Abstract: A single-chip integrated circuit for high-speed optoelectronic transmitting and receiving is provided. The single-chip integrated circuit may include a laser driver, a limiting amplifier, a flash memory and a micro-programmed controller unit (MCU). The laser driver may be configured to accept a high-speed digital electrical signal and drive a laser diode to create an equivalent optical signal. The limiting amplifier may be configured to accept high-speed small signals from an optical detector and amplifiers and limit the high-speed small signals to create a uniform-amplitude digital electrical signal. The flash memory may be configured to store a program code and data related to transmitter and receiver circuits. The MCU may be configured to generate control signals to control the laser driver and the limiting amplifier according to the data stored in the flash memory.
