Ultra Series Crystal Oscillator Si544 Data Sheet Ultra Low Jitter I2C Programmable XO (150 fs), 0.2 to 1500 MHz th The Si544 Ultra Series oscillator utilizes Silicon Laboratories advanced 4 KEY FEATURES generation DSPLL technology to provide an ultra-low jitter, low phase noise clock at any output frequency. The device is user-programmed via simple I2C programmable to any frequency from 0.2 to I2C commands to provide any frequency from 0.2 to 1500 MHz with <1 ppb 1500 MHz with < 1 ppb resolution resolution and maintains exceptionally low jitter for both integer and fraction- Very low jitter: 150 fs Typ RMS (12 kHz 20 MHz) al frequencies across its operating range. The Si544 offers excellent reliabili- ty and frequency stability as well as guaranteed aging performance. On-chip Configure up to 4 pin-selectable startup frequencies power supply filtering provides industry-leading power supply noise rejection, I2C interface supports 100 kbps, 400 kbps, and 1 simplifying the task of generating low jitter clocks in noisy systems that use Mbps (Fast Mode Plus) switched-mode power supplies. The Si544 has a dramatically simplified sup- Excellent PSNR and supply noise immunity: 80 ply chain that enables Silicon Labs to ship custom frequency samples 1-2 dBc Typ weeks after receipt of order. Unlike a traditional XO, where a different crystal 3.3 V, 2.5 V and 1.8 V V supply operation from DD is required for each output frequency, the Si544 uses one simple crystal and the same part number a DSPLL IC-based approach to provide the desired output frequency. The LVPECL, LVDS, CML, HCSL, CMOS, and Dual Si544 is factory-configurable for a wide variety of user specifications, includ- CMOS output options ing startup frequency, I2C address, output format, and OE pin location/ 2.5x3.2, 3.2x5, 5x7 mm package footprints polarity. Specific configurations are factory-programmed at time of shipment, Samples available with 1-2 week lead times eliminating the long lead times associated with custom oscillators.
