Parade expands USB 3.0 product line with
dual repeater/redriver chip
Parade Technologies Ltd. has announced the expansion of
its USB 3.0 Repeater/Redriver IC product line. Parade's
new PS8720 is a Dual USB 3.0 Repeater/ Redriver that supports
two bi-directional USB ports on a single device. Packed
in 32-pin 3x6mm TQFN package PS8720 is the smallest Dual
Repeater/ Redriver package on the market, claims Parade.
"Parade entered the USB 3.0 market last fall and our
single-port device has been well received by system OEMs,"
explains Jimmy Chiu, VP of Marketing at Parade Technologies.
"The need to support multiple USB ports led us to develop
our new Dual Redriver product, and the OEM requirement for
board layout efficiency led us to utilize the smallest package
possible for this new part."
At 5 Gb/s, USB 3.0--also known as "SuperSpeed"
USB--delivers a ten-fold speed increase over the widely
adopted USB 2.0 "HighSpeed" standard. The transition
to 5Gb/s challenges system designers to maintain signal
integrity in notebook, docking station and other system
designs. PC board traces longer than 5 inches (127mm) from
the USB host controller will require USB Repeater/Redrivers
for signal reconditioning. System boards frequently require
multiple Repeater/Redriver in order to position USB ports
at convenient locations on the system's external interface.
Lowest Power Dual USB 3.0 Repeater/Redriver Available:
The PS8720 includes automatic detection of LFPS (Low Frequency
Periodic Signaling) as well as normal SuperSpeed USB data.
LFPS is used for out-of-band signaling for device initiation
and power management. The device is compliant with USB 3.0
signal specifications for LFPS and SuperSpeed USB data at
5Gbit/s.
Parade is offering two versions of its Dual bi-directional
USB 3.0 Repeater/Redriver. The PS8720A uses a single 1.5V
power supply; the PS8720B uses a single 3.3V power supply.
Parade claims the 1.5V PS8720A is the lowest power Dual
USB 3.0 Repeater/Redriver IC available. Both Parade Dual
Repeater/Redrivers support all four USB 3.0 power management
modes, which allow for power saving, suspend and power down
modes when the device is not active.
USB 3.0 is the Newest Version of the Most Widely Used Interface:
USB has been widely adopted in computers, peripherals and
consumer electronics. Leading market research firms estimate
that more than three billion USB-enabled systems will be
sold this year, increasing to more than four billion per
year by 2012. The USB 3.0 interface is now incorporated
into some personal computer chip sets, and wide chip set
adoption is expected within the next twelve months.
Price and Availability: The PS8720A/B is sampling
now, and production volumes will be available September
2011. Both devices are available in a 3x6mm 32-pin TQFN
package.
The PS8720A/B will be available for $2.00 /ea. in high
volume.
