摘要：
High-speed serial data signal transmitter and/or receiver circuitry is able to dynamically switch between handling data at two (or more) different data rates. Such a switch can be made very rapidly and with no requirement for reprogramming or reconfiguring the circuitry. Circuitry for glitchlessly switching between clock signals having different frequencies is also provided and may be used in the above-mentioned transmitter and/or receiver circuitry.
