The MAX14970 dual-channel buffer with input equalization and preemphasis is ideal to redrive internal serial-ATA (SATA) 1i, 2i, and 3i signals as well as eSATA 1m and 2m signals. The device features high electrostatic discharge (ESD) ±8kV Human Body Model (HBM) protection. The device can be placed near a SATA connector on the motherboard to overcome board losses and guarantee SATA compliance. The device is SATA specification version 3.0 (gold standard) compliant and can also be pin-configured for SATA specification version 2.6 (gold standard) compliance.

The device features hardware SATA-drive cable detection that automatically places the device into a standby mode that consumes less than 20μA (typ) standby current when no drive is connected. In addition, the device features an independent channel dynamic power-down mode where power consumption is reduced when no input signal is present. The device maintains output common-mode levels to meet internal SATA version 3.0 standards and prevent delays when coming out of low-power mode. The device preserves signal integrity at the receiver by reestablishing full output levels and reducing the total system jitter (TJ) by providing equalization. The device features channel-independent digital preemphasis controls to drive SATA outputs over longer trace lengths to meet internal SATA specifications. SATA out-of-band (OOB) signaling is supported using high-speed out-of-band signal detection on the inputs, and squelch on the corresponding outputs. Inputs and outputs are all internally 50Ω terminated and must be AC-coupled to the SATA controller IC and SATA device.

The device operates from a single +3.3V (typ) supply, is available in a small, 4mm x 4mm TQFN package with flow-through traces for ease of layout, and is specified over the extended -40°C to +85°C operating temperature range.

Product Detail

The MAX14970 evaluation kit (EV kit) provides a proven design to evaluate the MAX14970 dual-channel buffer. The EV kit contains four sections: an application circuit, characterization circuit, and two sets of calibration traces.
The application circuit is designed to demonstrate the device’s use in redriving serial-ATA (SATA) signals and SATA cable detection. This section of the EV kit operates from an external +5V supply that is regulated by an onboard LDO to +3.3V, which powers the 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.
