Methods and apparatus are provided for interconnecting first and second information buses each having a plurality of data lines. A pair of unidirectional information paths each consisting of twisted-pair cables are provided, along with a 25 MHz strobe. Information is transmitted using pseudo-ECL signal levels. A pair of clock differential receiver circuits is provided such that data is transferred over the interconnect bus using both the rising and falling edges of the transmitted clock signal and transferred from one bus to another at a rate of 50 MHz.
