Functional Description

SFP Control

  • Input Signal LA03_N sets all four SFP RX modes (LA03_N=HIGH sets RS0 signals LOW for 1000BASE-SX, LA03_N=LOW sets RS0 signals HIGH for 10GBASE-SR)1
  • Input Signal LA04_P sets all four SFP TX modes (LA04_P=HIGH sets RS1 signals LOW for 1000BASE-SX, LA04_P=LOW sets RS1 signals HIGH for 10GBASE-SR)1
  • Output Signals LA05_N, LA06_N, LA07_N and LA08_N indicate signal loss of SFP A, B, C and D respectively (HIGH indicates signal loss).
  • Output Signals LA05_P, LA06_P, LA07_P and LA08_P indicate SFP A, B, C and D module absent (HIGH when module physically absent).
  • Output Signal LA04_N  is HIGH when at least one of the four SFPs indicate Laser fault.
  • Input LA03_P HIGH sets for all SFPs where the module is physically available (MDEF0_i is LOW) the TX_DIS signal to LOW.1

1Inverted control as we can not enable weak pulldown in MAX10, we use weak pullup. E.g. TX are all ENABLED at default power up, so the card is working with no FMC LA pin driven.

I2C

  • LA00_P, LA00_N and LA01_P form a "three wire I2C" bus with separate data in and output.
  • LA01_N, LA02_P and LA02_N are used as selector for the MUX.

LED

LED is used as Status LED and is on if at least on SFP is connected.

JTAG

MAX10 JTAG for programming is always enabled and accessible via the FMC connector, pin header J3 and test points.

Trenz Electronic GmbH herewith declares that all its products are developed, manufactured and distributed RoHS compliant.

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.
