DPRV2021A
Product Description
The photoreceiver module DPRV2021A is a differential front-end with a high bandwidth of 40 GHz and differential gain of typically 300 V/W. The receiver is therefore well suited for OC-768/STM-256 system operation of up to 43 Gbit/s. The photoreceiver contains a waveguide-integrated pin-photodiode (PD) and a transimpedance amplifier (TIA) with limiting output buffer. An automatic control of the output voltage by an integrated feedback loop optimizes the performance in the frequency and/or time domain with respect to different optical input power resulting in a wide dynamic range of an optical input power between -11 dBm and +5 dBm.. Due to the limiting output buffer the output voltage swing is limited to approx. 500 mV. A DC-coupled version without blocking capacitors is available upon request (DPRV2021).
