OIA3 Optical Receiver with TTL Output General Description New optical receiver based on a photoASIC device made by a CMOS microelectronic silicon photodiode with integrated electronics for standard TTL digital output. The photoASIC has been developed with high resolution CMOS technology, in order to have higher baudrate (up to 20 Mbps). The optimization of antireflective coating permits to have very good optical sensitivity with low power of the incoming light. The main advantage of this innovative digital optical receiver, in comparison to the standard ones, is the higher speed for industrial LAN and FIELDBUS and the robustness against ESD and EMC. The main technical specifications, like optical sensitivity, voltage and current supply, operating frequency and optical dynamic range, are well improved for this class of optical receivers. The package is a metal TO-18, covered by metal cup with glass window, the outside diameter is standard 5 mm. The CMOS technology and the metal package permit to have high quality device with very high immunity to ESD and EMC.
