s0369. rev.02. (web) 2014-02-10 pb txc3xghi2x the txc3xghi2x cwdm xfp multi-rate fber optic transceivers with digital diagnostics monitoring functionality provide a quick and reliable interface for 10gbps cwdm applications. the diagnostic functions, alarm and warning features as described in the xfp multi-source agreement (msa) are provided via standard i 2 c serial interface. the transceivers are designed to support the xfp multi-source agreement, and multiple data rates from 9.95gb/s to 11.09gb/s for oc-192, 10g ethernet, 10g fiber channel and fec applications. each transceiver utilizes an electro-absorption modulated laser with an operating wavelength selectable to itu-t standards covering cwdm grid wavelengths. they satisfy class i laser safety requirements in accordance with the u.s. fda/cdrh and international iec-60825 standards. the transceivers connect to standard 30-pad xfp connectors for hot plug capability. this allows the system designer to make confguration changes or maintenance by simply plugging in diferent types of transceivers without removing the power supply from the host system. the transmitter and receiver data interfaces are ac coupled current mode logic (cml). lv-ttl transmitter disable control input and loss of signal output interfaces are also provided. the transceivers operate from +3.3v and +5.0v power supplies over a operating case temperature range of -5c to +70c (commercial), -5c to +85c (extended), or -40c to +85c (industrial). the housing is made of metal for emi immunity. product description ? lead free design & fully rohs compliant ? compliant with xfp msa ? compliant with oc-192/stm-64 ? compliant with itu-t g.709 ? support 10g ethernet applications ? support 10g fiber channel applications ? compatible with itu-t g.695 ? digital diagnostics monitoring ? temperature-stabilized eml transmitter ? low power consumption ? wide case operating temperature range ? distance up to 40km with g.652 fiber features parameter symbol minimum maximum units storage temperature range t st - 40 + 85 c case operating temperature 1 commercial t op - 5 + 70 c extended - 5 + 85 industrial - 40 + 85 supply voltage v cc 3 - 0.2 + 3.6 v v cc 5 - 0.2 + 6.0 operating relative humidity 2 rh 0 85 % input voltage v in 0 v cc v 1 case temperature is measured on top side of xfp module. 2 non condensing absolute maximum ratings multi-rate 10-gigabit cwdm 40km xfp transceivers with digital diagnostics

oplink communications, inc 5 s0369. rev.02. (web) 2014-02-10 txc3xghi2x application notes electrical interface: all signal interfaces are compliant with the xfp msa specifcation. the high speed data interface is diferential ac-coupled internally and can be directly connected to a 3.3v serdes ic. rx_los: the loss of signal circuit monitors the level of the incoming optical signal and generates a logic high when an insufcient photocurrent is produced. tx_dis: when the tx disable pin is at logic high, the transmitter optical output is disabled. (less than -45dbm). p_down: the power down function pin, when held high by the host, places the module in the standby (low power) mode with a maximum power dissipation of 1.5w. this protects hosts which are not capable of cooling higher power modules which may be accidentally inserted. the modules 2-wire serial interface and all laser safety functions must be fully functional in this low power mode. during p_down, the module shall still support the completion of reset interrupt, as well as maintain functionality of the variable power supply. mod_nr: the mod_nr is an output pin that when high, indicates that the module has detected a condition that renders transmitter and or receiver data invalid, shall consist of logical or of the following signals: ? transmit signal conditioner loss of lock ? transmitter laser fault ? receiver signal conditioner loss of lock other conditions deemed valuable to the detection of fault may be added to the mod_nr. the mod_nr output pin is an open collector and must be pulled to host_vcc on the host board. p_down/rst: the negative edge of reset function signal initiates a complete module reset. module behavior during p_down and rst: during execution of a reset (t_init) or while held in power down mode, a module may be unable to determine the correct value for mod_nr and rx_los. these outputs as well as all interrupt related fags, except completion of reset fag, shall be disregarded by the host. when the module completes a reset and is not in power down mode, the module must represent the correct value of both signals on its outputs before posting a completion of reset interrupt to the host. at no time shall a module cause spurious assertion of the interrupt pin. when a host initially applies power to a module with the p_down/rst signal asserted, a module comes up in power down mode. the module shall only assert the interrupt signal pin to inform the host it has completed a reset. the completion of reset fag shall be the only interrupt source fag set during power down mode. the host is expected to clear this interrupt before releasing the module from the power down mode. the transition from power down mode to normal mode will trigger a reset of the module and result in a 2nd module reset and a 2nd reset completion interrupt to the host. power supply and grounding: the power supply line should be well-fltered. all 0.1f power supply bypass capacitors should be as close to the transceiver module as possible. host board termination & coupling r: 4.7 to 10k all caps are in units of f 50 line 50 line 50 line 50 line td - td + rd + rd - as ic / serde s cm l in pu ts cm l ou tp ut s +3 .3 v +3 .3 v +3 .3 v sc l, sd a, mod_abs, mo d_nr , r r r xfp inte rr upt, rx _l os 6 + +5 .0 v + +3.3 v 8, 9 1h coil or fe rr it e in du ctor 1h coil or fe rr it e in du ctor 0.1 10 0. 1 0.1 10 0. 1
