PIN DESCRIPTIONS Pln l Photodiode Bias: PIns 3, 7, 10, 11, 16, 25 N.C. : This pin is connected to the PIN photodiode cathode. It These pins are not used in the present RCV1201-622 is normally reverse biased with +5 Volts through an design. They should be left as an open circuit. appropriate decoupling network. Current drawn will be directly proportional to input optical signal level. Pin 13 Reserved: This pin is reserved for future product enhancements. It Pins 2, 8, 17, 19 -5 Volt Supply: should be left as an open circuit. These pins are connected to the -5 Volt supply. Each pin should bebypassedwitha series networkof 22Q/100 nF Pin 21 DATA OUTPUT: (See Figure 2). This pin is the inverted data oLrtput. It is at ECL Logic LOWduring aninput opticalpulse. It must beterminated Pins 4, 9, 12, 27 +5 Volt Supply: to a negative supply. These pins are connected to the+5 Volt supply. Each pin should bebypassedwitha series networkof 22CVlOOnF Pin 23 DATA OUTPUT: (See Figure 2). This pin isthe dataoutput. It is at ECL Logic HIGH during an input optical pulse. It must be terminated to a Pins 5, 6, 14, 15, 18, 20, 22, 24, 26, 28 GND: negative supply. These pins are connected to the circuit board ground plane.
