  • Method and apparatus for synthesizing clock signals for use with an asynchronous transfer mode system having selectable data transmission rates
    Patent number: 5600650
    Abstract: An asynchronous transfer mode (ATM) segmentation and reassembly (SAR) chip is provided for interfacing a host computer with an ATM system having a physical layer (PHY) chip incorporating, for example, a Unified Test and Operations Physical Interface for ATM (UTOPIA) protocol. The PHY chip is capable of operating at both 155 Mbps and 622 Mbps data transmission rates. The UTOPIA protocol requires a clock which is provided by the SAR chip. In an exemplary embodiment described herein, the SAR chip is configured to accommodate both data transmission rates and to synthesize appropriate clock signals for driving the PHY chip which facilitate the clocking out of data and the sampling of data.
