The devices' low additive jitter allows system designers to distribute multiple copies of a clean clock
(while maintaining clock integrity) and eliminates the need for additional jitter cleaning components.
The SLC offers two clean clocks
in a single compact package to achieve low jitter measurements down to -170 dBc/Hz at 10 MHz and 40 fs (femtoseconds) RMS on a 155 MHz clock for example.
When fed with a clean input reference clock, a DPLL can compensate for those short-term fluctuations and provide clean clocks
at its output.
The Si5317 is the industry's most versatile and user-friendly jitter attenuating clock cleaner, providing an ultra-low jitter solution for high-performance and cost-sensitive access and networking applications that require exceptionally clean clocks
," said Mike Petrowski, general manager of Silicon Labs' timing products.
The LMK04000 devices provide clean clocks
to analog-to-digital converters (ADC), digital-to-analog converters (DAC) and other high-performance components used in wireless infrastructure, test and measurement, and medical ultrasound and imaging equipment.
