The MxL9168 is an eight-channel linear 56GBd PAM4 transimpedance amplifier (TIA) array with I2C control and monitor ports. Each amplifier channel includes an adjustable small signal transimpedance gain range of over 30dB. The TIA typically consumes 1.6W for eight channels from a single 3.3V power supply. In addition to ultra-low noise, the total harmonic distortion (THD) is less than 3%. Each TIA channel provides a pin photodiode bias voltage and an RSSI output to monitor the average photodiode current.
