Photo IC for optical link
S7727
Receiver for 156 Mbps POF communications
www.hamamatsu.com 1
S7726 is designed for high-speed POF (Plastic Optical Fiber) communications. Both devices are molded into miniature plastic
packages with lenses, allowing easy and effi cient coupling to a POF. S7727 uses a monolithic photo IC that ensures high re-
sistance to external noise and high reliability, and provides P-ECL voltage conversion output.
Photo IC receiver for POF data link Plastic optical fiber communications (FA, office ma-
chine, home automation, LAN)
Monolithic structure immune from external noise
Data transmission in locations subject to high
electromagnetic noise
Data rates from 4 Mbps to 156 Mbps
P-ECL voltage conversion output
(Note: Unlike normal P-ECL output, S7727 output
cannot be terminated with 50 Ω.)

*3: A 3 pF capacitor is connected to GND as a capacitive load (including parasitic capacitance such as probes, connectors and
evaluation PCB patterns)
*4: An optical input waveform is generated with a Hamamatsu standard transmitter.
*5: A detectable signal level is an average value, measured using a plastic fi ber (GH4001 made by Mitsubishi Rayon).
*6: A 3 kΩ resistor is externally connected between Q and GND and also between QB and GND.
Note)
O A bypass capacitor (0.1 μF) connected at a position within 2 mm from the lead, and a 4.7 μF capacitor is also connected to the power
supply line nearby.
O 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.
O 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.
