fiber optic components high-speed ttl receiver hfd7000-2xx serie s sensin g and control features ? designed to meet industrial lan (local area network) specifications ? converts optical input into an electrical signal ? typical sensitivity at 660 nm is -21 dbm ? single 5 v supply ? high-speed (dc to 16 mbps) ? metal sma barrel for high mechanical stability ? separate grounding of the barrel provides excellent rfii/emi/esd shielding ? low-cost plastic version (HFD7000-212) available ? pin-compatible with honeywell?s hfd3403 5 mbps receiver warning personal injury do not use these products as safety or emergency stop devices, or in any other application where failure of the product could result in personal injury. failure to comply with these instructions could result in death or serious injury. the hfd7000 series are high-speed optical receivers designed for data transmission in industrial lan applications. the monolithic cmos chip consists of a large area photodiode, pre-amplifier with controlled gain, a post amplifier, a comparator and ttl output stage. the integrated voltage regulator provides easy use in many applications. the chip?s silicon material is optimized for 660 nm operation the on-chip controlled gain provides a wide dyanmic range and low pulse width distortion (pwd). the chip is mounted in a metal to-18 package. in addition, the outer package of the hfd7000-202 has a metal barrel for high mechanical stability and excellent shielding against rfi/emi and esd. this feature allows the receiver to operate in harsh environments. the receiver is designed to work with honeywell?s high-speed 660 nm transmitter, the hfe 7000. for maximum performance of this receiver, a 0.1 f capacitor must be mounted between vcc and ground no more than 3,0 mm [0.12 in] away from the housing. a 4.7 ? resistor in series with vcc increases the filter?s performance. this minimizes external noise and allows the maximum sensitivity to be maintained. warning misuse of documentation ? the information presented in this product sheet is for reference only. do not use this document as a product installation guide. ? complete installation, operation, and maintenance information is provided in the instructions supplied with each product. failure to comply with these instructions could result in death or serious injury.
fiber optic components high-speed ttl receiver hfd7000-2xx series 2 honeywell ? sensing and control operation optical power (photons) from the fiber strikes the active area of the photodiode and is converted to an electrical signal. the current is then converted to a voltage in the transimpedance pre-amplifier. the controlled gain limits the light current created by the photodiode in both the transimpedance pre-amplifier and in the post-amplifier. this avoids a possible overcharge of the amplifier and assures optimum pwd performance. the signal is compared with a threshold defining the system?s sensitivity limit. a final buffer provides a ttl output. the level sensitive behavior makes the system robust with resp ect to the external interference (e.g. current/voltage spikes). the regulator supplies the enti re system to ensure high rejection of power supply noise. absolute maximum ratings (25 o c [77 of] free air temperature unless otherwise noted.) storage temperature -40 o c to 100 o c [-40 of to 212 of] lead solder temperature 10 s at 260 o c [500 of] supply voltage 6 v junction temperature 150 o c [302 of] recommended operating conditions operating temperature 0 o c to 70 o c [32 of to 158 of] supply voltage 4.75 v to 5.25 v optical input power -20 dbm to -5 dbm figure 1: spectral sensitivity 300 400 600 700 500 800 1200 900 10001100 (nm) 0 0.1 0.2 0.3 0.4 0.5 a/w n+/p-sub notice ? stresses greater than those listed under ?absolute maximum ratings? may cause permanent damage to the device. ? this is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. ? exposure to absolute maximum rating conditions for extended periods of time may affect reliability. failure to comply with these instructions could result in death or serious injury. table 1: electro-optical characteristics (t c = 25 oc [77 of], v cc = 5 v unless noted) parameter test condition symbol min. typical max . unit data rate ? dc dc ? 16 mbps current consumption ? icc ? ? 45 ma 660 nm max. received power/optical level low 1 mm/pof p rmaxl ? ? -31 dbm max. received power/optical level high 1 mm/pof p rmaxl ? ? -5 dbm max. received power/optical level high 1 mm/pof p rminh -20 ? ? dbm output voltage high i oh = 2 ma@20 pf load v ohigh 2.4 ? ? v output voltage low i ol = 2 ma@20 pf load v olow ? ? 0.4 v rise time 10 % - 90 % t r ? 6 10 ns fall time 90 % - 10 % t f ? 8 10 ns pulse width distortion f = 8 mhz, 50 % duty cycle, p oin = -20 dbm to -5 dbm (average) pwd ? ? 22 ns dynamic range ? ? 15 ? ? db bit error rate ? ber ? ? <10-9 ?
