SI5403B-A15255-GM

The Si5403B 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. Si5403B 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 Si5403B 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 Si5403B accepts 4/6 inputs clock ranging from 0.008 - 650 MHz differential and PPS/PP2S, 8kHZ to 250MHz for CMOS. Si5403B generates up to 18 clock outputs, each with output delay/skew adjust, ranging in frequency from PPS/PP2S up to 1288 MHz. Applications using AMD Xilinx ZYNQ Ultrascale+ ZCU102 or ZCU216 evaluation kits are supported with Skyworks 1588 Timing Demo Design which utilizes Si5403B and Skyworks AccuTime™ IEEE 1588 software. The Skyworks Xilinx Demonstration Platform solution Si5403-A-FMC-EVB is tailored to support these specific Xilinx platforms with a hardware and software IEEE 1588 timing solution including documentation and an ITU compliance reports. Si5403-A-FMC-EVB kit easily connects to the Xilinx eval boards and comes with the necessary hardware, cabling, software and jump-start guide to evaluate the Si5403 and AccuTime™ IEEE software solution on the Xilinx eval kit. The Skyworks Si5403 + AccuTime IEEE 1588 timing solution also supports AMD Xilinx ZYNQ RFSoC DFE. Applications that split the network synchronization clocking function from the RF data converter clocking function (split board) should use the Si5403B along with the Si5510A wireless JA to clock the RF data converters. Customers should consider using Si5518B for a single chip IEEE 1588 clock solution that combines the network synchronization function with the wireless JA function in a single device. The Skyworks solution meets the requirements specified by ITU-T G.8262 EEC Options 1 & 2 and ITU-T G.8262.1 and 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). Customers should contact Xilinx for the appropriate Xilinx eval kit and Skyworks for the Si5403-A-FMC-EVB kit. This device is supported by Skyworks AccuTime™ IEEE 1588 software.
