Transmitter/receiver photo IC for optical link  
L8628, S8627-01A  
For MOST automotive network, 50 Mbps band POF communications  
L8628 and S8627-01A are transmitter and receiver photo ICs developed for MOST (Media Oriented System Transport) networks used in 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 "sleeping 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.

*1: Measured with input signals conforming to SP3 MOST specification of physical layer rev. 1.0.  
*2: Measured with RL=50 kΩ, CL=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 µF) connected between Vcc and GND at a position within 3 mm from the lead, and  
a 10 µF 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.
