*2: Electrical interface conforms to LVDS standards except common mode input voltage.
*3: Connect a bypass capacitor (0.1 μF) between Vcc and GND at a position within 3 mm from the leads. Also connect a 10 μF capacitor
near the photo IC.
L11354-01: 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.
