PRODUCT DESCRIPTION\nThe ANADIGICS ATA7609 is a –5.2 V high-speed transimpedance amplifier (TIA) designed for 10 Gb/s optical receiver applications available in bare die form and manufactured using an InGaP based HBT process. The device is used in conjunction with a photodetector to convert an optical signal into a differential output voltage that can be AC or DC coupled to a post amplifier. The ATA7609 has an internal overload support circuit and can accept optical inputs as high as +3 dBm. With its low noise and high optical overload capability, the device is well suited for 10 Gb/s Ethernet and OC-192 Very Short-Reach (VSR), Short-Reach, Intermediate-Reach and Long-Reach optical receivers, transceivers and transponders. The ATA7609 is identical to the ATA7603 but with the output polarities reversed.FEATURES\n• 1800 Ω Differential Transimpedance\n• 3 mApp Maximum Input Current\n• 14 pA/√Hz Input Noise Current Density\n• Single –5.2 V Power Supply\n• Low Group Delay\n• Outputs DC or AC Coupled\n• Same Functionality as ATA7603 with the Output Polarities ReversedAPPLICATIONS\n• SONET/SDH OC-192 /STM-64 VSR, Short-Reach, Intermediate-Reach, and Long-Reach Receivers\n• 10 Gb/s Ethernet\n• Fiber optic receivers, transceivers, and transponders
