LVPECL / HCSL / LVDS / CML
1 to 220 MHz High Performance Spread Spectrum Oscillator
Features
• World’s first differential spread spectrum oscillator
• Extremely low cycle-cycle jitter
• As low as10 ps (typical)
• Wide frequency range
• 1 MHz to 220 MHz
• 220 MHz to 800 MHz (contact SiTime)
• Eight spread selections (31.5 KHz modulation rate)
• Center Spread: ±0.25%, ±0.5%, ±1.0%, ±2.0%
• Down Spread: -0.5%, -1.0%, -2.0%, -4.0%
• For -0.25% and ±0.125% contact SiTime
• Low frequency stability (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 0.75 mm
• 7.0 x 5.0 x 0.90 mm
• Pb-free and RoHS compliant
• Ultra-reliable start up and greater immunity from inter-
ference
Benefits
• Services most PC peripherals, networking, and consumer
applications
• Provides wide range of spread percentage for maximum
electromagnetic interference (EMI) reduction
• Up to -17 dB reduction on third homonic 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 load capacitors required
• Eliminates crystal qualification time
• 50%+ board saving space
• Completely quartz-free
Applications
• PCI-Express
• USB 3.0
• Fully Buffered DIMM
• Blade Server
• Router
• System Clock
• Networking and Computing
• Automotive
• Industrial
