It integrates two differential-pair channels suitable for e SATA signals up to a 3 Gbps data rate, in pliance 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 mon 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 preemphasis 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. - - - Available in QFN20 (4 x 4 mm) package .. footprint with flow-through pinout - -40 °C to 85 °C operating temperature range Table 1.
