2 Functinal Descriptin Receiver Sectin Design The receiver sectin fr the AFCT-5964TLZ/TGZ/ATLZ/ ATGZ/NLZ/NGZ cntains an InGaAs/InP pht detectr and a preamplifier munted in an ptical subassembly. This ptical subassembly is cupled t a pstamp/ decisin circuit n a circuit bard. The design f the ptical assembly is such that it prvides better than 14 db Optical Return Lss (ORL). The pstamplifier is ac cupled t the preamplifier as illustrated in Figure 1. The cupling capacitrs are large enugh t pass the SONET/SDH test pattern at 155 Mb/s withut significant distrtin r perfrmance penalty. If a lwer signal rate, r a cde which has significantly mre lw frequency cntent is used, sensitivity, jitter and pulse distrtin culd be degraded. Figure 1 als shws a filter functin which limits the bandwidth f the preamp utput signal. The filter is designed t bandlimit the preamp utput nise and thus imprve the receiver sensitivity. These cmpnents will reduce the sensitivity f the receiver as the signal bit rate is increased abve 155 Mb/s. The device incrprates a phtdetectr bias circuit. This utput must be cnnected t V CC and can be mnitred by cnnecting thrugh a series resistr (see Applicatin Sectin). Nise Immunity The receiver includes internal circuit cmpnents t filter pwer supply nise. Hwever under sme cnditins f EMI and pwer supply nise, external pwer supply filtering may be necessary (see Applicatin Sectin). The Signal Detect Circuit The signal detect circuit wrks by sensing the level f the received signal and cmparing this level t a reference. The SD utput is +3.3 V TTL.

Yu can cntact them thrugh yur Avag Technlgies sales representative. The fllwing infrmatin is prvided t answer sme f the mst cmmn questins abut the use f the parts. Optical Pwer Budget and Link Penalties The wrst-case Optical Pwer Budget (OPB) in db fr a fiber-ptic link is determined by the difference between the minimum transmitter utput ptical pwer (dbm avg) and the lwest receiver sensitivity (dbm avg). This OPB prvides the necessary ptical signal range t establish a wrking fiber-ptic link. The OPB is allcated fr the fiberptic cable length and the crrespnding link penalties. Fr prper link perfrmance, all penalties that affect the link perfrmance must be accunted fr within the link ptical pwer budget. Electrical and Mechanical Interface Recmmended Circuit Figures 6a and 6b shw recmmended dc and ac cupled circuits fr deplying the Avag Technlgies transceivers in +3.3 V systems. Data Line Intercnnectins Avag Technlgies AFCT-5964TLZ/TGZ/ATLZ/ATGZ/ NLZ/NGZ fiber-ptic transceivers are designed t cuple t +3.3 V PECL signals. The transmitter driver circuit regulates the utput ptical pwer. The regulated light utput will maintain a cnstant utput ptical pwer prvided the data pattern is reasnably balanced in duty cycle. If the data duty cycle has lng, cntinuus state times (lw r high data duty cycle), then the utput ptical pwer will gradually change its average utput ptical pwer level t its preset value.

Figure 6b. Recmmended ac cupled interface circuit The AFCT-5964TLZ/TGZ/ATLZ/ATGZ/NLZ/NGZ have a transmit disable functin which is a single-ended +3.3 V TTL input which is dc-cupled t pin 13. In additin these devices ffer the designer the ptin f mnitring the laser dide bias current and the laser dide ptical pwer. The vltage measured between pins 17 and 18 is prprtinal t the bias current thrugh an internal 10 resistr. Similarly the ptical pwer rear facet mnitr circuit prvides a pht current which is prprtinal t the vltage measured between pins 19 and 20, this vltage is measured acrss an internal 200 resistr. As fr the receiver sectin, it is internally AC-cupled between the preamplifier and the pstamplifier stages. The actual Data and Data-bar utputs f the pstamplifier are DC-cupled t their respective utput pins (pins 9, 10). The tw data utputs f the receiver shuld be terminated with identical lad circuits. Signal Detect is a single-ended, +3.3 V TTL utput signal that is DC-cupled t pin 8 f the mdule. Signal Detect shuld nt be AC-cupled externally t the fllw-n circuits because f its infrequent state changes. 8 The designer als has the ptin f mnitring the PIN pht detectr bias current. Figure 6b shws a resistr netwrk, which culd be used t d this. Nte that the pht detectr bias current pin must be cnnected t V CC. Avag Technlgies als recmmends that a decupling capacitr is used n this pin. Pwer Supply Filtering and Grund Planes It is imprtant t exercise care in circuit bard layut t achieve ptimum perfrmance frm these transceivers. Figures 6a and 6b shw the pwer supply circuit which cmplies with the small frm factr multisurce agreement. It is further recmmended that a cntinuus grund plane be prvided in the circuit bard directly under the transceiver t prvide a lw inductance grund fr signal return current. This recmmendatin is in keeping with gd high frequency bard layut practices.

9 Package ftprint and frnt panel cnsideratins Avag Technlgies transceivers cmply with the circuit bard Cmmn Transceiver Ftprint hle pattern defined in the current multisurce agreement which defined the 2 x 10 package style. This drawing is reprduced in Figure 7 with the additin f ANSI Y14.5M cmpliant dimensining t be used as a guide in the mechanical layut f yur circuit bard. Figure 8 shws the frnt panel dimensins assciated with such a layut. Eye Safety Circuit Fr an ptical transmitter device t be eye-safe in the event f a single fault failure, the transmitter must either maintain eye-safe peratin r be disabled. The AFCT-5964TLZ/TGZ/ATLZ/ATGZ/NLZ/NGZ is intrinsically eye safe and des nt require shut dwn circuitry. Signal Detect The Signal Detect circuit prvides a de-asserted utput signal when the ptical link is brken (r when the remte transmitter is OFF). The Signal Detect threshld is set t transitin frm a high t lw state between the minimum receiver input ptical pwer and -45 dbm avg. input ptical pwer indicating a definite ptical fault (e.g. unplugged cnnectr fr the receiver r transmitter, brken fiber, r failed far-end transmitter r data surce). The Signal Detect des nt detect receiver data errr r errr-rate. Data errrs can be determined by signal prcessing ffered by upstream PHY ICs. Electrmagnetic Interference (EMI) One f a circuit bard designer s fremst cncerns is the cntrl f electrmagnetic emissins frm electrnic equipment. Success in cntrlling generated Electrmagnetic Interference (EMI) enables the designer t pass a gvernmental agency s EMI regulatry standard and mre imprtantly, it reduces the pssibility f interference t neighbring equipment. Avag Technlgies has designed the AFCT-5964TLZ/TGZ/ATLZ/ATGZ/NLZ/NGZ t prvide excellent EMI perfrmance. The EMI perfrmance f a chassis is dependent n physical design and features which help imprve EMI suppressin. Avag Technlgies encurages using standard RF suppressin practices and aviding prly EMI-sealed enclsures. Avag Technlgies OC-3 LC transceivers (AFCT-5964TLZ/ TGZ/ATLZ/ATGZ/NLZ/NGZ) have nse shields which prvide a cnvenient chassis cnnectin t the nse f the transceiver. This nse shield imprves system EMI perfrmance by effectively clsing ff the LC aperture. The recmmended transceiver psitin, PCB layut and panel pening fr these devices are the same, making them mechanically drp-in cmpatible.

10 Recmmended Slder and Wash Prcess The AFCT-5964TLZ/TGZ/ATLZ/ATGZ/NLZ/NGZ are cmpatible with industry-standard wave slder prcesses. Prcess plug This transceiver is supplied with a prcess plug fr prtectin f the ptical prt within the LC cnnectr receptacle. This prcess plug prevents cntaminatin during wave slder and aqueus rinse as well as during handling, shipping and strage. It is made f a high-temperature, mlded sealing material that can withstand +85 C, and a rinse pressure f 110 lbs per square inch. The prcess plug shuld nly be used nce. After remving it frm the transceiver, it must nt be used again as a prcess plug; hwever, if it has nt been cntaminated, it can be reused as a dust cver. Recmmended Slder fluxes Slder fluxes used with the AFCT-5964TLZ//TGZ/ATLZ/ ATGZ/NLZ/NGZ shuld be water-sluble, rganic fluxes.

11 Regulatry Cmpliance The Regulatry Cmpliance fr transceiver perfrmance is shwn in Table 1. The verall equipment design will determine the certificatin level. The transceiver perfrmance is ffered as a figure f merit t assist the designer in cnsidering their use in equipment designs. Electrstatic Discharge (ESD) There are tw design cases in which immunity t ESD damage is imprtant. The first case is during handling f the transceiver prir t munting it n the circuit bard. It is imprtant t use nrmal ESD handling precautins fr ESD sensitive devices. These pre cautins include using grunded wrist straps, wrk benches, and flr mats in ESD cntrlled areas. The secnd case t cnsider is static discharges t the exterir f the equipment chassis cntaining the transceiver parts. T the extent that the LC cnnectr receptacle is expsed t the utside f the equipment chassis it may be subject t whatever system-level ESD test criteria that the equipment is intended t meet. Electrmagnetic Interference (EMI) Mst equipment designs utilizing these high-speed transceivers frm Avag Technlgies will be required t meet FCC regulatins in the United States, CENELEC EN55022 (CISPR 22) in Eurpe and VCCI in Japan.
