fiber optics V23816-N1018-C13, sm 1310nm 2.5 gbd trx oc-48 sonet/sdh telecom links, 2 km 2 description the infineon single mode sonet/sdh transceiver is compliant with the bellcore gr-253, itu-t g.957 and itu-t g.958 specifi- cations. the transmitter section consists of a multiplexer, laser driver, fabry perot laser diode and pigtail single mode fiber. the receiver section consists of a multimode fiber pigtail, pin pho- todiode / preamplifier, postamplifier, clock and data recovery unit and a demultiplexer. the 155 mb/s parallel data interface frees the customer from the concerns of pcb layout at 2.5 gb/s. the pluggable connector mates easily to the customer pcb, and allows the transceiver to be removed prior to any solder reflow or washing of the customer pcb. the transceiver operates from a dual power supply (+3.3 v and +5 v). the transceiver electrical interface is via a 100 pin plugga- ble connector pair. the transmit and receive electrical signals each consist of 16 parallel single-ended data lines which are lvpecl (+3.3 v) compatible, and a differential lvpecl clock. both the transmit input data and clock lines, and the receive outputs data and clock lines, are internally biased and termi- nated. all lines are dc coupled to the interface connector. functional description this transceiver is designed to transmit and receive serial 2.5 gb/s data via singlemode fiber at 1310 nm wavelength. the transmitter accepts 16 lines of parallel electrical data at 155.52 mb/s and a synchronous transmit clock at 155.52 mhz. the data should be updated on the rising edge of the positive transmit clock (txdi55p). the data is multiplexed into a serial data stream at 2488.32 mbit/s. the data follows the sonet bit ordering, where the msb (bit 0) is transmitted first, and the lsb (bit 15) is transmitted last. the laser driver circuit drives the modulation and bias currents of the laser diode. the 2488.32 mbit/s optical data stream is transmitted at 1310 nm wave- length. the laser bias current is controlled by a power control circuit, which regulates the output power over temperature and aging. this is accomplished by using the output of a monitor pin diode (mechanically built into the laser unit) as a feedback signal to prevent the laser power from exceeding the operating limits. the laser driver modulation current is temperature com- pensated to ensure a constant extinction ratio over temperature variations. the laser can be switched off with a logical low signal on the laser shutoff input. the input is internally pulled high, so it can be driven with an open collector ttl interface. the laser bias current is monitored as an analog output voltage at the bias monitor output (ib) pin. the bias monitor can be used to moni- tor the aging of the laser. the receiver accepts an input serial optical data stream at 2488.32 mbit/s. the pin/preamp detects the incoming light and converts it to an electrical current, which is then amplified. the clock and data recovery unit recovers the clock from the input data stream, and aligns the data so it is synchronous with the clock. the data is then demultiplexed directly to 16 lines of parallel data at 155.52 mbit/s, with the msb being bit 0 and the lsb being bit 15. the receiver also outputs a 155.52 mhz synchronous clock. the received data is updated on the falling edge of the positive receive clock (rxqi55p). the rx alarm (flag) indicator will switch active low if there is a loss of optical input signal (los) or if the pll in the clock recov- ery unit is unlocked (lock). the flag output is an open collec- tor ttl, and can be used to monitor the function of the receiver. technical data the electro-optical characteristics described in the following tables are only valid for use under the recommended operating conditions. recommended operating conditions parameter symbol min. typ. max. units operating am- bient tempera- ture (1) t amb 070 c supply voltage 5 v pecl v cc pecl 4.75 5.0 5.25 v supply voltage 3.3 v lvpecl v cc lvpecl 3.04 3.3 3.46 supply current 5 v pecl i cc pecl 350 tbd ma supply current 3.3 v lvpecl i cc lvpecl 1270 tbd total power consumption p tot 6.0 tbd w transmitter data input bit rate 155.52 mbit/s clock input frequency 155.52 mhz clock input frequency tolerance C100 100 ppm clock input duty cycle 40 50 60 % clock input jit- ter tolerance, 10 hz to 20 mhz ui, rms 0.1 rms ui, p-p 1 p-p clock input return loss, 10 mhz to 700 mhz 20 db data input return loss, 10 mhz to 700 mhz 15 db clock and data input high voltage (2) v cc lvpecl C1.165 v cc lvpecl C0.88 v clock and data input low voltage (2) v cc lvpecl C2 v cc lvpecl C1.475 clock input dif- fential swing 0.3 1.3 v p-p data input single ended swing (3) 0.15 0.6 input clock and data rise/fall time 10%C90% t r , t f 1.5 ns
