SiLabs launches ‘industry’s easiest to use’ clock cleaner IC
Silicon Laboratories has announced what it claims to be the industry's most frequency flexible timing solution. The Si5317 is designed for networking and telecommunications applications that require jitter attenuation for clock signals without clock multiplication.
The pin-controlled jitter cleaning clock IC is said to provide jitter filtering to remove unwanted noise and produces low jitter outputs for a range of applications.
The Si5317 is designed to remove unwanted noise on any clock frequency from 1 to 710MHz and produces two ultra-low jitter output clocks at the same frequency as the input. One Si5317-based design and layout supports jitter attenuation for any <710 MHz clock signal, enabling design reuse across multiple applications.
Pin settings configure the frequency range and PLL bandwidth, eliminating the need for firmware and serial programming required by traditional clock IC solutions. The clock cleaner delivers jitter performance of 0.29ps RMS, which enables a significant portion of the system jitter budget to be allocated to other devices.
Mike Petrowski, general manager of Silicon Labs' timing products, said: "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. The Si5317 simply drops into the clock path to provide jitter attenuation on clock signals up to 710MHz without requiring firmware configuration or BOM modifications to accommodate different frequencies."
Samples and production quantities of the Si5317 clock cleaner are available now.
