The IDT XAUI Repeater Family offer the industry a blend of top analog performance, lower power, and the most system-level features in signal repeaters optimized for demanding 1.25 Gbps to 6.25 Gbps applications in computing, storage, and communications.
Benefits of IDT XAUI repeaters:
- Extends maximum cable length to over 10 meters and trace length over 65 inches in cabled XAUI applications
- Speeds up system design time by allowing usage of longer trace and cable lengths
- Minimizes bit error rate (BER)

Industry-leading XAUI Signal Repeaters
IDT’s XAUI repeaters are 1.25 Gbps to 6.25 Gbps ICs that recondition high-speed serial data streams. The devices feature IDT EyeBoost™ technology that compensates for cable and board trace attenuations and ISI jitter, thereby extending connection reach. The devices are optimized for XAUI high-speed, serial differential data streams and are able to process up to 6.25 Gbps transmission rates. IDT offers XAUI repeaters with 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 XAUI repeaters provide global programmable settings, including termination resistance values and transfer modes.
All modes of active data transfer by the XAUI 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, IDT’s PCIe repeaters consume only 10 mW per channel (40 mW for 4-ch device, and 80 mW for 8-ch device).
IDT’s XAUI signal repeaters are ideal for a myriad of applications using a wide combination of cables and board trace materials, including telecommunications, networking, and 10 GbE systems.

About XAUI Repeaters
High-speed signals can deteriorate to unacceptable levels by the time they reach end receivers, due to transmitter, receiver, and channel characteristics. XAUI 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.
