San Jose, CA, 2005-07-26 - Pericom Semiconductor
Corporation (NASDAQ: PSEM), a worldwide preferred supplier of high-speed integrated circuits and frequency control devices, has developed a new
family of EQX products to help solve signal integrity challenges that design engineers are facing with advanced high-speed designs based on differential
signals in applications like PCI Express.
With the advent of high-speed protocols like the PCI Express serial bus architecture at 2.5Gbps
rates, system designers are confronted with the challenges associated with maintaining eye-pattern signal integrity at the receiver end points. Pericom's
new Re-Driver (PI2EQX4401, PI2EQX4402) and Re-Timer (PI2EQX4410) devices focus on the demands of high-speed serial interfaces in the form of
signal boosters that adjust signal levels based on equalization, pre-emphasis/de-emphasis techniques resulting in the eye-pattern at the receiver end
showing the margins needed to conform to high speed signal protocols including PCI Express, SATA, SAS, and XAUI standards.
"Pericom has mastered the techniques of Pre-emphasis, De-emphasis, and Equalization circuits to reverse the behavior of
"attenuation vs. frequency", in order to compensate the effects, and thereby restore the signals at the end point," said Shaf Rahman,
Director of Marketing for Switch & Interface Products. "PI2EQX4401/02 Re-Driver products apply programmable equalization and De-emphasis
techniques to pre-compensate for the signal attenuation for the transmitted signal. Our PI2EQX4410 Re-Timer product, with its Clock-to-Data Recovery
(CDR) circuitry, gets rid of all the jitter by re-generating the data using a clean local reference clock. The 4410 Re-Timer also applies de-emphasis to the
transmitted signal to reduce ISI induced jitter at the far end of the signal path," Rahman continued.
Key Features:
- 2.5Gbps serial PCIe Repeater/Equalizer with clock buffer
- Programmable Receiver Equalization, Transmitter
De-Emphasis & Amplitude
