SAS / SATA 6G Signal Repeaters

The IDT SATA / SAS repeater family offers the industry a blend of top analog performance, lower power, and the most system-level features in signal repeaters optimized for demanding 1.5Gbps to 6G applications in computing, storage, and communications.

Benefits of IDT SAS / SATA repeaters:

  • Extends maximum cable length to over 10 meters and trace length over 65 inches in cabled SAS / SATA applications
  • Speeds up system design time by allowing usage of longer trace and cable lengths
  • Minimizes bit error rate (BER)

Industry-leading SATA and SAS Repeaters

IDT offers 1.5 Gbps to 6 Gbps SATA and SAS repeaters featuring EyeBoost™ technology that compensates for cable and board trace attenuations and ISI jitter, thereby extending connection reach. The devices offer four or eight channels, each consisting of an input equalizer and amplifier, signal detection with glitch filter, as well as programmable output swing, slew rate, and de-emphasis with delay control. All of these features are user-programmable to allow for application-specific optimization.

In addition to the per-channel programmable features, IDT’s SATA / SAS repeaters provide global programmable settings, including termination resistance values and transfer modes.

All modes of active data transfer by the SATA / SAS repeater are designed for minimal power consumption. Also, a wide range of power-reducing modes enable the user to eliminate power of unused blocks, including a shutdown mode. In full shutdown mode, IIDT’s PCIe repeaters consume only 10 mW per channel (40 mW for 4-ch device, and 80 mW for 8-ch device).

IDT’s SATA / SAS repeaters are ideal for a myriad of applications using a wide combination of cables and board trace materials, including blade servers, rack servers, SAS / SATA instrumentation, storage systems, and cabled SAS / SATA devices.

About SATA / SAS Repeaters

High-speed signals can deteriorate to unacceptable levels by the time they reach end receivers, due to transmitter, receiver, and channel characteristics. SATA / SAS repeaters ensure minimized jitter and maximized eye opening at the target receiver by compensating for cable and PCB trace attenuation and ISI jitter. This is accomplished by boosting the transmitted signal, by equalizing the received signal, or by doing both when either option by itself is not sufficient due to channel length or due to discontinuities generated by vias and connectors.
