Parade Technologies Introduces 2-lane 8Gb/s PCI Express and SATA Redriver

Posted May 17th, 2016

Bi-directional 2-lane redriver ideal for new M.2 SSD and other high speed peripheral applications

Santa Clara, Calif.— 17 May 2015 —Parade Technologies, Ltd. (Taiwan OTC: 4966.TWO), a leading high-speed interface IC supplier, today announced another addition to the company’s high-speed signal integrity product lineup.  The PS8559 is a new high-speed digital interface redriver that supports both PCIe (PCI Express) and SATA.  This IC features four redriver channels enabling the support of two bi-directional lanes.  The PS8559 handles PCIe up to 8Gb/sec and SATA up to 6Gb/sec.

By supporting PCIe and SATA, the PS8559 is ideal for the SATA Express interface which utilizes both of these interface standards and is used for PC storage devices.  The support of two PCIe lanes also makes the PS8559 well suited for the newer M.2 interface used in PCs and laptops.  The M.2 interface, which supports M.2 periphery cards such as the high transfer rate M.2 SSD cards, supports two or four PCIe lanes.  Other applications for the PS8559 include server-class PCIe SSD, and PCIe cabling.

While the increased 8Gb/sec transfer rate of PCIe brings a welcomed performance increase, it also presents challenges to system designer.  At this speed, the allowable distance through PCB traces and other interconnect becomes limited because of signal distortion.  This is where the PS8559 come into play; placed along the signal path, or near the end of the path by the peripheral connector, it cleans up and re-transmits the PCIe or SATA signal, both increasing data transmission reliability and enabling system design flexibility.  For each of the four PCI Express or SATA channels, the PS8559 integrates a receiver, an adaptive filter that removes distortion, and a transmitter.

“We have a lot of proven and proprietary IP in the area high speed data redrivers,” said Jimmy Chiu, Executive VP of Marketing at Parade Technologies.  “Parade is the number one supplier of high speed data redrivers.  Platform developers and top tier OEMs depend on us for high speed data bus solutions.  Because multi-lane PCIe implementations are becoming more common, the PS8559 ads a nice option to our signal integrity product line.”

The PS8559 is optimized for low power and includes an automatic power saving mode, making it well suited for portable systems.


The PS8559 is sampling now, in two versions.  The PS8559A supports a single supply of 1.2, 1.35, or 1.5 Volts.  The PS8559B supports a single 3.3 Volt supply.  Both versions are packaged in a small 4x6mm QFN Halogen-free RoHS package.
