Si5403P

NetSync™ Network Synchronizer Clock for 5G/SyncE/IEEE 1588 applications


The Si5403P NetSync™ Network Synchronizer Clock utilizes 5th generation DSPLL technology and is a feature rich device capable of meeting all the requirements of Synchronous Ethernet (SyncE)-compliant wander filtering and software adjustment of output frequency and phase for IEEE 1588 applications. Si5403P offers ultra-low jitter output clocks eliminating the need for a follow-on jitter attenuator device. It’s combination of unique architecture and features helps enable lower overall system cost, PCB footprint and power consumption - all required for use in today’s high-performance networks.

The Si5403P provides any-frequency clock generation and jitter attenuation for applications requiring the highest level of jitter performance. The device has enhanced hitless switching to minimize output phase transients when switching between two different inputs at the same frequency. No external loop filter components are required and the DSPLL bandwidth is digitally programmable to values as low as 0.001 Hz. With phase jitter as low as 51 fs RMS, the Si5403P accepts 4/6 inputs clock ranging from 0.008 - 650 MHz differential and PPS/PP2S, 8kHZ to 250MHz for CMOS. Si5403P generates up to 18 clock outputs, each with output delay/skew adjust, ranging in frequency from PPS/PP2S up to 1288 MHz.

The Si5403P meets all of the requirements specified by ITU-T G.8262 EEC Options 1 & 2 and ITU-T G.8262.1. When used with external IEEE 1588 stack and servo loop software the Si5403P meets all the requirements of ITU-T G.8273.2 (T-TSC, T-BC), ITU-T G.8273.4 (T-BC-P, T-BC-A, T-TSC-P, T-TSC-A) and G.8273.1 (T-GM). Si5403P does not support AccuTime™ 1588 software and is currently for special use only. Customers interested in using Skyworks AccuTime™ IEEE 1588 software should use Si5403B.
