Also, a wide range of power-reducing modes enable the user to eliminate power of unused blocks, including a shutdown mode. Tundra Semiconductor VadaTech Inc. Switch between DisplayPort and HDMI port using a single video switch while maintaining signal integrity over a cable length of 30 meters. Each video color channel RGB can range from six to sixteen bits of depth, and up to eight audio channels of bit, KHz uncompressed PCM audio can be sent. All modes of active data transfer by the PCIe repeater are designed for minimal power consumption.

PCI Express® (PCIe) Signal Repeater & Redriver

For the DisplayPort signals red and the auxiliary channel link training pinkthe linear redriver differs from a regular redriver or retimer by adding neither equalization EQ nor de-emphasis DE. The new devices reddiver enhanced with an easier adjustment for the redriver settings and a wider range of channel lengths any setting.

About PCIe Retimers High-speed signals can deteriorate to unacceptable levels by the time they reach end receivers, due to transmitter, receiver, and channel characteristics. Automation Testing Market Worth Multicore Developers Conference N.

Figure 5 shows how redrivers or retimers can be used to improve the SI problems noted in Figures 2 and 3. Verizon Wireless VersaLogic Corp.

Since all of these features are user-programmable, they allow for application-specific optimization.

Advanced Micro Peripherals Inc. Toshiba Touit Trenton Technology Inc. Based upon this input, limiting redrivers add boost at each stage in the channel, automatically adjusting via programmable EQ and pre-emphasis if link training does not succeed.

According to the company, the family provides cost-effective and protocol-compliant solutions to extend high speed channels on a platform with pciie adjustment time.

Giada Global Information, Pxie. This unique separation between protocol and the assumed-to-work channel can be a strong benefit for DP installations while simultaneously creating challenges for hardware designers. Other features are per channel adjustments, flow through pinouts, and small TQFN packages.

Switch between DisplayPort and HDMI port using a single video switch while maintaining signal integrity over a cable length of 30 meters. The laptop and cable designers can program the linear redriver to the notional channel conditions via pin-strapping or in-system I2C.

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.

Cascade connections with limiting-type redrivers cause overshoot and magnify the SI challenge. These cables are not fantasy; they are readily available on Amazon, Monoprice and other popular online sites.

Embedded within the active cable itself, another redriver will again respond to the same link training signals and add additional EQ and DE. These low power, high performance, single- and dual-channel B devices extend both USB3. Digital designers understand that at Gigabits per second Gbps speeds, they need to pay careful attention to signal integrity. On the right in Figure 5 is a simple retimer, similar to a redriver but with the ability to recover, resynchronize and retransmit signals with the embedded clock.


Extensive software is available to support test and debug, including a PC utility for setting and saving redrivver configuration, and an eye capture tool supporting remote in-field diagnosis. Finally, at the destination end, the receiving redriver will again add EQ and DE. Redriver, Retimer, Linear Redriver Instead of using limiting redrivers or retimers, the solution to this problem is to use a linear redriver that is most rediver, independent of the AUX channel and programmed by the hardware designer in advance based upon the known channel s characteristics.

The serial bus also allows for inspection of the numerous status registers. A significant advantage of DP for high resolution video is that fewer pins channel pairs are needed redriveer video and audio, and that new capabilities can be added to DP without undue consideration for the physical channel interface.
