6: Measured with input signals conforming to SP1 MOST specification of physical layer rev. 1.0.
*7: Average value measured with a plastic fiber (
φ
1 mm, SI-POF, NA=0.5, 1 m) made by Mitsubishi Rayon.
*8: Measured with BiPhase PRBS at 45.2 Mbps (NRZ signal conversion).
NOTE) 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.
