Features
• World’s first differential spread spectrum oscillator
• Extremely low cycle-cycle jitter
• <30 ps (typical)
• Wide frequency range
• 1 MHz to 220 MHz
• 220 MHz to 800 MHz (contact SiTime)
• Eight spread selections (31.5KHz modulation rate)
• Center Spread: ±0.25%, ±0.5%, ±1.0%, ±2.0%
• Down Spread: -0.5%, -1.0%, -2.0%, -4.0%
• Low frequency tolerance (Spread = OFF)
• ±25 ppm or ±50 ppm
• Operating voltage
• 1.8V or 2.5 or 3.3 V
• Operating temperature range:
• Industrial, -40°C to 85°C
• Extended Commercial, -20°C to 70°C
• Small footprint
• 5.0 x 3.2 x 0.85 mm
• 7.0 x 5.0 x 0.85 mm
• Pb-free and RoHS compliant
• Ultra-reliable start up and greater immunity from interfer-
ence
PRELIMINARY
1 to 800 MHz High Performance Spread Spectrum Oscillator
Benefits
• Services most PC peripherals, networking, and consumer
applications
• Provides wide range of spread percentage for maximum
electromagnetic interference (EMI) reduction
• Up to -17dB reduction on third hormonic and -12dB on the
fundamental
• Fast time to market due to not needing to redesign the PCB
for EMI reduction
• Factory programmable for ultra-fast lead time
• No crystal or capacitors required
• Eliminates crystal qualification time
• 50%+ board saving space
• Completely quartz-free

An Electronics Engineer's Experience
“工程师是科学家;工程师是艺术家;工程师也是思想家。”一位伟大的工程师曾经提出过这样的一段感言。不错,工程师是利用自然科学来创造工程的人。工程既是物质的也是思想上的。许多不朽的工程,伟大的发明以及出神入化的技术方案,许多人往往只看到了他们的瑰丽,而作为工程师则更应该看到设计的灵魂。因此我们应该深入的理解“工程师也是艺术家和思想家”。工程设计的本身就是一种艺术,也是工程师思想的结晶。一部精密的机械设...
