2.125 Gb/s Integrated 850nm MSM-TIA Data Sheet - Rev 0 AMT8301 FEATURES · Differential Output TIA · 3.3V Operation · Automatic Gain Control · Integrated 850nm MSM Detector & TIA · TO-46 Ultra Flat-Window or Lens Hermetic Package · High Reliability APPLICATIONS · 2x Fibre Channel (2.125 Gb/s) T46F TO-46 Ultra Flat Window Package T46L TO-46 Lens Package Product Description The ANADIGICS AMT8301 is a 3.3V monolithically integrated Metal-Semiconductor-Metal (MSM) photodetector and transimpedance amplifier (TIA) used to convert an 850nm input optical signal into a differential output voltage, and is manufactured in ANADIGICS’ 6” GaAs wafer fabrication facility. The integrated MSM and TIA receiver maximizes the receiver performance by minimizing the photodetector input parasitics to the TIA and internally biasing the photodetector to achieve high sensitivity, bandwidth and overload performance. As an integrated product the reliability is inherently better than a discrete solution, and both the MSM-TIA integrated circuit and TO46 flat window and TO46 lens packaged receiver pass stringent reliability requirements. These products are readily designed into receivers and transceivers for 2X Fibre Channel applications.
