2 application literature application note 1035 (versatile link) - av02-0730en package and handling information the compact versatile link pack age is made of a fl ame- retardant material and uses the same pad layout as a standard, eight-pin dual-in-line package. horizontal, vertical, and tilted (30) packages are available. these low profi le versa tile link packages are stackable and are enclosed to provide a dust-resistant seal. snap action simplex, simplex latching, duplex, and duplex latching connectors are off ered with simplex or duplex cables. package orientation performance and pinouts for the horizontal, vertical, and tilted (30) packages are identical. to provide addi tional attachment support for the vertical versatile link housing, the designer has the option of using a self- tapping screw through a printed circuit board into a mounting hole at the bottom of the package. for most applications this is not necessary. package housing color versatile link components and simplex connectors are color coded to eliminate confusion when making con- nections. receiver packages are black and transmitter packages are gray in color respectively. handling versatile link components are auto-insertable. when wave soldering is performed with versatile link compo- nents, the optical port plug should be left in to prevent contamination of the port. do not use refl ow solder processes (i.e., infrared refl ow or vapor-phase refl ow). nonhalogenated water soluble fl uxes (i.e., 0% chloride), not rosin based fl uxes, are recom mended for use with versatile link components. versatile link components are moisture sensitive devices and are shipped in a moisture sealed bag. if the components are exposed to air for an extended period of time, they may require a baking step before the solder ing process. refer to the special labeling on the shipping tube for details. recommended chemicals for cleaning/degreasing alcohols: methyl, isopropyl, isobutyl. aliphatics: hexane, heptane. other: soap solution, 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, avago does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential en- vironmental harm.

5 interlocked (stacked) assemblies (refer to figure 1) horizontal packages may be stacked by placing units with pins facing upward. initially engage the inter - locking mechanism by sliding the l bracket body from above into the l slot body of the lower package. use a straight edge, such as a ruler, to bring all stacked units into uniform alignment. this tech nique prevents potential harm that could occur to fi ngers and hands of assemblers from the package pins. stacked horizontal packages can be disengaged if necessary. repeated stacking and unstack ing causes no damage to individual units. to stack vertical packages, hold one unit in each hand, with the pins facing away and the optical ports on the bottom. slide the l bracket unit into the l slot unit. the straigh t edge used for horizontal package alignment is not needed. stacking horizontal modules stacking vertical modules figure 1. interlocked (stacked) horizontal, vertical and tilted (30) packages tilted (30) module

9 afbr-16xxz transmitter the afbr-16xxz transmitter incorporates a 650 nm led and integrated driver ic in a light gray, nonconductive plastic versatile link housing. its input data is compatible with ttl logic level. this transmitter can operate from dc to 50 mbd with any kind of data pattern using 1 mm polymer optical fiber (pof). within the specifi ed ranges afbr-16x4z and afbr-16x9z devices will support a ber < 10e-9. transmitter electrical characteristics (t a = -40 ? c to +85 ? c, v cct = 3.3 v 5% or 5 v 5%) parameter symbol min typical max unit notes supply current (optical power on) i cct 21 31 ma 1 input voltage C low v il -0.3 0.8 v 2 input voltage C high v ih 2.0 vcc+0.3 v 2 data input capacitance c in 7pf data input resistance r in 2k ? propagation delay t td 30 ns transmitter optical characteristics (t a = -40 ? c to +85 ? c, v cct = 3.3 v 5% or 5 v 5%) parameter symbol min typical max unit notes output optical power (peak), 1 mm pof p n -4.5 -2 +2 dbm 3 output optical power (peak), pcs (200 m) p n -16.5 -13 -9 dbm 3 output optical power (average), off p s -50 dbm extinction ratio er 10 db peak wavelength ? c 630 685 nm rise time (20%C80%) t rt 5ns fall time (20%C80%) t ft 5ns pulse width distortion pwd -3 +3 ns 4, 5 pulse width distortion of fi rst pulse pwd -5 +3 ns 5, 6 notes: 1. for any type of data between dc and 50 mbd. typical value 21 ma for prbs-7 pattern at 25 ? c at 5 v and 50 mbaud. 2. standard ttl compatible input. 3. measured with polished connector end face: after 1 meter 1 mm pof, na = 0.5, or 200 ? m pcs, na = 0.37. 4. pulse width is measured at 50% threshold using a rising edge trigger tested with prbs-7 pattern 5. electrical input pulse width is determined at 1.5 v and du/dt between 1 v and 2 v shall not be less than 1 v/ns. 6. the fi rst pulse is shorter as the led is completely discharged. this helps to mitigate the increase of pulse width of the fi rst pulse of the receiver
afbr-26x4z/25x9z receiver the afbr-26x4z/25x9z receiver consists of a digitalizing ic with integrated photodiode to produce an output level that is compatible with ttl logic. the integrated photodiode and the following amplifi er uses a fully diff erential approach with an active and a passive area for an improved emi performance. within the specifi ed ranges afbr-25x9z and afbr- 26x4z devices will support a ber <10e-9. receiver electrical characteristics (t a = -40 c to +85 c, v cct = 3.3 v 5% or 5 v 5%) parameter symbol min typical max unit notes supply current i ccr 20 30 ma data output voltage C low v ol -0.3 0.4 v 1, 3 data output voltage C high v oh 2.5 v ccr +0.3 v 1, 3 rise time (10%C90%) t rr 5 ns 2, 3 fall time (10%C90%) t fr 5 ns 2, 3 pulse width distortion pwd -4 +4 ns 3, 6, 7, 8, 11 pulse width distortion 1 st to 3 rd pulse pwd init -5 +8 ns 3, 8, 9, 11 propagation delay t rd 30 ns max. initiation time after power up t int 15 ms 12 receiver optical characteristics (t a = -40 c to +85 c, v cct = 3.3 v 5% or 5 v 5%) parameter symbol min typical max unit notes input optical power (peak), 1 mm pof p in -22 +2 dbm 3 input optical power (peak) off -state, 1 mm pof p in _off -40 dbm 3, 10 input optical power (peak), pcs (200 ? m) p in -25 -1 dbm 3 input optical power (peak) off -state, pcs (200 ? m) p in _off -44 dbm 3 optical spectrum range ? 630 685 nm notes: 1. standard ttl output. 2. measured with r l = 50 k ? and c l = 15 pf 3. guaranteed only if optical input signal to the receiver is generated by afbr-16xxz, with ideal alignment to photo diode usin g 1mm pof (na=0.5). 6. optical input signal of 50 mbd, prbs 2 7 -1 pattern and 50% duty cycle. 7. pulse width is measured at 50% threshold using a rising edge trigger and prbs 2 7 -1 pattern. 8. if data rate is below 1mbd the pulse width distortion would be equal to the pulse width distortion of the 1st to 3rd pulses for higher datarates. 9. the threshold of the 1st pulse of a data sequence is diffi cult to adjust and therefore the pulse width distortion up to the 3rd pulse is higher than for all other pulses (worst case for the 1st pulse). this strongly depends on the quality of the rising and falling edge of the optical input. the faster the edges the smaller the pulse width variation. furthermore lower data rates would result in the same issue as all the pulse b ecome 1st pulses. 10. output low for afbr-26x4z and output high for afbr-25x9z. 11. because of optical pulse width spreading, the pwd limits have to be increased by ? 0.1 ns for each 10 m fi ber length. 12. starting point is when supply voltage passes ~2.8 v.
