Semtech GN1406
四通道多速率中继器/重定时器
The GN1406 is a quad repeater/retimer designed for 2.5Gbps and 5.0Gbps or 3.125Gbps and 6.25Gbps communications. 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.
