Best price/performance combination for high frequency timing reference of up to 220MHz for the growing networking, storage and broadband access markets

SAN JOSE, Calif. , Feb. 2 /PRNewswire-FirstCall/ -- Pericom Semiconductor Corporation (Nasdaq: PSEM) a worldwide preferred supplier of products for timing, signal conditioning and serial connectivity, today announced in conjunction with Designcon, production availability of an industry-first family of low-jitter, low-power, high-frequency crystal oscillators developed using Pericom's patented XP technology. This technology uses a unique quartz-and-silicon integration technology to offer very low-jitter, non-PLL based oscillators covering the challenging 150MHz - 220MHz frequency spectrum. The new product family addresses cost and performance sensitive requirements of high-growth serial connectivity applications which include 10-Gigabit Ethernet (10GbE), Passive Optical Networks (PON), and Serial Attached SCSI (SAS).

"According to market analyst data (Dell'Oro - July '08, Gartner - July '07, IDC - 2007), total shipments of 10GbE, PON, and SAS2 will exceed 60 Million ports by 2012," said Kay Annamalai , Pericom's senior director of marketing for timing products. "Our unique technology creates a price point that addresses a significant portion of this growing market. Our cost, performance and reliability advantage is achieved with use of our vertically integrated lower-frequency crystal, in-house IC, module design and manufacturing capability."

The 2.5V/3.3V SX/SN series and 3.3V SD/SH series of XP crystal oscillators (XO) feature the very latest in oscillator circuit design techniques. Based on a proprietary patented technology that combines Pericom's IC silicon technology and Saronix-eCera quartz technology, the XP oscillators are designed for much improved reliability and lower phase jitter (0.25ps rms typical) for high-frequency 2.5V & 3.3V CMOS/PECL clock applications. The product is drop-in compatible with existing Overtone, SAW, and PLL-based oscillator solutions in 4-pin 5x7mm (2.5V/3.3V SX CMOS Series), 6-pin 5x7mm (2.5V/3.3V SN PECL) and 6-pin 3.2x5mm (3.3V SD PECL Series) packages.

Key Features & Benefits

Exceptional Reliability

The patented XP clock circuit technology integrated on Pericom Silicon allows a thicker crystal than those used in traditional overtone circuits, thereby enabling improved long-term reliability and fewer failures than traditional overtone oscillators.
