MC2010

1.25 Gbps AGC Pre-Amplifier


Overview

Description

The MC2010 is a low-noise transimpedance amplifier with AGC and is available in die form. The MC2010 has low noise and wide dynamic range, making it well-suited for telecommunications (especially OC-24). The MC20S10 has lower gain and is designed for use with low-cost, higher- capacitance photodiodes (including Si diodes) in datacom applications. The MC2010 is available in die form. It is recommended that both the MC20L10 and MC20S10 be used in conjunction with the MC2046 post-amplifier. When combined with a photodiode, the MC2010/MC2046 chipset forms a high-performance, low-cost 3.3 V receiver.

Features

  • Low-cost IC, fabricated in advanced sub-micron pure CMOS process
  • Typical differential transimpedance at low signal levels of 16 kohms (MC20L10) and 8 kohms (MC20S10)
  • AGC gives continuous operation to +3 dBm
  • Available as die
  • 35 dB power supply noise rejection
  • Minimum 830 MHz bandwidth and multi-pole roll-off allows a wide range of operation up to 1.25 Gbps
  • Power dissipation of 100 mW at 3.3 V supply typical
  • Monitor O/P gives linear indication of received optical power
  • Receiver sensitivity better than -27 dBm at 1.25 Gbps (MC20L10)
