Abstract:
1. A modem comprising: a receiver associated with a receive timing scheme; a transmitter associated with a transmit timing scheme; and only one timing mechanism (i) using only a symbol clock derived from a signal received as input to the receiver wherein the symbol clock represents the receive timing scheme, (ii) electrically coupled to the receiver and the transmitter, (iii) including a single phase accumulator shared between the receiver and transmitter, configured to synchronize the receive and transmit timing schemes, and (iv) including a single coefficient generator shared between the receiver and transmitter, wherein the single coefficient generator is (i) coupled directly to the transmitter and the receiver, (ii) configured to receive re-sampler control signals based on the single phase accumulator, and (iii) provide a set of receive re-sampler coefficients directly from the single coefficient generator to the receiver, and provide a set of transmit re-sampler coefficients directly from the single coefficient generator to the transmitter, based on the received re-sampler control signals.
