Description
AI
The LMK05318B-Q1 is high-performance network synchronizer clock device that provides jitter cleaning, clock generation, advanced clock monitoring, and superior hitless switching performance to meet the stringent timing requirements of communications infrastructure and industrial applications. The ultra-low jitter and high power supply noise rejection (PSNR) of the device can reduce bit error rates (BER) in high-speed serial links.
