The DSC-R603 is a high-gain PIN + Transimpedance + Limiting amplifier ideally suited for digital applications up to 13 Gb/s. The R603 offers extremely high differential conversion gain of 9,000 V/W, high sensitivity of -20dBm, optical overload of +4dBm, and very low power dissipation of 170mW. The R603 is available in three package styles: single-ended K-connector, differential GPPO, and a miniature surface mount package with CPW (coplanar waveguide) RF outputs. The R603 utilizes Discovery's high-reliability InGaAs photodiode technology.

The DSC-R603 Lab Buddy is also available with an optional clock and data recovery (CDR) unit, which provides a 3R solution with a jitter tolerance of 0.6 UIp-p and conveniently interfaces with bit error rate (BER) test stations.
