IC
Transmitter/receiver photo IC for optical link
For MOST automotive network, 50 Mbps band POF communications
L8628-01B, S8627-01B
L8628-01B and S8627-01B 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 L8628-01B 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 S8627-01B 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 conform ing to SP3 MOST specification of physical layer rev. 1.0.
*2: Measured with RL=50 k
, 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 Ham am atsu standard transm itter.
*4: Average optical power is m easured with a POF (NA=0.5).
*5: Measured with BiPhase PRBS at 45.2 Mbps (NRZ signal conversion).
Note) If m odulated light at 4 Mbps or less (including DC light and no light input) is input to S8627-01B, 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 m m.
