The MAX4952B dual-channel redriver is designed to redrive one full lane of SAS or SATA signals up to 6.0Gbps and operates from a single +3.3V supply. The MAX4952B is designed for commercial SAS or SAS/SATA applications, such as servers.

The MAX4952B features independent output boost and enhances signal integrity at the receiver by re-establishing full output levels. SAS/SATA out-of-band (OOB) signaling is supported using high-speed amplitude detection on the inputs and squelch on the corresponding outputs.

Inputs and outputs are all terminated in 50Ω internally and exhibit excellent return loss.

The MAX4952B is available in a small, 20-pin, 4.0mm × 4.0mm TQFN package with flow-through traces for ease of layout. This device is specified over the 0°C to +70°C operating temperature range.

Product Detail

The MAX4952B evaluation kit (EV kit) provides a proven design to evaluate the MAX4952B dual-channel redriver. The EV kit contains four sections: application circuit, characterization circuit, and two sets of calibration traces.

The application circuit is designed to demonstrate the MAX4952B IC's use in redriving SATA and SAS signals. This section of the EV kit operates from an external +5V supply that is regulated by an on-board LDO to +3.3V, which powers the MAX4952B (U1) device. All traces in the application circuit are 100Ω differential controlled-impedance traces.

The characterization circuit is provided for eye diagram evaluation using SMA connectors and 50Ω controlled-impedance traces. This section is powered by an external +3.3V power supply.
