Claim 0:
1. A 10G rate OLT terminal transceiver integrated chip based on XGSPON and DFB laser, comprising:
a burst mode receiver RX, a continuous mode transmitter TX and a digital control unit DIGIITAL,
wherein an optical signal from each ONU client is processed through a burst transimpedance amplifier TIA into an electrical signal, then the burst-mode receiver RX amplifies the electrical signal, processes amplitude detection of the electrical signal, determines if an amplitude of the electrical signal meets a threshold requirement, and outputs a detection result of the electrical signal to a host, and comprises a fast recovery module to discharge charges in an AC coupling capacitor to achieve multi-packet transmission without mutual interference, thereby meeting the timing sequence requirement of the XGSPON protocol;
the continuous mode transmitter TX receives the electrical signal attenuated by a PCB board, and in response to a degree of attenuation, selects a bypass path BYPASS for transmission or outputs the electrical signal after a signal quality of the electrical signal is processed and improved by a clock data recovery path CDR to drive the DFB laser; and
the digital control unit DIGIITAL communicates with the host, and provides control signals for the burst mode receiver RX and the continuous mode transmitter TX.
