IRVINE, Calif. -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of analog and mixed signal integrated circuits, has announced two new coplanar waveguide (CPW) photodiode families targeting applications in 1/10 Gigabit Ethernet, Fibre Channel, Infiniband, VCSEL and SONET/SDH OC48 and OC192 systems. The two photodiode families -- designed using advanced gallium arsenide (GaAs) and indium gallium arsenide (InGaAs) fabrication technology -- provide a choice of single die or photodiode arrays, targeting 850 nanometer and 1310/1550 nanometer optical wavelengths for applications using 3.125, 10, or 12.7 Gbps data rates. "Because these photodiodes are designed with easier assembly in mind -- to cut production costs - we see the LX304x(tm) and LX305x(tm) Series as providing attractive choices for manufacturers of broadband systems equipment," said Paul Bibeau, Microsemi Vice President of Corporate Marketing. The new photodiodes feature 75 nanometer square anode and cathode pads that facilitate faster and more reliable self-alignment for either wirebond or flip chip assembly. Their impressive performance results in part from a 50-Ohm characteristic impedance-matched design that minimizes electrical reflections and noise. Microsemi Corp.
