  • Method for deskewing FPGA transmitter channels directly driving an optical QPSK modulator
    Patent number: 11558120
    Abstract: A Field Programmable Gate Array (“FPGA”) transmitter reliability directly drives an optical modulator. Each time the FPGA is powered up, the transmitters are aligned using optical feedback for coarse and fine alignments. The fine alignment may be executed using a built-in transmitter phase interpolator Parts-Per-Million (“PPM”) controller.
