MC2006
CMOS Pre-amplifier with AGC for Long-reach
155 Mbps Fiber-optics Based Transmitter
The MC2006 is a low-noise, transimpedance amplifier with AGC, manufactured in sub-micron CMOS. Its wide
dynamic range, differential output and high PIN bias make it well suited for telecommunications, especially OC-3/
STM-1. However, the MC2006 is intended to meet the needs of both Telecom and Datacom users.
The MC2006 is available only in die form. For optimum system performance, die should be mounted in close
proximity with the photodetector.
The MC2006 is designed to be used with the MC2045 postamplifier IC. When combined with a photodiode, the
chip set forms a high performance, low cost 5 V receiver.
Features
• Low-cost IC, fabricated in sub-micron CMOS
• Receiver sensitivity typically -40 dBm at 155 Mbps, when
integrated into a module with suitable photodiode and post-
amplifier
• 115 MHz bandwidth allows wide range of operation; suitable for
100, 125 and 155 Mbps
• Typical differential gain of 200 kΩ at low signal levels
• AGC gives continuous operation to >0 dBm
• 165 mW power consumption at +5 V supply
• > 35 dB Power-supply noise rejection
• Available as die
Applications
• SDH / SONET / ATM
• Fast Ethernet
