Si544 Data Sheet
Ultra Low Jitter I2C Programmable XO (150 fs), 0.2 to 1500 MHz
The Si544 Ultra Series
oscillator utilizes Silicon Laboratories’ advanced 4
th
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 commands to provide any frequency from 0.2 to 1500 MHz with <1 ppb
resolution and maintains exceptionally low jitter for both integer and fraction-
al frequencies across its operating range. The Si544 offers excellent reliabili-
ty and frequency stability as well as guaranteed aging performance. On-chip
power supply filtering provides industry-leading power supply noise rejection,
simplifying the task of generating low jitter clocks in noisy systems that use
switched-mode power supplies. The Si544 has a dramatically simplified sup-
ply chain that enables Silicon Labs to ship custom frequency samples 1-2
weeks after receipt of order. Unlike a traditional XO, where a different crystal
is required for each output frequency, the Si544 uses one simple crystal and
a DSPLL IC-based approach to provide the desired output frequency. The
Si544 is factory-configurable for a wide variety of user specifications, includ-
ing startup frequency, I2C address, output format, and OE pin location/
polarity. Specific configurations are factory-programmed at time of shipment,
eliminating the long lead times associated with custom oscillators.
