s7726 is designed for high-speed pof (plastic optical fiber) communications. both devices are molded into miniature plastic pac kages with lenses, allowing easy and efficient coupling to a pof. S7727 uses a monolithic photo ic that ensures high resistance to externa l noise and high reliability, and provides p-ecl voltage conversion output. photo ic photo ic for optical link receiver for 156 mbps pof communications S7727 features l photo ic receiver for pof data link l monolithic structure immune from external noise l data rates from 4 mbps to 156 mbps l p-ecl voltage conversion output (note: unlike normal p-ecl output, S7727 output cannot be terminated with 50 w .) l designed to be used with l9534 or l7726 applications l plastic optical fiber communications (fa, office machine, home automation, lan) l data transmission in locations subject to high electromagnetic noise 1 absolute maximum ratings (ta=25 c) parameter symbol value unit supply voltage vcc -0.5 to +7.0 v output voltage vo -0.5 to vcc + 0.5 v output current io 8 ma power dissipation pmax 250 * 1 mw operating temperature topr -20 to +70 c storage temperature ts t g -40 to +85 c soldering - 230 c, 5 s, at least 1.5 mm away from package surface - *1: derate power dissipation at a rate of 1.7 mw/c above ta=25 c electrical and optical characteristics (ta=25 c, vcc=5.0 v) parameter symbol condition min. typ. max. unit data rate fd bi-phase signal nrz conversion 4 - 156 mbps current consumption icc * 2, * 3, * 6 - - 40 ma high level output voltage voh ioh= -1 ma * 2, * 3, * 6 3.9 - 4.3 v low level output voltage vol iol= -0.5 a * 2, * 3, * 6 2.9 - 3.4 v minimum overload pimax * 2, * 3, * 4, * 5, * 6 -2 - - dbm minimum receiver input power pimin * 2, * 3, * 4, * 5, * 6 - - -22 dbm rise time tr - - 3 ns fall time tf 10 to 90 % * 2, * 3, * 6 - - 3 ns pulse width distortion ? t* 2, * 3, * 4, * 6 -3 - 3 ns jitter ? tj * 2, * 3, * 4, * 6 - - 3 ns *2: measured with 156 mbps input signal (bi-phase signal) *3: a 3 pf capacitor is connected to gnd as a capacitive load (including parasitic capacitance such as probes, connectors and evaluation pcb patterns) *4: an optical input waveform is generated with a hamamatsu standard transmitter. *5: a detectable signal level is an average value, measured using a plastic fiber (gh4001 made by mitsubishi rayon). *6: a 3 k ? resistor is externally connected between q and gnd and also between qb and gnd. note) a bypass capacitor (0.1 f) connected at a position within 2 mm from the lead, and a 4.7 f capacitor is also connected to the power supply line nearby. the optical axis of the package lens is exactly aligned with the center axis of the optical plug, and the gap between the lens surface and the optical reference plane of the plug is 0.1 mm. if modulated light at 4 mbps or less (including dc light and no light input) is input to S7727, the high and low levels cannot be discerned.
