Description

PI3DPX1207B is the DP-Alt 1.4 (Max 10Gbps) Linear Redriver.  The DP1.4 standard can support 4K2K@120Hz / 25.82 Gbps with 4-channels.

Each of the DP1.4 and USB3.1 Gen2 differential signals can be easily adjustable with equalization, output swing and gain adjustment by either pin or I2C control settings. It can optimize the DP/USB 10Gbps signal performance over a variety of physical mediums by reducing Inter-symbol interference jitters.

Non-blocking linear Redriver can provide 2x better additive jitter performance than the conventional CMOS-based Redriver. Since Linear Redriver does not block the Receiver DFE’s adaptive channel controls, it can natively support DisplayPort Transparent LT(Link Training) without any dependency of the DP-Aux channels listener.

Named as “Trace Loss Canceling” technology, and supports the cascading high-speed link connections between Host and Device. It means multiple linear Redriver can be placed in the link to work seamlessly to compensate high insertion loss.

The Cascading, Low Jitter and Simplicity of Gain adjustment capabilities to extend signal transmission features are an ideal choice for the 8-10Gbps high-speed DP Alt signal integrity solutions.

Signal Integrity - ReDrivers/Repeaters FAQs

Are Pericom PCIe 3.0 ReDrivers compatible with PCIe 1.0 & 2.0?

Yes, Pericom 3.0 ReDrivers PI3EQX8908A, can be used in PCIe 1.0 and 2.0 modes.

Does Pericom PCIe ReDriver™ include a PCIe CLK buffer?

Pericom PCIe 1.0 ReDriver™ does include a PCIe CLK buffer but neither the PCIe 2.0 nor 3.0 ReDriver includes a
PCIe CLK buffer.

Does Pericom provide PCIe ReDriver's simulation model and reference circuit?

Yes,  Please contact your sales representative for simulation model and reference circuit. or contact Pericom Customer Support.

How do I know the PCIe ReDriver™ is already linked up with the CML output device?

Our PCIe 3.0 ReDriver can perform output (ReDriver's TX) side 50-Ohm termination detect. The ReDriver's RX50 pin is asserted high once the device detects the 50-Ohm termination.

 

How do I know the PCIe ReDriver™ is working and signal is passing through the ReDriver IC?

The PCIe ReDriver provides the signal output pin, "SIG", to indicate that signal is passing through the ReDriver.

How long can the PCB trace extend using a Pericom USB3.0 ReDriver™?

Pericom PI3EQX7701 EQ can compensate 5 db and 11db loss (2.5 GHz or 5 Gb/s).

How long the PCB trace can extend using a Pericom PCIe ReDriver™?

Please refer the AN233, page 5 and page 9.

Is Pericom's USB3.0 ReDriver™ compatible with USB2.0?

No. USB 3.0 uses different connect pins from USB 2.0's. The USB 3.0 Standard-B receptacle interfaces are divided into two sets of interfaces: the USB 2.0 interface and the USB 3.0 SuperSpeed interface. The USB 2.0 interface is comprised of pins 1 to 4, and the USB 3.0 SuperSpeed interface is comprised of pins 5 to 9. The figure below shows  the footprint of USB3.0 found in "Universal Serial Bus 3.0 Specification Version 1.0_Page 5-19_Figure5-8".

Is there a replacement for an obsolete part?

Not all obsolete parts will have a direct replacement. However, we recommended that you contact your regional sales office.

Is there any Application Notes for PCIe ReDrivers?

Yes, AN088 and AN233 are Application Notes for PCIe ReDrivers.

Is there any pull up/down resistor needed on Dual Mode DP Source Device on Pin 13 of cable adaptor detect?

1Mohm pull down resistor on Pin 13 is needed on Dual Mode DP Source Device.

What are the types of jitter?

There are several types of jitter, but the main ones are: cycle-to-cycle jitter, period jitter, half period jitter, and peak-to-peak jitter. Jitter terminology can be found in AB36: Jitter Measurement Techniques at Application Brief No. 36 or Application Note No. 27.

What controls are provided by the PCIe ReDriver?

Both I2C and GPIO controls are provided.

What does de-emphasis control mean?

Emphasis control can improve USB3.0 ReDriver's output signal.
The integrated de-emphasis circuitry provides flexibility and improves the integrity of USB3.0 output signal after ReDriver.
The de-emphasis selection table below describes pin strapping options and associated de-emphasis operations. This table can be found in  datasheet, page 3.

What does emphasis control mean?

Emphasis control improves the PCIe ReDriver output signal.

What does EQ control mean?

EQ control can improve the USB3.0 ReDriver's input signal. The integrated equalization circuitry provides flexibility and improves the integrity of the USB3.0 input signal before the ReDriver. The Equalizer Selection table below describes pin strapping options and associated operations of the equalizer. This table can be found in PI3EQX7741AI datasheet, page 3.

What does swing control mean?

Swing control can adjust the ReDriver IC output swing level.

What is cycle-to-cycle jitter?

Cycle-to-cycle jitter is the difference in the clock's period between two consecutive cycles and is expressed in units of + pico-seconds. This is because it can be either leading or lagging from the ideal output waveform.

What is the application suitability comparison between a switch and a logic driver?

A switch is a passive device with C-on and R-on that will attenuate the signal. A logic driver is an active device that will refresh an input signal at output by its active driving ability. Thus, compared to a logic driver, the maximum frequency of an application using a switch is limited by the trace length and the capacitive load. It is recommended to use a logic driver for applications with heavy capacitive load, long trace and high frequency.

What is the impedance range for USB3.0?

The range of the impedance is from 75Ω to 105Ω.

What is the lead finish for Pericom products? What about lead-free?

All Pericom's products that are not lead-free are composed of 85% Sn and 15% Pb. For lead-free products, they are composed of 100% matte Sn. Lead-free products are marked and ordered with the letter "E" suffix at the end of the part number.

What is the minimum input swing level that a Pericom PCIe ReDriver can accept?

The minimum input swing level is shown in the specification "CML input Differential Input Peak-to-peak Voltage" and some ReDrivers can automatically select the input threshold voltage.

What is the significance of the EQ control?

EQ control can improve the PCIe ReDriver input signal.

When the client-side returns a feedback packet to the host side, will Pericom's PCIe ReDriver block the packet or require control?

No, Pericom PCIe ReDriver will not block any PCIe signals. The ReDriver only enhances gains of the data voltage without changing the data. The host always sees the end-point directly. Pericom ReDriver is "100% transparent", which means the "host" and "end-point" do not detect the presence of the ReDriver.

Where can I find Mean Time Before Failure (MTBF) or Failures In Time (FIT) values for Pericom products?

FIT and MTBF data can be found at Pericom's Quality webpage.

Where can I find the information on your Pb-free and "Green" packaging?

Lead (Pb)-Free and Green information can be found on individual datasheets or Pb-Free & Green Page.
