Abstract

Abstract Microprocessor and transceiver circuitry are incorporated into a single c for enhanced, high speed operation of an electronic circuit board by use of optical fiber connections between two or more of such single chips and external peripherals. The transceiver circuitry includes transmitter and receiver sections through which the optical signals are respectively generated and received by a light emitting diode and a photo-diode.
