STA1102R 3 Gbps, 2 differential-pair channel eSATA signal re-driver

The STA1102R is a serial data signal re-driver. It integrates two differential-pair channels suitable for eSATA signals up to a 3 Gbps data rate, in compliance with the SATA rev 2.6 specification.

An input detector is available at each channel, which constantly monitors the input signal level for output squelch functionality. If the detected differential input is below a defined threshold, the output is biased to the common mode voltage.

High-speed data paths and the flow-through pinout minimize internal device jitter and simplify board layout. The integrated input equalizer improves signal integrity at the receiver due to effects from lossy cables. A 1-bit adjustable pre-emphasis is also integrated to drive the transmitter outputs over long PCB track lengths.

The device can be set to a low-power mode by disabling the output current drivers through the EN pin
