Abstract:
A network interface module for a time-division network for transferring data among clients of the network, the network having a system clock signal with a clock rate and period that define bus cycles of the network, each of the bus cycles having a number of time slots for transmitting data over the network, the network interface module comprising:a first clock circuit that generates a first clock signal having a clock rate that is greater than the number of time slots in a bus cycle multiplied by the clock rate of the system clock signal, and having a period that defines a duration of each time slot, the first clock signal being asynchronous with the system clock signal;a second clock circuit, coupled to the first clock circuit to receive the first clock signal, and responsive to the system clock signal to generate a start signal, synchronous with the first clock signal, indicating a start of a bus cycle.
