Abracon ASxxx Series of
High Performance MEMS Differential Clock Oscillator
Features
ASxxx Series of devices are miniature MEMS based, PLL clock oscillators optimized to meet the requirements of high
speed serial data communication channels. These differential devices are available in single and dual output formats
including CMOS, LV-PECL, LVDS, and HCSL.
What the ASxxx can do for your design…..
• Devices are available in standard pin-pin compatible
[7.0 x5.0mm], [5.0x3.2mm], [3.2x2.5mm], and
[2.5x2.0mm] footprints.
• Devices are Lead Free & RoHS compliant.
• Jitter optimized for high speed serial data formats.
• High Reliability, with 20 times better MTTF than
quartz oscillators
• Devices operate from +2.5, to +3.6 Volt supplies
• -40 to +85C operating temperature range, and
extended Automotive Grade temperature stability at
-55 to +125°C, ±25ppm
• Multiple output formats: CMOS, LVPECL, LVDS,
HCSL, including Dual Output configurations.
• High Stability with ± 10ppm, ±25ppm, ±50 ppm
available.
• Short lead Time: 2 weeks
• Shock & Vibration Immunity MIL-STD-883
• 50 dBc Power Supply Rejection Ratio
• Field programmable production devices are available
The ASxxx series saves PCB area. Combine a small device
footprint and minimal external components to get the
smallest solution footprint.
The ASxxx series is optimized to exceed Jitter requirements
of high speed serial data formats. Integrated jitter 100KHz
-20MHz < 400fs, and 200KHz – 20 MHz < 300 fs.
ASxxx series is more cost efficient vs. quartz competitors.
As device dimensions shrink, quartz resonator costs
increase. The 0.2 mm2 MEMS device cost decreases with
package size.
