Description

SATA REDRIVER 6GBPS TQFN-20
The MAX14970 dual-channel buffer with input equaliza- tion 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 moth- erboard 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 receiv­ er by reestablishing full output levels and reducing the total sys- tem jitter (TJ) by providing equalization. The device fea- tures 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 cor- responding 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 -40ºC to +85ºC operating temperature range.
