Abstract
According to one embodiment, a semiconductor integrated circuit includes an equalizer circuit and a toggle detection circuit. The equalizer circuit is configured to amplify an input signal that are externally input to output an amplified signal as a first signal. The toggle detection circuit is configured to detect toggling of the first signal and to dynamically switch a gain of the equalizer circuit based on whether or not toggling of the first signal is detected.
Claims19
A semiconductor integrated circuit comprising:
- an equalizer circuit configured to amplify an input signal that is externally input to output an amplified signal as a first signal, the input signal having a period of time in which toggling stops;
- and
- a toggle detection circuit configured to detect whether or not the first signal is toggling and to dynamically switch a gain of the equalizer circuit based on whether or not toggling of the first signal is detected, wherein
- a first gain of a low frequency band of the equalizer circuit while the toggle detection circuit detects the toggling of the first signal is lower than a second gain of the low frequency band of the equalizer circuit while the toggle detection circuit does not detect the toggling of the first signal.
