EMI-reducing differential oscillator

SiTime has introduced the EMI-reducing differential oscillators for PCI Express or FB-DIMM applications. High-volume applications can employ the SiT9002AI oscillator to provide clocks for PCI-Express or FB-DIMM and designers can use the built-in spread spectrum technology to reduce EMI (electro-magnetic interference) to up to 16dB. The spread spectrum technology also allows designers to pass compliance testing without lengthy delays, expensive board redesign, or shielding. The oscillator offers many features that are compliant with PCI-Express and FBDIMM timing standards. The differential outputs are configured to comply with the HCSL (High-Speed Current Steering Logic) specification. The device offers cycle-cycle jitter of 15ps and total frequency stability of ±50 PPM over the industrial temperature range of -40 to +85°C. The oscillator features power supply voltage of 3.3 or 2.5V and output frequency of 100 and 200MHz. The device is offered in industry-standard footprints of size 7.0x5.0x0.9mm or 5.0x3.2x0.75mm and possesses OE (output enable) or SD (spread disable).
