Abstract
A synchronous method for clock recovery for use with constant bit rate (CBR) services over an ATM network is disclosed. A square wave related to the source frequency is compared to a square wave related to the network frequency using an exclusive OR to obtain a duty cycle transported to the receiver. The duty cycle includes information which is sufficient to recover the source clock when the network frequency duty cycle is known.
