FPGA modules that Sundance produce use FPGA device to
communicate via Comports, the SLB signals are therefore available
directly by this FPGA.
4.2.8 Rocket-IO Serial Link (RSL) connector
A pair of Rocket-IO Serial Link (RSL) connectors is provided on the top and bottom
of the SMT111 carrier board.
Four lanes of RSL signals are simply connected from the top (TIM side) to the
bottom. This allows access to the TIM’s underside RSL signals.
4.2.9 External power supply connector
A single 12Vdc power source is needed to power the SMT111 carrier board.
On-board converters provide the following voltages:
+12V 1.0A
-12V 0.75A
+5V 16A
+3.3V 16A
Table 3: Power converters – Ratings
This is sufficient power to provide up to 80Watts of power for FPGA TIMs (if Vcore
is derived from +5V).
