M02009
Pin Pre-amplifier with AGC for 3.3V Fiber Optic Applications to 622 Mbps
F
EATURES
Low cost IC fabricated in CMOS.
Receiver sensitivity better than -32 dBm @ 622
Mbps.
Minimum 340 MHz bandwidth and multi-pole roll off
allows a wide range of operation up to 622 Mbps.
Typical differential transimpedance at low signal
levels of 40 KΩ.
AGC gives continuous operation to +3 dBm
> 33 dB power-supply noise rejection.
Typical 130 mW power comsumption at 3.3V supply.
Monitor output gives linear indication of received
optical power.
Differential output.
D
ESCRIPTION
The MC2009 is a low-noise, transimpedance amplifier
with AGC, manufactured in low-cost CMOS. Its wide
dynamic range, differential output and high PIN bias make
it well suited for telecommunications, especially OC-12/
STM-4. However, the MC2009 is intended to meet the
needs of both Telecom and Datacom users.
The MC2009 is available in die form. For optimum system
performance die should be mounted in close proximity
with the photodetector.
The MC2009 is designed to be used with the Mindspeed
MC2044C Postamplifier IC. When combined with a
photodiode, the chip set forms a high performance, low
cost 3.3V receiver.
