Abstract
Transceiver circuitry (10, 200) for use in a GBIC module uses readily available off the shelf components to satisfy the specifications of the GBIC standard. In both passive and active modules, a voltage divider (98) and parallel transistors (94, 96, 100) are utilized to insure that the differential voltage of the received differential signal is at an acceptable level. In active modules, a diode cross over quad (84) is utilized to extend the input range of a low input differential receiver (78) and a coaxial cable driver (60) designed to drive 50 ohms is utilized to drive 150 ohms.
