Abstract
A network transmitter and an associated transmitting method are disclosed. The network transmitter includes a signal converter and a signal driver. The former can convert an input signal into a current signal, and the latter can output a differential transmission signal according to the current signal. The signal driver includes a feedback network which can switch between a first configuration and a second configuration.
Claims26
A transmitter of a network device for outputting a transmission signal at a transmission rate, which is either a first transmission rate or a second transmission rate, the transmitter comprising:
- a signal converter configured to convert an input signal into a converted signal;
- and
- a signal driver, coupled to the signal converter, configured to output the transmission signal according to the converted signal;
- wherein the signal driver configures to a first configuration when the transmitter outputs the transmission signal at the first transmission rate, and the signal driver configures to a second configuration when the transmitter outputs the transmission signal at the second transmission rate.
A transmitter in a network device for outputting a transmission signal at a transmission rate, which is either a first transmission rate or a second transmission rate, the transmitter comprising:
- a signal converter which operates in a first mode or a second mode, and converts an input signal into a converted signal having a plurality of levels;
- and
- a signal driver, coupled to the signal converter, for outputting the transmission signal according to the converted signal;
- wherein the signal converter operates in the first mode if the transmitter outputs the transmission signal in the first transmission rate, and operates in the first mode if the transmitter outputs the transmission signal in the second transmission rate.
A transmitting method used in a transmitter of a network device, the method comprising:
- receiving an input signal;
- performing a level conversion on the input signal to output a first signal;
- determining whether to use a first characteristic or a second characteristic to convert the first signal into a transmission signal according to a transmission rate of the transmitter;
- and
- transmitting the transmission signal according to the transmission rate of the transmitter.
