PIN ASSIGNMENT

 

Pin Number Symbol Name Description
1,17,20 VeeT Transmitter signal ground These pins should be connected to signal groundon the host board.
2 TX fault Transmitter fault out (OC) Logic “1” output = Transmitter fault
Logic “0” output = Normal operation
This pin is open collector compatible, and should be pulled up to host
Vcc with a 10kΩ resistor.
3 TX disable Transmitter disable in (LVTTL) Logic “1” input (or no connection) = Laser off
Logic “0” Input = Laser on
This pin is internally pulled up to VccT with a 10 kΩ resistor
4 SDA Module definition identifiers Serial ID with SFF 8472 diagnostics module definition pins should be pulled up to Host Vcc with 10 kΩ resistors.
5 SCL
6 MOD-ABS
7 RS0 Receiver rate select (LVTTL)
Transmitter rate select (LVTTL)		 NA
9 RS1 NA
8 LOS Loss of signal out (OC) This pin is open collector compatible, and should be pulled up to host
Vcc with a 10kΩ resist
10,11,14 VeeR Receiver signal ground These pins should be connected to signal groundon the host board.
12 RD- Receiver negative DATA out (CML) Light on = logic “0” output receiver DATA output is internally AC coupled and series terminated with a 50Ω resistor.
13 RD+ Receiver positive DATA out(CML) Light on = Logic “1” output receiver DATA output is internal
ly AC coupled and series terminated with a 50 Ω resistor.
15 VccR Receiver power supply This pin should be connected to a filtered +3.3V power supply on the host board. See figure 3.recommended power supply filter
16 VccT Transmitter power supply This pin should be connected to a filtered +3.3V power supply on the  host board. See figure 3.recommended power supply filter
18 TD+
Transmitter positive DATA in(CML)
 Logic “1” input = light on transmitter DATA inputs are internally AC coupled and terminated with a differential 100Ω resistor.
19 TD- Transmitter negative DATA in(CML) Logic “0” input = light on transmitter DATA inputs are internally AC coupled and terminated with a differential 100Ω resistor.
