Ultra Series Crystal Oscillator Si564 Data Sheet Ultra Low Jitter I2C Programmable XO (90 fs), 0.2 to 3000 KEY FEATURES MHz I2C programmable to any frequency from 0.2 to th The Si564 Ultra Series oscillator utilizes Skyworks Solutions advanced 4 3000 MHz with < 1 ppb resolution generation DSPLL technology to provide an ultra-low jitter, low phase noise Ultra low jitter: 90 fs RMS Typ (12 kHz 20 clock at any output frequency. The device is user-programmed via simple I2C MHz) commands to provide any frequency from 0.2 to 3000 MHz with <1 ppb resolution Configure up to 4 pin-selectable startup and maintains exceptionally low jitter for both integer and fractional frequencies frequencies across its operating range. The Si564 offers excellent reliability and frequency I2C interface supports 100 kbps, 400 kbps, and stability as well as guaranteed aging performance. On-chip power supply filtering 1 Mbps (Fast Mode Plus) provides industry-leading power supply noise rejection, simplifying the task of Excellent PSNR and supply noise immunity: generating low jitter clocks in noisy systems that use switched-mode power sup- 80 dBc Typ plies. The Si564 has a dramatically simplified supply chain that enables Skyworks 3.3 V, 2.5 V, and 1.8 V V supply operation DD to ship custom frequency samples 1-2 weeks after receipt of order. Unlike a from the same part number traditional XO, where a different crystal is required for each output frequency, the LVPECL, LVDS, CML, HCSL, CMOS, and Dual Si564 uses one simple crystal and a DSPLL IC-based approach to provide the CMOS output options desired output frequency. The Si564 is factory-configurable for a wide variety of 2.5x3.2, 3.2x5, 5x7 mm package options user specifications, including startup frequency, I2C address, output format, and OE pin location/polarity. Specific configurations are factory-programmed at time Samples available with 1-2 week lead times of shipment, eliminating the long lead times associated with custom oscillators.
