Abstract
An apparatus and method are disclosed to aid a transceiver chip, in a wide-band serial data communications system, in receiving data at multiple data rates. A multi-rate filter within the transceiver chip is implemented as at least one adjustable-rate filter stage and a limiting stage. The at least one adjustable-rate filter stage is used to generate a filtered serial data signal from a received serial data signal. The limiter stage generates a full-swing serial data signal from the filtered serial data signal. A bandwidth of the at least one adjustable-rate filter stage is adjustable in order to receive serial data signals at multiple data rates. The bandwidth of the multi-rate filter within the transceiver chip is selectable by the user of the wide-band communication system.
