The Ready LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the 3.3 volt 
supply through an appropriate current limiting resistor. The LED and the current limiting resistor are external to the drive. See 
the next table for the output characteristics of the LED drive signals.  

11.5.2 Differential signals

The drive SAS differential signals comply with the intra-enclosure (internal connector) requirements of the SAS standard.

The table below defines the general interface characteristics

SAS-2 S

PECIFICATION COMPLIANCE

Seagate SAS-2 drives are entirely compatible with the latest SAS-2 Specification (T10/1760-D) Revision 16.

The most important characteristic of the SAS-2 drive at 6Gb/s is that the receiver is capable of adapting the equalizer to 
optimize the receive margins. The SAS-2 drive has two types of equalizers: 
1. A Decision Feedback Equalizer (DFE) which utilizes the standard SAS-2 training pattern transmitted during the SNW-3 

training gap. The DFE circuit can derive an optimal equalization characteristic to compensate for many of the receive 
losses in the system.

2. A Feed Forward Equalizer (FFE) optimized to provide balanced receive margins over a range of channels bounded by 

the best and worst case channels as defined by the relevant ANSI standard.
