1.25 Gb/s Integrated 850 nm MSM-TIA AMT128502A Data sheet - Rev. 0 FEATURES · 1.25 Gb/s Differential Output TIA · 5V Operation · Automatic Gain Control · 850nm Photodetector with 100 mm x 100 mm Active Area · Integrated MSM detector & TIA · TO-46 Ultra Flat Window APPLICATIONS · · Gigabit Ethernet (1.250Gb/s) Fibre Channel (1.0625 Gb/s) T46F TO-46 Ultra Flat Window Package Product Description The ANADIGICS AMT128502A is a 5V 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 packaged receiver pass stringent reliability requirements. These products are readily designed into receivers and transceivers for Gigabit Ethernet and Fibre Channel applications.
