RIN is the laser noise, integrated over a specified bandwidth, measured relative to average optical power with 12dB return loss. For multimode application, the RIN is better than -117dB/Hz. Note2. TP refers to the compliance point specified in IEEE802.3, section Note3. Optical transition time is the time interval required for the rising or falling edge o f an optical pulse to transition between the 20% and 80% amplitudes relative to the logical 1 and 0 levels.

3 Pin Definition Pin Name Function/Description 1 VEER The negative supply voltage of receiver, connecting to ground plane 2 RD+ Data output of receiver. Compliant for PECL (5V transceiver) or LVPECL (3.3V transceiver) 3 RD- Data output inverted of receiver. Compliant for PECL (5V transceiver) or LVPECL (3.3V transceiver) 4 SD Signal Detection flag. Compliant for PECL (5V transceiver) or LVPECL (3.3V transceiver). When the input optical signal intesity is enough, SD will be High. 5 VCCR The positive supply voltage of receiver, connecting to +5V or +3.3V power plane 6 VCCT The positive supply voltage of transmitter, connecting to +5V or +3.3V power plane 7 TD- Data input inverted of transmitter. Compliant for PECL (5V transceiver) or LVPECL (3.3V transceiver) 8 TD+ Data input of transmitter. Compliant for PECL (5V LVPECL (3.3V transceiver) 9 VEET The negative supply voltage of transmitter, connecting to ground plane Page 3 of 6

4 Block Diagram Recommended Interface Circuit Figure is recommended interface circuit. R1, R2, R3, R4 and R7, R8, R9, R10 form standard Thevenin-equivalent circuits. If the power supply voltage is +5V, all I/O data signals are compliant for PECL. Then R1 = R4 = R6 = R7 = R10 = 130 Ohm, R2 = R3 = R5 = R8 = R9 = 82 Ohm. If the power supply voltage is +3.3V, all I/O data signals are Page 4 of 6

5 compliant for LVPECL. Then R1 = R4 = R6 = R7 = R10 = 82 Ohm, R2 = R3 = R5 = R8 = R9 = 130 Ohm. The SD signal of MTR-03XXXXT is compliant for TTL, then R5 (= 10kOhm) acts as the pull up resistor, and R6 is not connected. L1, L2, C2, C3, C4, C5, C6 form the filter of power supply, L1 = L2 = 1uH. Notice that the inductances should be with low DC impedance, it enables enough current can be achieved. C3 = C6 = 10uF, C1 = C2 = C4 = C5 = C7 = 0.1uF. High-speed circuit design and impedance matching design should be considered. Recommended termination resistor is 50Ohm. Although differential signal transmission is preferred, single terminal signal can be used. Package Outline Page 5 of 6
