Ewing, NJ - November, 2016
Discovery Semiconductors introduces a linear PIN + transimpedance amplifier with user-adjustable gain and is primarily designed for 25 to 28 Gbaud / 50 to 56 Gbps Pulse Amplitude Modulation (PAM-4) and 25 to 28 Gbps NRZ-ASK (PAM-2) modulation formats for 1310 nm and 1550 nm single-mode systems. This new product, the DSC-R418, is currently available only in Discovery’s self-contained Lab Buddy instrument.

Mr. Aaron Berry, Sr. Global Sales Engineer commented, “Initially, our plans are to release this product in a Lab Buddy, thus, allowing our customers a quick and easy solution to benchmark their link performance. At a later date, with advise from our customers, we will release this product in a suitable butterfly or surface mount package for volume production.”
Added Mr. Abhay Joshi, President and CEO, “With Content Distribution Networking becoming ubiquitous the need for super datacenters is now and real. Both PAM-2 and PAM-4 will be widely used in these datacenters. The new DSC-R418 receiver will serve the need of the optical community for years to come.”
