The LMK5B12204 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.

The device can generate output clocks with 50-fs RMS jitter using TI’s proprietary Bulk Acoustic Wave (BAW) VCO technology, independent of the jitter and frequency of the XO and reference inputs.
