Product Overview

The MAX3665EUA+ is a 622Mbps, ultra low power, 3.3V transimpedance preamplifier for SDH/SONET in 8 pin µMAX package. This low power transimpedance preamplifier for 622Mbps SDH/SONET applications consumes only 70mW at VCC = 3.3V. It converts a small photodiode current to a measurable differential voltage. A DC cancellation circuit provides a true differential output swing over a wide range of input current levels thus reducing pulse width distortion. The differential outputs are back terminated with 50 ohm per side. The overall transimpedance gain is nominally 8Kohm. For input signal levels beyond approximately 50µAp-p, amplifier will limit output swing to 250mV. The IC's low 55nA input noise provides a typical sensitivity of -33.2dBm in 1300nm, 622Mbps receivers. It is designed to be used in conjunction with MAX3676 clock recovery and data retiming IC with limiting amplifier. Together they form a complete 3.3V or 5V 622Mbps SDH/SONET receiver.
  • Single supply operation of +3.3V or +5V
  • Operating temperature range from -40°C to 85°C
  • 70mW power consumption at VCC = 3.3V
  • Gain of 8Kohm
  • Peak input current of 450µA
  • Deterministic jitter of 260ps (max)
  • Differential output drives 100 ohm load
  • Bandwidth of 470MHz
  • Maximum output voltage of 260mVP-P (typ) at IIN = 450µAP-P
