GPON ONT HG8310M optical network terminal (ONT) is a indoor optical network terminal in FTTx solution. By using GPON technology, ultra-broadband access is provided for home and SOHO users. The HG8310M provides one 10/100/1000M Base-T Ethernet port for connecting to a home gateway. The home gateway then can be connected to a PC, Mobile Terminal, STB, or Video phone to provide high-speed data, video services.
AC Output Voltage Feedback
EG8010 works under two modulation modes: unipolar modulation and bipolar modulation. Under unipolar modulation, only one bridge (EG8010 pins SPWMOUT3 & SPWMOUT4) is used for SPWM modulate output, and another bridge (EG8010 pins SPWMOUT1,SPWMOUT2) is used for fundamental wave output. A filter inductor needs to connect to SPWM output port, and a voltage feedback circuit needs to connect to SPWM inductor's output port(as shown in Fig 8. 1a). Under bipolar modulation, both bridges (EG8010 pins SPWM3, SPWM4, SPWM1, SPWM2) are used for SPWM output. Using both inductors will result in better flirting, a voltage feedback circuit need difference and feedback handling by voltage divider of both channels (as shown in Fig 8.c).
Under unipolar modulation, EG8010's voltage feedback process is through measuring the AC voltage output of inverter by pin(13)VFB. Pin (16)FRQADJ/VFB2 only functions as FRQADJ, while VFB2 feedback has no effect. For such voltage sampling and feedback circuit shown in Fig 8. 1a, it calculates the error between measured peak voltage and the sinusoid voltage reference (3V), and adjusts the output voltage accordingly. When output voltage increases, the pin voltage increases. The circuit does the error calculation and adjust range divider factor, therefore decreases the voltage to achieve voltage stabilization. Conversely, as the voltage on this pin decreases, the chip will increase output voltage.
