data sheet 1340-type lightwave receiver january 2000 2 lucent technologies inc. description (continued) the sonet/sdh versions of the receiver are fully compliant with the latest issue of telcordia technolo- gies gr-253- core and the most recent issues of itu recommendations g.957 and g.958. the 1340-type receiver requires only a single 5 v power supply for operation. all versions of the receiver are characterized for operation over the case operating range of C40 c to +85 c at the appropriate data rate for each version. manufactured in a 20-pin dip, the receivers use a pla- nar, rear illuminated ingaas pin photodetector that allows these receivers to be used at wavelengths from 1.1 m m to 1.6 m m. the photocurrent output of the pin detector is ampli?ed and converted to a voltage by a silicon ampli?er. a silicon quantizer provides additional signal ampli?cation, data threshold detection, and pecl data outputs. the incoming optical signal is cou- pled into the receiver through a 62.5 m m core multi- mode ?ber pigtail. the outer jacket diameter of the pigtail is 900 m m. the receiver can be ordered with the pigtail terminated in an fc/pc, sc, or st ? optical con- nector. other connectors are available on special order. see your lucent account representative for ordering conditions and information. the receiver has differential pecl data outputs and, depending on the version selected, either differential pecl link status ?ag or complementary cmos link status ?ag outputs. the link status ?ag outputs indicate the presence or absence of a minimum acceptable level of optical input signal. 1-414(c) figure 1. block diagram filter si preamplifier ingaas pin si comparator filter v cc flag data optional v pin flag data
lucent technologies inc. 3 data sheet january 2000 1340-type lightwave receiver description (continued) to help ensure high product reliability and customer satisfaction, lucent is committed to an intensive quality program that starts in the design phase and proceeds through the manufacturing and shipping process. opto- electronics subsystems are quali?ed to lucent internal standards using mil-std-883 test methods and pro- cedures and sampling techniques consistent with tel- cordia technologies requirements. the 1340 receiver quali?cation program meets the intent of telcordia technologies tr-nwt-000468 and ta-tsy-000983. application information the 1340 receiver is a highly sensitive ?ber-optic receiver. although the data outputs are digital logic lev- els (pecl), the device should be thought of as an ana- log component. when laying out the printed-wiring board (pwb), the 1340 receiver should be given the same type of consideration one would give to a sensi- tive analog component. at a minimum, a double-sided printed-wiring board with a large component-side ground plane beneath the receiver must be used. in applications that include many other high-speed devices, a multilayer pwb is highly recommended. this permits the placement of power and ground connections on separate layers, which helps minimize the coupling of unwanted signal noise into the power supplies of the receiver. layout considerations a ?ber-optic receiver employs a very high-gain, wide- bandwidth transimpedance ampli?er. the ampli?er detects and ampli?es signals that are only tens of na in amplitude. any unwanted signal currents that couple into the receiver circuitry cause a decrease in the receivers sensitivity and can also degrade the perfor- mance of the receivers loss of signal (flag) circuit. to minimize the coupling of unwanted noise into the receiver, route high-level, high-speed signals such as transmitter inputs and clock lines as far away as possi- ble from the receiver pins. if this is not possible, then the pwb layout engineer should consider interleaving the receiver signal and ?ag traces with ground traces in order to provide the required isolation. noise that couples into the receiver through the power supply pins can also degrade device performance. the application schematics, figures 35, show recom- mended power supply ?ltering that helps minimize noise coupling into the receiver. the bypass capacitors should be high-quality ceramic devices rated for rf applications. they should be surface-mount compo- nents placed as close as possible to the receiver power supply pins. the ferrite bead should have as high an impedance as possible in the frequency range that is most likely to cause problems. this will vary for each application and is dependent on the signaling frequen- cies present on the application circuit card. surface- mount, high-impedance beads are available from sev- eral manufacturers. data and flag outputs the data outputs of the 1340 receiver are driven by open-emitter npn transistors which have an output impedance of approximately 7 w . each output can pro- vide approximately 50 ma maximum output current. due to the high switching speeds of ecl outputs, transmission line design must be used to interconnect components. to ensure optimum signal ?delity, both data outputs (data and d a t a ) should be terminated identically. the signal lines connecting the data outputs to the next device should be equal in length and should have matched impedances. controlled impedance stripline or microstrip construc- tion must be used to preserve the quality of the signal into the next component and to minimize re?ections back into the receiver. excessive ringing due to re?ec- tions caused by improperly terminated signal lines makes it dif?cult for the component receiving these sig- nals to decipher the proper logic levels and may cause transitions to occur where none were intended. also, by minimizing high frequency ringing due to re?ections caused by improperly designed and terminated signal lines, possible emi problems can be avoided. the applications sections in the signetics * ecl 10k/100k data manual or the national semiconductor ? ecl logic databook and design guide provide excellent design information on ecl interfacing. * signetics is a registered trademark of signetics corp. ? national semiconductor is a registered trademark of national semiconductor corporation.
data sheet 1340-type lightwave receiver january 2000 4 lucent technologies inc. data and flag outputs (continued) the flag and fla g outputs of the oc-3/stm-1 155 mbits/s version of the 1340 receiver are pecl logic levels driven by open emitter transistors with the same characteristics as the data outputs. these out- puts must be properly terminated in order to obtain the correct logic levels. since the flag function is basi- cally a dc switch that indicates the loss of optical input signal, it can be interfaced to much slower ttl or cmos logic circuits. the circuit shown in figure 2 provides one example of how to create a ttl logic output from the pecl flag output signal. the outputs of the lt1016 are ttl-com- patible and provide both true and inverted logic levels. the q output of this circuit will be a ttl high (>2.5 v) when the 1340 is receiving an optical signal greater than the flag switching threshold and will be a ttl low (<0.4 v) whenever the optical signal is absent or is below the flag switching threshold. the flag and fla g outputs of the oc-12/stm-4 and 1.25 gbits/s receivers are 5 v ttl logic level compatible. the flag output is provided directly by the comparator ic. how- ever, the flag output is derived from the fla g output through an inverter. excessive loading of the fla g out- put can cause the flag output to malfunction. 1-800(c).a * part available from linear technology corporation of milpitas, ca 95035. figure 2. converting pecl flag outputs to ttl 11 12 14 10 k w ttl (true) ttl (inverted) lt1016* 1340 r x flag flag +5 v +5 v 10 k w + q q
data sheet january 2000 1340-type lightwave receiver lucent technologies inc. 5 pin 10 pin 10 on the 1340-type receiver is a not internally connected (nic) pin. this de?nition allows the 1340 to be used in most customer 20-pin receiver module applications. customers printed-wiring boards that are designed with ground, +5 v, C5 v, or no connection to this pin are all acceptable options. for those applica- tions that require monitoring the photocurrent of the pin photodetector for power monitoring purposes, there are versions of the 1340 that require +5 v or C5 v applied to pin 10. check tables 4 and 5 for ordering information. recommended user interface the 1340 receiver is designed to be operated from a 5 v power supply and provides raised or pseudo-ecl (pecl) data outputs. figures 3 and 4 show two possi- ble application circuits for the 1340 receiver. figure 3 represents an application for the version with pecl flag outputs while figure 4 shows a possible applica- tion for the version with the ttl-compatible flag outputs. in both instances, the data outputs are terminated with a thvenin equivalent circuit, which provides the equiv- alent of a 50 w load terminated to (v cc C 2 v). a single 50 w resistor terminated to (v cc C 2 v) could also be used, but this requires a second power supply. other methods of terminating ecl-type outputs are discussed in the references previously mentioned. figure 5 shows an example of a circuit that can be used to interface the pecl outputs of the 1340 receiver with a device which requires true, negative voltage ecl inputs. the 100314 is an ecl line receiver and is shown here only as an example to demonstrate this coupling procedure. the data lines are terminated in a 50 w equivalent impedance but are ac-coupled to the 100314. the capacitive coupling isolates and per- mits level shifting of the positive data outputs of the receiver to the proper negative level required by the inputs of the 100314. the v bb output of the 100314 provides the reference voltage required to center the voltage swing of the data signals around the input switching threshold of the 100314. the thvenin equivalent of the 166 w and 250 w resistor pair is 100 w , which, in parallel with the 100 w resistor con- nected to v bb , results in a 50 w equivalent impedance for the load on each of the data lines. alternatively, if there is no v bb reference available, a second pair of 166 w /250 w resistor networks could be used on the data lines on the 100314 side of the coupling capacitor. * 50 w to (v cc C 2) v. ? data and data are 50 w impedance transmission lines; both lines can be ac- or dc-coupled into the next device. ? fair-rite products corporation part number 2743037447 or equivalent. note: all unused outputs must be terminated as shown. all resistors are 1/8 w, thin-?lm, ceramic chips. all capacitors are 25 vdc, ceramic x7r, or equivalent. figure 3. interfacing to the 155 mbits/s 1340 receiver 1340 0.1 ? 0.1 ? 124 w 9 7 11 12 14 0.1 ? 0.1 ? 82 w 82 w 2.2 ? ? flag* 124 w 124 w flag* +5.0 v 82 w 82 w 124 w data ? data ? ferrite bead 1-500(c).d
