Transmitter/Receiver photo IC for optical link
L10663-01, S10664-01
3.3 V operation, for MOST automotive network
L10663-01 and S10664-01 are transmitter and receiver photo ICs developed for MOST (Media Oriented System Transport) networks used in
vehicles to communicate multimedia information. Lower operating voltages in recently manufactured electronic devices have spurred demand for
low-voltage and low-current transmitter/receiver photo ICs. To meet this need, HAMAMATSU has been developing low voltage (3.135 V to 3.465 V)
photo ICs that still maintain a wide operating temperature range (-40 ˚C to +105 ˚C) the same as the conventional types (L10063-01/S10064-01).
The transmitter photo IC L10663 consists of a Red-LED and driver IC 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 S10664 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 or output digital signals
through a TTL interface.

*1: 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 center of the optical fiber is aligned with the center of the package lens. The distance between the fiber end and the lens
top is 0.1 mm.
An external resistor (Rcont) is connected between Cont and -Vcc.
