Microcosm - invalid (Microcosm Communications Ltd. ) : MC2008

Pre-amplifier with AGC for long reach fiber optics based 622 Mbps ATM

The MC2008 is a transimpedance amplifier with AGC manufactured in a 0.6µ pure-CMOS process. The AGC allows >36dB dynamic range, giving a CMOS solution to longer-reach 622Mbps ATM/SONET systems for the first time. For optimum system performance the MC2008 die should be mounted with a silicon or InGaAs PIN photodetector inside a lensed TO can. A 470pF decoupling capacitor mounted inside the TO can, though optional, will give maximum power supply noise rejection (40dB). The MC2008 reverse biases the PIN by approx. 2.3volts to optimise the PINs performance. Its very low noise and differential output provide for enhanced performance over existing devices. Features are

• Low-cost IC, available as die or in SO8 package. Fabricated in standard 0.6µ CMOS process
• Min. 350MHz bandwidth/622Mbps datarate, >39dB dynamic range
• Min. -33dBm sensitivity, +3dBm saturation at 622Mbps when used with 0.9A/W InGaAs PINs. (BER 10-9)
• 200 ohms to 60k ohms transimpedance range
• Differential output
• Operates with standard +5Volt or ECL supplies
