Low-jitter, 150-220MHz crystal oscillator for high-speed communication applications

Pericom Semiconductor has announced in conjunction with Designcon, production availability of the new family of low-jitter, low-power, high-frequency crystal oscillators developed using Pericom's 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 performance sensitive requirements of serial connectivity applications which include 10-Gigabit Ethernet (10GbE), Passive Optical Networks (PON), and Serial Attached SCSI (SAS).

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. Its based on the technology that combines Pericom's IC silicon technology and Saronix-eCera quartz technology.

Key features & advantages are:

1. Reliability: The 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.
2. Low Jitter: XP oscillators contain no internal PLL frequency multiplier; therefore output jitter is very low
3. Lower phase jitter (0.25ps rms typical) for high-frequency 2.5V & 3.3V CMOS/PECL clock applications.
4. 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.
5. Low Power Consumption: XP CMOS oscillators consume a low level of current; only 25mA max (2.5V) and 30mA max (3.3V) significantly lower than other competing technologies.
6. 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.

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