F0100404B
3.3V/5V 1.25 Gb/s Receiver
Transimpedance Amplifier
♦ Applications
• G bit Ethernet (1.25 Gb/s)
• Preamplifier of an optical receiver circuit for fiber channel (1.0625 Gb/s)
♦ Functional Description
The F0100404B is a stable GaAs integrated transimpedance amplifier capable of 16 dB
gain at a typical 1900 MHz 3 dB-cutoff-frequency, making it ideally suited for an optical
receiver circuit for a Gbit Ethernet (1.25 Gb/s), instrumentation, and measurement applica-
tions. The integrated feedback loop design provides broad bandwidth and stable operation.
The F0100404B typically specifies a high transimpedance of 600 Ω (RL=50 Ω) with a wide
dynamic range of over 20 dB. Furthermore, it can operate with a supply voltage of single
+3.3V or +5.0 V. It features a typical dissipation current of 43 mA.
Only chip-shipment is available for all product lineups of GaAs transimpedance amplifi-
ers, because the packaged preamplifier can not operate with the maximum performance
owing to parasitic capacitance of the package.
