4.1.19 Power output
Power can be supplied to external devices or modules. The 8-pin connector
(Receptacle, mini fit 8 Way, Molex) JP16 provides several voltages and has the
following pinout:
Pin
number
-12V 1
+12V 2
+5V 3
+3.3V 4
GND 5
GND 6
GND 7
Key 8
Table 2 : Power out pinout
Connector position 8 is filled to prevent plugging in the power input
cable (the connectors are the same type). A modified plug (pin 8
removed) must be used for power output.
4.1.20 JTAG
A single JTAG chain connects all 4 TIM sites and the JTAG in & out connectors. This
chain is used with the TI Code Composer Studio software suite. Although in essence
it is a chain, the chain exists internally to a Xilinx CPLD. The CPLD drives and
receives signals to the 4 TIM sites independently. This allows JTAG clock
frequencies in excess of 30MHz to work reliably.
The JTAG-out (JTAG2) connector can be connected to the JTAG-in (JTAG1) connector
of other SMT148FX, thus extending the chain (see cable
All JTAG chaining and TIM bypass is performed within the CPLD.
