Hitek Systems
The Si558 network timing and clock synchronizer module is designed to pair with eSOM7 5G/Wireless development platform. Implements PTP/1588 and SYNCE based network synchronization and generates low phase noise transmit clock and JESD DevClk and SysRef reference signals required by most 5G ORAN and wireless/Satcom digitizer applications.

Features
- The Si5518 is designed as an optional add-on card to the eSOM5G/Wireless carriers, providing network synchronization and de-jittered clocks for wireless applications including 5G/O-RAN
- Small 2.2”x3.1” form factor module that plugs into the eSOM via 50-pin connector
- Based upon Skyworks Si5518 timing generator and synchronizer chip with high performance PTP/1588 support through Skyworks AccuTime or Clock Manager software respectively
- Module designed to support various operating modes:
- Network synchronizer for recovered or reference clocks
- Jitter attenuator for recovered clocks
- Full support for JESD 204B/C DevClkand SysRef generation for RF transceivers
- Provisioned with TCXO and OCXO for higher stability applications
- Connectors for external TOD, PPS/IRIG and reference clock inputs
