FPGA/ASIC clock generation

Description

V_DD

The Si512/513 dual frequency XO utilizes Silicon Laboratories' advanced

PLL technology to provide any frequency from 100 kHz to 250 MHz. Unlike a

traditional XO where a different crystal is required for each output frequency,

the Si512/513 uses one fixed crystal and Silicon Labs’ proprietary any-

frequency synthesizer to generate any frequency across this range. This IC-

based approach allows the crystal resonator to provide enhanced reliability,

improved mechanical robustness, and excellent stability. In addition, this

solution provides superior supply noise rejection, simplifying low jitter clock

generation in noisy environments. The Si512/513 is factory-configurable for a

wide variety of user specifications, including frequency, supply voltage,

output format, output enable polarity, and stability. Specific configurations are

factory-programmed at time of shipment, eliminating long lead times and

non-recurring engineering charges associated with custom frequency

oscillators.
