Abstract
A signal modification circuit is provided for use with multi-mode formatted data in accordance with a common mode component and a high frequency component formatted in accordance with a differential mode. The circuit includes an active module that modifies the high frequency component to generate a modified and enhanced high frequency component at an output thereof. A bypass line interconnects the inputs and outputs of the active module to bypass the active module. A low pass filter is provided along the bypass line blocking passage of the high frequency component along the bypass line.
Claims24
An active signal modification circuit, comprising:
- an input comprising two input lines configured to receive a differential pair signal having a low frequency (LF) component formatted in accordance with a first mode and a HF component formatted in accordance with a second mode;
- a signal modification module, joined to said input, modifying said HF component of said differential pair signal and generating a modified HF component at an output of said signal modification module;
- a bypass line interconnecting said input and said output to bypass said signal modification module;
- and
- a low pass (LP) filter provided along said bypass line blocking said HF component of said differential pair signals.
A signal modification cable assembly, comprising:
- a cable comprising two input lines configured to convey a pair signal having a low frequency (LF) component formatted in accordance with a first mode and a HF component formatted in accordance with a second mode;
- a signal modification module, joined to said cable, modifying said HF component and generating a modified HF component at an output of said signal modification module;
- a bypass line interconnecting said cable and said output to bypass said signal modification module;
- and
- a low pass (LP) filter provided along said bypass line blocking said HF component.
