| features applications led/photo ic transmitter/receiver photo ic for optical link for most automotive network, 50 mbps band pof communications L8628, s8627-01a L8628 and s8627-01a are transmitter and receiver photo ics developed for most (media oriented system transport) networks used i n vehicles to communicate multimedia information. the transmitter photo ic L8628 consists of a red led, driver ic and current regulator chip incorporated into a clear plastic package and can be set to an operating mode that reduces the optical output level by half. the receiver photo ic s8627-01a is a monolithic photo ic fabricated by the pin-bip process and features a wide dynamic range. it also has a low power consumption "s leeping mode" and an optical wakeup mode triggered by input of light. both the transmitter and receiver photo ic input and output digital signals through a ttl interface. l dc to 50 mbps data communications l ttl input l optical output 50 % cut mode l only for vehicle networks (most) L8628 s8627-01a l 4 m to 50 mbps data communications l monolithic structure immune from external noise l ttl output l wide dynamic range l sleeping mode with optical wakeup 1 absolute maximum ratings (ta= 25 c ) parameter symbol L8628, s8627-01a unit supply voltage vcc -0.5 to +7.0 v operating temperature to p r -40 to +95 c storage temperaturetstg-40 to +110 c soldering ts o l 260 c, 5 s, 3 times, at least 2.5 mm away from lead root c electrical and optical characteristics (ta= -40 to +85 c, vcc=4.75 to 5.25 v) parameter symbol condition min. typ. max. unit current consumption (operation mode) icco * 1, * 2 --30 ma current consumption (sleeping mode) iccs dark state - - 30 a receiver level popt3 bi-phase signal -24 - -3.5 dbm high level output voltage voh ioh= -150 m 2.5 - - v low level output voltage vol iol=1.6 ma - - 0.4 v rise time tr - - 9 vout fall time tf 10 to 90 % * 1, * 2 - - 7 ns pulse width variation tpwv * 1, * 2, * 3, * 5 18 -29.8 ns pulse width distortion (average value) tapwd * 1, * 2, * 3, * 5 -1.8 - +6.6 ns operation to sleeping mode transition receivable level psl sleeping mode to operation transition receivable level pop * 1, * 2, * 4 -39 - -25.5 dbm high level voltage vmh ioh= -20 a 4.0 - - v mode out low level voltage vml iol=0.88 ma --0.5 v *1: measured with input signals conforming to sp3 most specification of physical layer rev. 1.0. *2: measured with r l =50 k ? , c l =15 pf (including parasitic capacitance such as probe, connector and evaluation circuit board pattern), and threshold voltage=1.5 v. *3: an optical input waveform is generated with a hamamatsu standard transmitter. *4: average optical power is measured with a pof (na=0.5). *5: measured with biphase prbs at 45.2 mbps (nrz signal conversion). note) ? if modulated light at 4 mbps or less (including dc light and no light input) is input to s8627, the high and low levels cannot be discerned. ? a bypass capacitor (0.1 f) connected between vcc and gnd at a position within 3 mm from the lead, and a 10 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. s8627-01a specifications of these products are subject to change without prior notice to keep up with changes in the most standard.
