This document is the user manual for STA1102R. It introduces the features of this product, including supporting eSATA data rate of 1.5Gbps and 3Gbps, supporting complete eSATA bus of two 2-wire differential-pair channels, single operating supply (VCC) range of 3.3V ± 10%, low power mode, 100Ω CML I/Os, eSATA hot-plug capable, low capacitance, 1-bit input equalizer regenerates the receiver attenuated signal, 1-bit adjustable pre-emphasis and driver to drive the transmitter outputs over long PCB track lengths, low output skew and jitter, low ground bounce, -40°C to 85°C operating temperature range, etc.
The STA1102R is a serial data signal re-driver designed for eSATA signals up to a 3 Gbps data rate, complying with the SATA rev 2.6 specification. It integrates two differential-pair channels and features an input detector for output squelch functionality to monitor input signal levels. The device supports a single 3.3 V operating supply and includes low power modes to reduce consumption when the device is inactive.
| Data rate | 1.5 Gbps and 3 Gbps |
|---|---|
| Supply voltage | 3.3 V + 10% |
| Operating temperature | -40 °C to 85 °C |
| Package | QFN20 (4 x 4 mm) |
