描述
The 82EBP33831 Evaluation board for IEEE 1588 and Synchronous Ethernet (SyncE) allows the user to connect up to eight differential-ended, up to eight single-ended, and up to two Composite (AMI) reference inputs via SMA connectors. The inputs can operate at any frequency from 1PPS to 650MHz. Synchronization functions are provided by the IDT 82P33831 Digital PLL (DPLL) device, which integrates two low-jitter embedded clock synthesizers for Gigabit Ethernet and SONET/SDH PHYs and one ultra-low-jitter embedded clock synthesizers for 10G/40G Gigabit Ethernet.
As well as clock inputs and outputs the evaluation board supports control and monitoring of the IDT 82P33831 device from a Windows computer using Timing CommanderTM over a USB interface. The board can also be connected via external ribbon cable to control the IDT 82P33831 directly via I2C for 1588 applications, in which SW controls the DCO using frequency or phase offsets.
The IDT 82EBP33814 low jitter output clocks can be used to directly synchronize 1G/10G/40G Gigabit Ethernet and SONET/SDH devices by connecting the evaluation board’s SMA connectors to reference clock inputs on the system board.
