The GN1406 extends the reach and robustness of high-speed serial links by compensating for losses in the transmission medium and resetting the jitter budget. Each high-speed input interface includes an integrated high input jitter tolerant retimer circuit with adjustable equalization. The GN1406 high-speed serial output interface features very low jitter and allows for amplitude adjustment through the use of a serial control interface. De-emphasis levels can also be set to compensate for transmission losses. Each channel in the GN1406 can be independently configured or powered down. A turn-key Reference Design Kit is available including schematics and PCB design database.

From a signal integrity perspective, CATx cable is challenging due to high losses and crosstalk caused by lack of shielding. The high gain equalization function of the GN1406 overcomes the cable insertion loss. The retimer mitigates this further while rejecting crosstalk induced jitter. Due to the need to communicate 3 or 4 sideband signals in addition to high-speed data and clock, another challenge for this application is the limited number of signal pairs available on a single CATx cable. By using a small Microcontroller at each end, it is possible to multiplex the low-speed sideband signals so that only a single twisted pair is required.
