Functional Description

JTAG

CPLD JTAG is selectable with DIP S1-1. (ON FMC, OFF CPLD).

FMC JTAG is accessible with J9 JTAG Pinheader on PCB REV02 and newer only.

FPGA JTAG Bootmode can be set with J11 ( open → QSPI Boot, set → JTAG Boot)

Power

Power sequence on will be executed over 3 States:

  • State 1 IDLE: Wait until LTM_1V_IO0 (1V) and LTM_1V_IO1 (1V) is available.
  • State 2 PS1: Enables 1V5, 1V8, 3V3FMC and VADJ. Wait until PG_1V5(1.5V), PG_1V8 (1.8V), PG_3V3 (3.3V) and PG_FMC_VADJ (FMC VADJ) is available.
  • State 3 RDY: All power is on.

State machine restarts power sequencing, if one of the power good signals is lost. If 1V power signals are '0' state machine jumps back to State 1 - Idle. If other power signals go low, state machine jumps to State 2 - PS1.

FMC VADJ is selectable via DIP S1-2...4.

OFFOFFON2.5V
OFFONOFF1.8V
OFFONON1.5V
ONOFFON1.2V

Note on PCB REV01 it's fix 1.8V.

Reset

PROGRAM_B is controlled by push button after power up sequencing is ready.

CLK

200MHz CLK (DDR3_CLK) is enabled after power up.

I2C

Connect SI5338, LTM and FMC, SODIMM I2C and internal FAN Control to FPGA I2C Bus.

FAN1

I2C Baseaddress: 0x74 (changeable with Firmware update). I2C with 8Bit Register Address with 8Bit Data. I2C CLK currently 20 MHz supported.

FAN FMC

Is enabled/disabled with FMC preset signal (not available on PCB REV01).

Button

Button is debounced and controls PROGRAM_B signal from FPGA.

LED

LED is used as Status LED for power management and programming. Status depends on blink sequence.

By the 13 August 2005, Member States shall have ensured that systems are set up allowing final holders and distributors to return waste electrical and electronic equipment at least free of charge. Member States shall ensure the availability and accessibility of the necessary collection facilities. Separate collection is the precondition to ensure specific treatment and recycling of waste electrical and electronic equipment and is necessary to achieve the chosen level of protection of human health and the environment in the European Union. Consumers have to actively contribute to the success of such collection and the return of waste electrical and electronic equipment. Presence of hazardous substances in electrical and electronic equipment results in potential effects on the environment and human health. The symbol consisting of the crossed-out wheeled bin indicates separate collection for waste electrical and electronic equipment.
