Linear 53 Gbaud PAM4 Transimpedance Amplifier (TIA)

The MATA-05819B Linear TIA is intended for 50G, 100G, 200G and 400G receivers using multilevel modulation such as PAM4. The TIA provides linear, low noise amplification from 0.1 to 3mA, and has a nominal BW of 30GHz. The trans-impedance is controlled from 150 to 4k via an external pad and the gain is automatically adjusted to provide a constant output voltage swing. Features include: RSSI for photo-alignment and power monitoring, I2C control of output amplitude and other parameters, output EQ, and Loss of Signal (LOS).
