F0100406B
3.3V 1.25Gbit/s NRZ Receiver
Transimpedance Amplifier
Applications
- Preamplifier of an optical receiver circuit for GbE (1.25Gbit/s)
Functional Description
The F0100406B is stable GaAs integrated transimpedance amplifier. Typical Applications are for 1.25Gbit/s
optical receiver circuit, for example, GbE, instrumentation, and measurement applications. The integrated
feedback loop design provides broad bandwidth and stable operation. The F0100406B typically specifies a high
transimpedance of 5.0Ω (RL=50Ω) at a typical 900MHz O/E bandwidth (-3dB-cutoff frequency) with a dynamic
range of over 30dB. It also provides a large optical input overload of more than +2dBm. Furthermore, it can
operate with a low supply voltage of single +3.3V. It features a typical dissipation current of 45mA.
Only chip-shipment is available for all product lineups of GaAs transimpedance amplifiers, because the
packaged preamplifier cannot operate with the maximum performance owing to parasitic element of the package.
