Quad 26 to 28 GBaud Linear Trainsimpedance Amplifier 53Gbps to 56Gbps

 The MATA-38019 Quad Linear TIA supports 26 - 28GBaud optical data links. The MATA-38019 consumes very low power, typically 190mW per channel at 2.9V, allowing to be used in high density optical interconnect solutions. Features include RSSI for photoalignment, power monitoring, I2C control of Bandwidth, output amplitude and peaking control, LOS (Loss of Signal), Gain and other parameters. The part is available to support wirebond assemblies.
