8 figure 6b. recommended ac coupled interface circuit the hfct-5963tl/tg/nl/ng/ atl/atg have a transmit disable function which is a single-ended +3.3 v ttl input which is dc-coupled to pin 8. as for the receiver section, it is internally ac-coupled between the preamplifier and the postamplifier stages. the actual data and data-bar outputs of the postamplifier are dc-coupled to their respective output pins (pins 4, 5). the two data outputs of the receiver should be terminated with identical load circuits. signal detect is a single-ended, +3.3 v ttl output signal that is dc-coupled to pin 3 of the module. signal detect should not be ac-coupled externally to the follow-on circuits because of its infrequent state changes. power supply filtering and ground planes it is important to exercise care in circuit board layout to achieve optimum performance from these transceivers. figures 6a and 6b show the power supply circuit which complies with the small form factor multisource agreement. it is further recommended that a continuous ground plane be provided in the circuit board directly under the transceiver to provide a low inductance ground for signal return current. this recommendation is in keeping with good high frequency board layout practices. package footprint and front panel considerations the agilent transceivers comply with the circuit board ?common transceiver footprint? hole pattern defined in the current multisource agreement which defined the 2 x 5 package style. this drawing is reproduced in figure 7 with the addition of ansi y14.5m compliant dimensioning to be used as a guide in the mechanical layout of your circuit board. figure 8 shows the front panel dimensions associated with such a layout. eye safety circuit for an optical transmitter device to be eye-safe in the event of a single fault failure, the transmitter must either maintain eye-safe operation or be disabled. the hfct-5963tl/tg/nl/ng/ atl/atg is intrinsically eye safe and does not require shut down circuitry. o v ee r x o v cc r x o sd o rd- o rd+ z = 50 ? z = 50 ? z = 50 ? z = 50 ? sd lvttl v cc (+3.3 v) v cc (+3.3 v) rd+ rd- z = 50 ? 1 td- o td+ o t dis o v ee t x o v cc t x o 1 h c2 1 h c1 c3 10 f t x r x 130 ? 130 ? 130 ? 130 ? 100 nf 100 nf 100 nf 100 nf 82 ? 130 ? v cc (+3.3 v) 130 ? 82 ? t dis (lvttl) 23 45 109876 td- td+ note: c1 = c2 = c3 = 10 nf or 100 nf note a: circuit assumes open emitter output note b: when internal bias is provided replace split resistors with 100 w termination * c4 and c5 are optional bypass capacitors for additional low frequency noise filtering. note a note b v cc (+3.3 v) 100 nf 100 nf 82 ? 130 ? v cc (+3.3 v) 82 ? 130 ? c4 * 10 f c5 * 10 f

(0.09) 17.8 (0.700) 2 (0.079) signal detect the signal detect circuit provides a de-asserted output signal when the optical link is broken (or when the remote transmitter is off). the signal detect threshold is set to transition from a high to low state between the minimum receiver input optical power and -45 dbm avg. input optical power indicating a definite optical fault (e.g. unplugged connector for the receiver or transmitter, broken fiber, or failed far-end transmitter or data source). the signal detect does not detect receiver data error or error- rate. data errors can be determined by signal processing offered by upstream phy ics. electromagnetic interference (emi) one of a circuit board designer?s foremost concerns is the control of electromagnetic emissions from electronic equipment. success in controlling generated electromagnetic interference (emi) enables the designer to pass a governmental agency?s emi regulatory standard and more importantly, it reduces the possibility of interference to neighboring equipment. agilent has designed the hfct- 5963tl/tg/nl/ng/atl/atg to provide excellent emi performance. the emi performance of a chassis is dependent on physical design and features which help improve emi suppression. agilent encourages using standard rf suppression practices and avoiding poorly emi-sealed enclosures. agilent?s oc-3 lc transceivers (hfct-5963tl/tg/nl/ng/ atl/atg) have nose shields which provide a convenient chassis connection to the nose of the transceiver. this nose shield improves system emi performance by effectively closing off the lc aperture. localized shielding is also improved by tying the four metal housing package grounding tabs to signal ground on the pcb. though not obvious by inspection, the nose shield and metal housing are electrically separated for customers who do not wish to directly tie chassis and signal grounds together. the recommended transceiver position, pcb layout and panel opening for these devices are the same, making them mechanically drop-in compatible. figure 8 shows the recommended positioning of the transceivers with respect to the pcb and faceplate. package and handling instructions flammability the hfct-5963tl/tg/nl/ng/ atl/atg transceiver housing consists of high strength, heat resistant and ul 94 v-0 flame retardant plastic and metal packaging. recommended solder and wash process the hfct-5963tl/tg/nl/ng/ atl/atg are compatible with industry-standard wave solder processes.
10 process plug this transceiver is supplied with a process plug for protection of the optical port within the lc connector receptacle. this process plug prevents contamination during wave solder and aqueous rinse as well as during handling, shipping and storage. it is made of a high-temperature, molded sealing material that can withstand +85 c, and a rinse pressure of 110 lbs per square inch. the process plug should only be used once. after removing it from the transceiver, it must not be used again as a process plug; however, if it has not been contaminated it can be reused as a dust cover. recommended solder fluxes solder fluxes used with the hfct-5963tl/tg/nl/ng/atl/ atg should be water-soluble, organic fluxes. recommended solder fluxes include lonco 3355-11 from london chemical west, inc. of burbank, ca, and 100 flux from alpha-metals of jersey city, nj. recommended cleaning/degreasing chemicals alcohols: methyl, isopropyl, isobutyl. aliphatics: hexane, heptane other: naphtha. do not use partially halogenated hydrocarbons such as 1,1.1 trichloroethane, ketones such as mek, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride, or n-methylpyrolldone. also, agilent does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm. lc sff cleaning recommendations in the event of contamination of the optical ports, the recommended cleaning process is the use of forced nitrogen. if contamination is thought to have remained, the optical ports can be cleaned using a ntt international cletop stick type (diam. 1.25 mm) and hfe7100 cleaning fluid. figure 8. recommended panel mounting 15.24 (0.6) dimensions in millimeters (inches) 1. figure describes the recommended front panel opening for a lc or sg sff transceiver. 2. sff transceiver placed at 15.24 mm (0.6) min. spacing. 14.22 0.1 (0.56 0.004) 10.16 0.1 (0.4 0.004) detail a top of pcb 1 (0.039) a solder posts 15.75 max. 15.0 min.
