*4: Measured with 156 Mbps input signal (Bi-phase signal)
*5: A 3 pF capacitor is connected to GND as a capacitive load (including parasitic capacitance such as probes, connectors and
evaluation PCB patterns)
*6: An optical input waveform is generated with a Hamamatsu standard transmitter.
*7: A detectable signal level is an average value, measured using a plastic fiber (MH4001 made by Mitsubishi Rayon).
*8: A 3 kW resistor is externally connected between Q and GND and also between QB and GND.
Note)
G A bypass capacitor (0.1 µF) connected at a position within
2 mm from the lead, and a 4.7 µF capacitor is also con-
nected to the power supply line nearby.
G 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.
G If modulated light at 4 Mbps or less (including DC light and
no light input) is input to S7727, the high and low levels
cannot be discerned.
