NetSync™ Low Phase Noise Jitter Attenuating Clock For 5G/eCPRI/SyncE/IEEE: Si5518B
The Si5518B NetSync Network Synchronizer Clock combines the functions of a SyncE/IEEE 1588 PTP network synchronizer clock with a low phase noise 5G/eCPRI wireless jitter attenuator into a single IC device.
The Si5518B is optimized for 5G wireless applications which demand the highest level of integration and phase noise performance with low power consumption that reduces the total solution cost. This highly integrated digital solution eliminates external loop filter components and has high immunity to external board disturbances such as power supply noise.
The DSPLL bandwidth is digitally programmable to values as low as 0.001 Hz. With phase jitter as low as 47 fs RMS, the Si5518B accepts 4/6 inputs clock ranging from 0.008 - 1000 MHz differential and PPS/PP2S, 8kHz to 250MHz for CMOS. Si5518B generates up to 18 clock outputs that are configurable in any combination of DCLK, SYSREF or other system clocks. Each output supports delay/skew adjust and frequencies ranging from PPS/PP2S up to 3200 MHz. For additional product specifications and information, click here.
