Programmable, Rich Feature Set Offers High Performance and Flexibility

SUNNYVALE, Calif. – May 22, 2012 – SiTime Corporation, an analog semiconductor company that is revolutionizing the $6 billion timing market with Silicon MEMS solutions, today announced that the Xilinx Virtex®-7 FPGA, Kintex-7 FPGA and Zynq-7000 EPP evaluation kits are using SiTime’s programmable high-performance MEMS oscillators.

Xilinx uses SiTime’s SiT9102 differential oscillator as the system clock and the SiT8102 oscillator as the HDMI reference clock on the Virtex-7 FPGA VC707 Evaluation Kit and the Kintex-7 FPGA KC705 Evaluation Kit. In addition, the Zynq-7000 dual ARM processor evaluation kit uses the same two oscillators plus an additional SiT8103 single-ended oscillator.

“Xilinx is committed to providing our customers with very high performance solutions that are flexible, configurable and accelerate design cycles,” said Steve Logan, analog marketing manager at Xilinx. “SiTime’s programmable MEMS oscillators offer unmatched flexibility and configurability, which complements our FPGAs. We had great success in using SiTime’s MEMS oscillators on our previous generation kits and are expanding their usage on all our 28nm 7 series development platforms.”

“Xilinx and SiTime are market leaders in their respective fields and we share a common goal – to provide best-in-class programmable solutions that accelerate customers’ design cycles and improve their system reliability,” said Piyush Sevalia, VP of marketing at SiTime. “Our flexible timing solutions deliver unique features and reliability that is ten times better than legacy quartz timing products. This is one more example of how SiTime’s revolutionary MEMS technology and advanced analog design is displacing quartz and driving the electronics industry’s move to MEMS-based timing.”

About the SiT910x and SiT810x oscillators

SiTime oscillators are designed with a programmable architecture that offers a wide range of features with fast configurability and ultra short lead-time. The SiT9102 has a differential output with programmable LVPECL, LVDS, HCSL and CML signaling levels. The SiT8102 and SiT8103 high performance oscillators have LVCMOS and LVTTL outputs. All devices offer the following features and benefits.

  • Very high-frequency stability, 25 PPM over the industrial temperature range
  • Wide operating frequency range (SiT9102 – 1 to 220 MHz; SiT8102 – 1 to 200MHz and SiT8103 – 1 to 110MHz) with 5 decimal places of accuracy to easily program custom frequencies
  • 1.8V, 2.5V or 3.3V operation to support a range of FPGAs/processors and eliminate level translation components
  • Industry standard footprints in 5032 and 7050 packages; plus 2520 and 3225 packages for the SiT8102 and SiT8103
  • Outstanding silicon reliability of 500 million hours MTBF (10 times better than quartz)
  • 50,000 g shock and 70 g vibration resistance (10 times better than quartz)
  • All devices are in production and are available with fast lead-time of 3 to 5 weeks
