Original Press Release:



Pericom Announces New Low-Jitter, High-Frequency Crystal Oscillator Family for High-Speed Serial Applications in 10GbE, PON, and SAS



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 / / - 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.

Low Jitter

XP oscillators contain no internal PLL frequency multiplier; therefore output jitter is very low.

Tight Stability

XP oscillators use BAW (bulk acoustic wave) crystal devices, thereby achieving better stability performance than oscillators based on high frequency SAW (surface acoustic wave) designs.

Low Power Consumption

XP CMOS oscillators consume an unprecedented low level of current; only 25mA max (2.5V) and 30mA max (3.3V) significantly lower than other competing technologies.

Pricing & Availability

OEM 100K prices range from $1.30 to $3.00 depending on series, frequency and stability. Samples and production quantities are available now.
