Abstract:
A clock recovery mechanism for an ATM receiver for recovering a service clock transmitted over an ATM network, said mechanism comprising:an input for receiving an SRTS from said ATM network; a local SRTS generator for locally generating an SRTS; a comparator for comparing said received SRTS and said locally generated SRTS; a controller configured to generate two or more control signals in response to (i) an output of said comparator and (ii) a clock signal; and a clock generator configured to generate said recovered service clock in response to said two or more control signals and said clock signal, wherein said clock generator is configured to generate a plurality of pulses in response to said two or more control signals and said clock signal, where a first one of said two or more control signals is configured to advance said plurality of pulses and another of said two or more control signals is configured to deli said plurality of pulses.
