Pin Descriptions Pin No. 1,17,20 10, 11,14 16 Function TX GND RX GND TX Vcc * I/O I I I Pin description These pins are the Transmitter ground connections. They should be connected to a low impedance ground plane (0V). These pins are the Receiver ground connections. They should be connected to a low impedance ground plane (0V). This is the power supply pin for the Transceiver part. It should be connected to +3.3V. Recommended power supply decoupling. (See Figure 8) This is the power supply pin for the Receiver part. It should be connected to +3.3V. Recommended power supply decoupling. (See Figure 8) * Both TX Vcc and RX Vcc have been internally connected due to supply of control circuit Vcc. This data input pin modulates the laser diode. When the TD+ input is asserted, the laser diode is turned on. They are internally AC-coupled into an equivalent load of RI differential, as shown in Figure 8. Active high TTL input, with internal 7.4k ohm pull-up resistor to Vcc. Asserting the transmitter disable will deactivate the laser within the assert time. Table 1 indicates the timing of TX_DISABLE. Received Data Out and Inverted Received Data Out are differential serial output from the receiver. These are AC-coupled 100 ohm differential lines which should be terminated with a 100 ohm (differential) at the user SERDES, as shown in Figure 8. AC coupling is done inside the module and is thus not required on the host board. Active high open collector/drain output that indicates a loss-of-signal condition (LOS). When the average optical power received by the module is below the Assert Level, RX_LOS is indicated. Table 1 indicates the timing of RX_LOS. RX_LOS requires a 4.7k to 10k ohm pull-up resistor external to the module, i.e., in the host system Host_Vcc, as shown in Figure 8. The pull-up voltage is between 2.0 V and VccR (VccT) + 0.3 V. Active high open collector/drain output that indicates a fault in the module. This can be failure of the laser diode. Under this condition, TX_FAULT will activate and be latched. And then the laser will be deactivated within the assert time. TX_FAULT also requires a 4.7k to 10k ohm pull-up resistor externally, i.e. in the host system Host_Vcc, as shown in Figure 8. The pull-up voltage is between 2.0 V and VccT (VccR) +0.3V. Toggling TX_DISABLE high for at least t_reset can reset it. See Figure 8 and Figure 5. This module has a serial ID function, which provides information about the transceiver's capabilities, standard interfaces, manufacturer and other information. This function is provided via a two wire serial EEPROM interface. MOD_DEF[0] is connected to ground inside the module. (LOW) MOD_DEF[1] is the serial clock signal input. (SCL) MOD_DEF[2] is the data output/input. (SDA) They should be pulled up with 4.7Kohm -10Kohm resistor on the host board. The pull-up voltage shall be VccT or VccR. The serial ID definitions are as given in the "SFP-MSA" standard. See Figure 9. These pins defined the bandwidth filters. 7pin/9pin setting=[*/*]: [0/0]: Full bandwidth, [1/0]: 1.25Gbps, [0/1]: 622Mbps, [1/1]: 155Mbps These input pins are internally pulled down to GND with 33Kohm resistor. If this function is not used, both pins should be left open or connected to GND.

UQ9-06-008 Ed:1.0 Date:10.Oct.2006 Page 14 of 15 MITSUBISHI (OPTICAL DEVICES) MF-27WXD Series 2.5Gbps SFP TRANSCEIVER MODULE Safety Cautions for Use of Optoelectronic Devices General: Although the manufacturer is always striving to improve the reliability of its product, problems and errors may occur with semiconductor products. Therefore, the user's products are required to be designed with full safety regard to prevent any accidents that result in injury, death, fire or environmental damage even when semiconductor products happen to error. Especially it is recommended to take in consideration about redundancy, fire prevention, error prevention safeguards. And the following requirements must be strictly observed. Warning! 1. Eye safety : Semiconductor laser radiates laser light during operation. Laser light is very dangerous when shot directly into human eyes. Don't look at laser light directly, or through optics such as a lens. The laser light should be observed using the ITV camera, IR-viewer, or other appropriate instruments. 2. Product handling : The product contains GaAs (gallium arsenide). It is safe for regular use, but harmful to the human body if made into powder or steam. Be sure to avoid dangerous process like smashing, burning, chemical etching. Never put this product in one's mouth or swallow it. 3. Product disposal : This product must be disposed of as special industrial waste. It is necessary to separate it from general industrial waste and general garbage. Handling Cautions for Optoelectronic Devices 1. General: (1) The products described in this specification are designed and manufactured for use in general communication systems or electronic devices, unless their applications or reliability are otherwise specified. Therefore, they are not designed or manufactured for installation in devices or systems that may affect human life or that are used in social infrastructure requiring high reliability. (2) When the customer is considering to use the products in special applications, such as transportation systems (automobiles, trains, vessels), medical equipments, aerospace, nuclear power control, and submarine repeaters or systems, please contact Mitsubishi Electric or an authorized distributor. 2. Shipping Conditions: (1) During shipment, place the packing boxes in the correct direction, and fix them firmly to keep them immovable. Placing the boxes upside down, tilting, or applying abnormal pressure onto them may cause deformation in the electrode terminals, breaking of optical fiber, or other problems. (2) Never throw or drop the packing boxes. Hard impact on the boxes may cause break of the devices. (3) Take strict precautions to keep the devices dry when shipping under rain or snow. 3. Storage Conditions: When storing the products, it is recommended to store them following the conditions described below without opening the packing. Not taking enough care in storing may result in defects in electrical characteristics, soldering quality, visual appearance, and so on. The main points are described below (if special storage conditions are given to the product in the specification sheet, they have priority over the following general cautions): (1) Appropriate temperature and humidity conditions, i.e., temperature range between 5~30C, and humidity between 40~60 percent RH, should be maintained in storage locations. Controlling the temperature and humidity within this range is particularly important in case of long-term storage for six months or more. (2) The atmosphere should be particularly free from toxic gases and dust. (3) Do not apply any load on the product. (4) Do not cut or bend the leads of the devices which are to be stored. This is to prevent corrosion in the cut or bent part of the lead causing soldering problems in the customer's assembling process. (5) Sudden change in temperature may cause condensation in the product or packing, therefore, such locations should be avoided for storing. Temperature in storage locations should be stable. (6) When storing ceramic package products for extended periods of time, the leads may turn reddish due to reaction with sulfur in the atmosphere. (7) Storage conditions for bare chip and unsealed products shall be stated separately because bare chip and unsealed products require stricter controls than package sealed products. 4. Design Conditions and Environment under Use: (1) Avoid use in locations where water or organic solvents adhere directly to the product, or where there is any possibility of the generation of corrosive gas, explosive gas, dust, salinity, or other troublesome conditions. Such environments will not only significantly lower the reliability, but also may lead to serious accidents. (2) Operation in excess of the absolute maximum ratings can cause permanent damage to the device. The customers are requested to design not to exceed those ratings even for a short time. 5. ESD Safety Cautions: The optoelectronic devices are sensitive to static electricity (ESD, electro-static discharge). The product can be broken by ESD. When handling this product, please observe the following countermeasures: The end of document UQ9-06-008 Ed:1.0 Date:10.Oct.2006 Page 15 of 15 |
