SIGNAL INPUT
KLEDC0039EA
*3: Input is a pseudo-random bi-phase signal at 125 Mbps (NRZ signal conversion). *4: Average value (duty ratio 50 %) measured by using a plastic fiber of φ1 mm. SI-POF and NA=0.5 (GH4001 made by Mitsubishi Rayon). Note) · A bypass capacitor (0.1 µF) and another capacitor (4.7 µF) are connected between Vcc and GND at a position within 3 mm from the lead. · The center of the optical fiber is aligned with the center of the lens on the package. The distance between the fiber end and the lens is 0.1 mm.
