Figure 12 illustration calcspar according to the circuit arrangement of the transceiver module 200 of second embodiment is shown.As shown in figure 12, have according to the transceiver module 200 of present embodiment and provide circuit 26 according to the transceiver module as shown in Figure 9 100 of first embodiment identical configuration and detection/electric power.
Detection/electric power provides circuit 26 to detect the type of the cable (electric wire/optical cable 154) that is coupled with balanced transmission connector 103.That is to say that the type that detection/electric power provides circuit 26 to detect cable is cable or optical cable.But, cannot will have the optical cable and balanced transmission connector 103 couplings of conventional shape.Therefore, use as shown in figure 13 optical cable balanced transmission connector 250 in the present embodiment.
Optical cable balanced transmission connector 250 has the balance transmission plug (the moon) 153 identical with balance transmission cable 150 on an end of balanced transmission connector main body 252, and has the optical cable socket 255 that will insert optical cable 254 on the other end of balanced transmission connector main body 252.The photoelectric conversion section 256 that will have photo-electric conversion element is installed on the optical cable socket 255.Therefore, convert the electrical signal to light, or convert light signal to electric signal.Optical cable socket 255 and photoelectric conversion section 256 generally are installed on the plate in the optical cable balanced transmission connector 250.For this reason, make the part of optical cable socket 255 and the part of photoelectric conversion section 256 be exposed to the outside of shell 251, so that make whole optical cable balanced transmission connector 250 miniaturizations.
Then, provide the circuit arrangement of circuit 26 to be described with reference to Figure 14 to detection/electric power.As shown in figure 14, detection/electric power provides circuit 26 to have testing circuit 26a and electric power provides circuit 26b.
The coupling of one of earth terminal of testing circuit 26a and CX4 interface 15.As an example, in the present embodiment illustration the situation of testing circuit 26a and terminals G7 (Type_SENCE) coupling.When cable and 15 couplings of CX4 interface, that is to say, when balance transmission cable 150 as shown in Figure 5 is coupled with balance transmission plug (sun) 130, the ground GND coupling in terminals G7 and the balance transmission cable 150.If before ground GND coupling, the conductor resistance in the balance transmission plug (sun) 130 and total resistance of the conductor resistance in the balance transmission yarn 150 equal Rc, then the current potential on the A point as shown in figure 14 equals Vcc * (Rc/ (R2+Rc)).Because it is too little that total resistance of conductor resistance is compared with the resistance of resistance R 2, the current potential on the A point is approximately equal to zero.
Current potential on the A point is applied on the non-inverting input (+) of the inverting input (-) of comparator C OMP1 and comparator C OMP2.On the other hand, reference voltage Vcc * ((R4+R5)/(R3+R4+R5)) (this value is called reference voltage 1), be applied on the non-inverting input (+) of comparator C OMP1.Reference voltage Vcc * (R5/ (R3+R4+R5)) (this value is called reference voltage 2), be applied on the inverting input (-) of comparator C OMP2.
In above-mentioned configuration and since the A point on current potential less than reference voltage 1, the output of comparator C OMP1 is " height " level.On the contrary and since the A point on current potential less than reference voltage 2, the output of comparator C OMP2 is " low " level.In the output feed-in and circuit AND1 with comparator C OMP1 and COMP2.Because the output of comparator C OMP1 and COMP2 is respectively " height " level and " low " level, with the output of circuit AND1 be " low " level.Therefore, power switch circuit 262 disconnects, and electric power is not offered terminals G8.
Then, to being described with the situation of balanced transmission connector 250 couplings.Terminals G7 is by resistance R o in the optical cable balanced transmission connector 250 and ground GND coupling.The resistance of supposing resistance R o is deferred to following equation " R5/ ((R3+R4+R5)＜Ro/ (R2+Ro)＜(R4+R5)/(R3+R4+R5) ".In this case, the A current potential of ordering is represented with following equation " Vcc * (Ro/ (R2+Ro)) ".This current potential is lower than reference voltage 1, and the output of comparator C OMP1 is " height " level.In addition, the current potential on the A point is higher than reference voltage 2.And the output of comparator C OMP2 is " height " level.Therefore, the output with circuit AND1 is " height " level.Consequently, power switch circuit 262 is connected, and electric power is offered terminals G8.
Then, to not having member and balance transmission plug (sun) 130 engagements, that is to say that the open situation of terminals G7 is described.When terminals G7 was open, power source voltage Vcc was applied on the A point by resistance R 2, and the current potential on the A point is the voltage voltage vcc no better than.In this case, the current potential on the A point is higher than reference voltage 1, and the output of comparator C OMP1 is " low " level.On the contrary, because the current potential on the A point is higher than reference voltage 2, the output of comparator C OMP2 is " height " level.Therefore, the output with circuit AND1 is " low " level.Consequently, power switch circuit 262 disconnects, and electric power is not offered terminals G8.This is in order to reach the process of security purpose.
Here, in table 1, provided detection/electric power provide TYPE_SCENE on the circuit 26 input voltage, comparator C OMP1 and COMP2 and and the on off state of the output voltage of circuit AND1 and power switch circuit 262 between relation.
Table 1
As shown in table 1, have only input voltage as TYPE_SENCE to be higher than reference voltage 1 (for example, 0.8V) and be lower than reference voltage 2 (for example, in the time of 2.4V), power switch circuit 262 is just connected.
According to present embodiment, transceiver module 100 can detect the type of the cable that is coupled with transceiver module 200 and can operate according to type.
