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.

Power

Power sequence on will be executed over 4 States:

  • State 1 IDLE: Wait until LTM_1V_IO0 (1V), LTM_1V_IO1 (1V) and LTM_1V5_4V_IO1 (4V) is available.
  • State 2 PS1: Enables 1V8, 3V3FMC and VADJ. Wait until PG_1V8 (1.8V), PG_3V3 (3.3V) and PG_FMC_VADJ (FMC VADJ) is available.
  • State 3 PS2: Wait until LTM_1V5_4V_IO0 (1.5V) is available
  • State 4 RDY: All power on

State machine restart power sequencing, if on of the power good signal are lost.

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

S1-4S1-3S1-2Voltage
OFFOFFOFF3.3V
OFFOFFON2.5V
OFFONOFF1.9V
OFFONON1.5V
ONOFFOFF1.25V
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 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.

1FAN1 RPSFAN1 Revolutions per second

FAN FMC

Is enabled/disabled with FMC preset signal (PCB REV02 only).

Button

Button is debounced and controls PROG_B signal from FPGA.

LED

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

WEEE

Information for users within the European Union in accordance with Directive 2002/96/EC of the European Parliament and of the Council of 27 January 2003 on waste electrical and electronic equipment (WEEE).

Users of electrical and electronic equipment in private households are required not to dispose of waste electrical and electronic equipment as unsorted municipal waste and to collect such waste electrical and electronic equipment separately. 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.

Trenz Electronic is registered under WEEE-Reg.-Nr. DE97922676.
