FEATURES · 1.25 Gb/s Differential Output TIA · Automatic Gain Control · Single +5V Supply · 1100 MHz Bandwidth · -28 dBm typical sensitivity · On-Chip PIN Photodiode Bias Voltage APPLICATIONS · Gigabit Ethernet (1.250 Gb/s) · Fibre Channel (1.0625 Gb/s) ATA121302 1.25Gb/s Transimpedance Amplifier ADVANCED PRODUCT INFORMATION - Rev 0.1 D1C PRODUCT DESCRIPTION The ANADIGICS ATA121302 is a +5V low noise transimpedance amplifier designed to be used in Gigabit Ethernet and Fiber Channel fiber optic links. The device is used in conjunction with a photodetector (PIN diode or avalanche photodiode) to convert an optical signal into a differential output VDD voltage. The ATA121302 offers a bandwidth of 1100MHz, a dynamic range in excess of 28dB and an on-chip bias voltage for PIN photodetectors. It is manufactured in a GaAs MESFET process and is available in bare die form. 4K IIN VOUT VOUT AGC US Patent: 5047728, 5602510 Charge 6.5 GHz VN Pump Osc US Patent Pending GND The ...
