S8046 is optical communication devices designed for pof (plastic optical fiber) data links. S8046 is a high sensitivity, high-speed photo ic that receives signals at 50 mbps and covers a wide dynamic range of 21.5 db. the output is ttl compatible. S8046 also features a sleeping mode in which operation automatically switches to low power dissipation mode when no light is input and switches back to normal operation mode when light is input from the optical fiber. the internal ic checks which mode is current ly selected and this check signal is available from the mode output terminal. current consumption in sleeping mode is approximatel y 1/400th that of normal operation mode. photo ic photo ic for optical link receiver with sleeping mode suitable for 50 mbps optical link S8046 features l sleeping mode (low power dissipation) l 4 to 50 mbps l monolithic photo ic l high reliability l ttl output l wide dynamic range l designed to be used with l8045 applications l high-speed data transmission even under poor environmental conditions with high noise absolute maximum ratings (ta=25 c) parameter s y mbol value unit supply voltage vcc -0.5 to +7.0 v output voltage vo -0.5 to vcc+0.5 v output current io 10 ma power dissipation p 250 * 1 mw operating temperature topr -40 to +85 c storage temperature ts tg -40 to +85 c soldering - 230 c, 5 s, at least 1.8 mm awa y from packa g e surface - *1: derate power dissipation at a rate of -1.75 mw /c above ta=25 c electrical and optical characteristics (ta=25 c, vcc=4.5 to 5.5 v) parameter s y mbol condition min. typ max. unit data rate fd bi-phase signal 4 - 50 mbps current consumption ( in operation mode ) icco * 2, 3 - - 40 ma current consumption ( in sleepin g mode ) iccs pin= - - - 100 a minimum overload pimax * 2, 3, 5, 6 -8 - - dbm minimum receiver input power pimin * 2, 3, 5, 6 - - -28.0 dbm h level output voltage voh ioh= -150 a * 2, 3 2.7 - - v l level output voltage vol iol=1.6 ma * 2, 3 --0.4v rise time tr - - 5 ns output volta g e fall tim e tf 20 to 80 % * 2, 3 --5ns pulse width distortion ? t * 2, 3 -4 - +8 ns jitter ? tj * 2, 3 --5ns operation mode to sleeping mode switching input power psl * 2, 3, 5 - - -33 dbm sleeping mode to operation mode switching input power pop * 2, 3, 5 ---30dbm sleeping mode to operation mode switching time tso * 2 - - 200 s operation mode to sleeping mode switching time tos * 2 - - 500 s h level voltage vmh * 7 3.0 - - v mode output l level voltage vml * 7 --0.5v *2: input is a pseudo-random bi-phase signal at 50 mbps. *3: c l =5 pf (including parasitic capacitance of probes, connectors and pc board) *4: optical input signal is generated by our standard signal generator. *5: average value (at 50 % duty ratio) *6: pe=10 -9 *7: ?h? in sleeping mode, ?l? in operation mode note) a bypass capacitor (0.1 f) and another capacitor (4.7 f) are connected between vcc and gnd at a position within 3 mm from the lead. the center of the optical fiber is aligned with the center of the lens on the package. the distance between the fiber end and the lens is 0.1 mm. output becomes undefined at a baud rate less than 4 mbps. 1
