On-board LEDs
There are four LED's available on TE0741 SoM. Two status LED's (D3 and D4) and two user configurable LED's (D1 and D2).
LED | Color | Connected to | Description and Notes |
---|---|---|---|
D1 | Green | LED2 | User configurable LED. |
D2 | Red | LED1 | User configurable LED. |
D3 | Green | DONE | Reflects inverted DONE signal, ON when FPGA is not configured, OFF as soon as PL is configured. This LED will not operate if the the 3.3V power rail is not available. After FPGA configuration the user can use USRACCESSE2 to control Done LED. |
D4 | Green | C_LED | Connected to the system controller indicating status of the module, functionalitly, see: TE0741 CPLD#LED Steadily lit: RESIN pin is kept low. Blinking fast (0.1s on/off): Power sequencing fault (PG_ALL = 0). Blinking at medium speed (0.5s on/off): Power sequencing has completed but the FPGA is not configured (PG_ALL = 1, DONE = 0). Blinking slow (1s on/off): FPGA is configured and board is ready (PG_ALL = 1, DONE = 1). It is also possible to program the System Controller CPLD to connect this LED to FPGA pin named XIO. |
Table 5: Description of the on board LED's.
Note: if FPGA logic toggles DONE pin (to control D3) then D4 will toggle at random, as changing value on DONE will change the blink frequency of D4.
Note |
---|
DONE LED will be ON as long as FPGA is NOT configured and will be OFF when FPGA is configured successfully. If user STARTUPE2 primitive is used in user design then DONE LED is controlled by the user design and can be on/off/blink or have any other functionality defined by the user. |
Clocking
To enable the PLL (phase-locked loop) clock generator Si5338A (U2), CLK_EN-signal (bank 14, pin C26) must be set to high, to activate the 25 MHz reference clock SiT8208AI (U3). The GTX reference clocks 0 and 2 have to be provided by the user on B2B connector JM3.

To enable the voltage supply for the GTX transceivers, namely the Enpirion EP53F8QI voltage regulators U6 and U16, which serve the voltages MGTAVCC (1.0 V) and MGTAVTT (1.2 V), the signal EN_MGT (bank 14, pin H22) have to be set high. The voltage regulators will indicate "Power OK" with signals PG_MGT_1V and PG_MGT_1V2, when reaching stable state.

System Controller CPLD
The system controller System Controller CPLD is used to coordinate the configuration of the FPGA. The FPGA is held in reset (by driving the PROG_B signal) until the power supplies have sequenced. Setting input signal RESIN low will also reset the FPGA. This signal can be driven from the user’s PCB via the board connector.
It is possible for the user to create their own system controller User can create its own System Controller CPLD design using the Lattice Diamond software . Once created the design can be programmed and program it into the device using the JTAG pinsinterface. The JTAGMODE signal JTAGMODE should be set to 3.3V to enable programming mode. For , for normal module operation it should be set to 0V.
The LED that is Green LED D4 (C_LED) connected to the system controller flashes System Controller CPLD is to indicate the state status of the boardmodule. CPLD Firmware, see TE0741 CPLD.

Power and Power-On Sequence
...
Power Consumption
Power Input Pin | Max Typical Current |
---|---|
VIN | TBD* |
3.3VIN | TBD* |
Table 8: Maximum current of power supplies.
* TBD - To Be Determined soon with reference design setup.
Lowest power consumption is achieved when powering the module from single 3.3V supply. When using split 3.3V/5V power supplies, the power consumption (and heat dissipation) will rise, this is due to the DC/-DC converter efficiency (it decreases when VIN/VOUT ratio rises).
...
For highest efficiency of on board DC/-DC regulators, it is recommended to use same 3.3V power source for both VIN and 3.3VIN power rails. Although VIN and 3.3VIN can be powered up in any order, it is recommended to power them up simultaneously.
It is important that all baseboard I/O's Os are 3-stated at power-on until System Controller sets PGOOD signal high (B2B connector JM1, pin 30), or 3.3V is present on B2B connector JM2 pins 10,12 or 91, meaning that all on-module voltages have become stable and module is properly powered up.
See Xilinx datasheet DS182 ( for Kintex7) for additional information. User should also check related baseboard documentation when choosing baseboard design for TE0741 module.
The FPGA 1.0V supply is derived from two regulators operating in a parallel allowing higher load currents. To start the power-on sequence, pin EN1 (JM1-28, enable 1.0V voltage regulators) is by default high. By driving EN1 pin low on base-board the power-on sequence will not start until the EN1 pin is released to high.
A 3.3V supply is also needed and must be supplied from the user's PCB. An output 3.3V supply is available on some of the board connector pins (see section 'Power Rails'). The input 3.3VIN will be switched to the internal 3.3V voltage level after the FPGA 1.0V supply is stable. Than this power supply will be available on the B2B connector pins.
The regulators can be powered from the 3.3V supply or a 5V supply if preferred. The options for powering the board are detailed below.
- Apply 5V to pins VIN and 3.3V to pins 3.3VIN on the board connector
- Apply 3.3V to pins VIN and 3.3VIN on the board connectors.
