SiT9002 LVPECL / HCSL / LVDS / CML 1 to 220 MHz High Performance Spread Spectrum Oscillator Features Benefits Worlds first differential spread spectrum oscillator Services most PC peripherals, networking, and consumer applications Extremely low cycle-cycle jitter Provides wide range of spread percentage for maximum As low as10 ps (typical) electromagnetic interference (EMI) reduction Wide frequency range Up to -17 dB reduction on third homonic and -12dB on the 1 MHz to 220 MHz fundamental 220 MHz to 800 MHz (contact SiTime) Fast time to market due to not needing to redesign the PCB Eight spread selections (31.5 KHz modulation rate) for EMI reduction Center Spread: 0.25%, 0.5%, 1.0%, 2.0% Factory programmable for ultra-fast lead time Down Spread: -0.5%, -1.0%, -2.0%, -4.0% No crystal or load capacitors required For -0.25% and 0.125% contact SiTime Eliminates crystal qualification time Low frequency stability (Spread = OFF) 50%+ board saving space 25 ppm or 50 ppm Completely quartz-free Operating voltage Applications 1.8V or 2.5 or 3.3 V PCI-Express Operating temperature range: USB 3.0 Industrial, -40C to 85C Fully Buffered DIMM Extended Commercial, -20C to 70C Blade Server Small footprint Router 5.0 x 3.2 x 0.75 mm System Clock 7.0 x 5.0 x 0.90 mm Networking and Computing Pb-free and RoHS compliant Automotive Ultra-reliable start up and greater immunity from inter- ference Industrial Block Diagram Pinout SiTime Corporation 990 Almanor Avenue Sunnyvale, CA 94085 (408) 328-4400 www.sitime.com Rev. 1.11 Revised September 27, 2016 SiT9002 LVPECL / HCSL / LVDS / CML 1 to 220 MHz High Performance Spread Spectrum Oscillator Pin Description Pin No. Name Pin Description 1 ST/OE/SD Input Standby or Output Enable pin for OUT+ and OUT-. OE: When High or Open : OUT+ and OUT- = active When Low : OUT+ and OUT- = High Impedance state ST: When High or Open : OUT+ and OUT- = active When Low : OUT+ and OUT- = Output is low (weak pull down), oscillation stops SD: Spread Disable - disables spread spectrum When High or Open : Spread Spectrum modulation = active When Low : Spread Spectrum modulation = Off 2 NC NA No connect pin, leave it floating. 3 GND Power VDD power supply ground. Connect to ground 4 OUT+ Output 1 to 220 MHz programmable clock output.
