Quad Linear 26/53 Gbaud PAM4 Transimpedance Amplifier (TIA)

 The MATA-03821/22 Quad Linear TIA family support high bandwidth optical data links. The MATA-03821/22 consume very low power, typically 192mW per channel at 2.9V, allowing to be used in high density optical interconnect solutions. Features include RSSI for photo-alignment and power monitoring, and I2C control of Bandwidth, Output Amplitude, Peaking, Loss of Signal (LOS), Gain and other parameters. Multiple part numbers are available to support both wirebonded and flip chip assemblies.
