Mon, 02/02/2009 - 5:55am

Pericom SX/SN/SD/SHCovering from 150 MHz to 220 MHz, Pericom Semiconductor’s 2.50-V and 3.30-V SX and SN Series, and 3.30-V SD and SH Series XP crystal oscillators demonstrate a typ. phase jitter of 0.25 ps rms for CMOS and PECL clock applications, respectively. The components present peak-to-peak jitter of 40 ps, max. power consumption of 25 mA at 2.50 V and 30 mA at 3.30 V, stability from ±20 ppm to ±50 ppm, and a selectable frequency option to use half of the frequency. The product is drop-in compatible with existing Overtone, SAW, and PLL-based oscillator solutions in 4-pin 5-mm × 7-mm (2.50-V/3.30-V SX CMOS Series), 6-pin 5-mm × 7-mm (2.50-V/3.30-V SN PECL) and 6-pin 3.20-mm × 5-mm (3.30-V SD PECL Series) packages. Applications include 10-Gigabit Ethernet (10GbE), Passive Optical Networks (PON), and Serial Attached SCSI (SAS). From $1.30 to $3.00.
