The syn1588®Clock_M IP core offers the full syn1588® technology with a suiteable number of trigger and IO events supported. The syn1588®Clock_M IP core is suited for direct integration of a MAC and/or a processor on a single chip (SOC/SOPC design). A standard AHB interface (slave) is available for communication to the host processor executing the PTP stack.
Typical application example is the syn1588® PCI NIC. A standard PCI Ethernet network interface card is made up of a single FPGA that includes the syn1588®Clock_M IP core as well as the Eternet MAC and the PCI interface.
Description
Oregano Systems offers a full range of clock cores, which are compatible to the IEEE1588 Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems. The IP cores differ in footprint, number of I/Os, interface, and supported features.
Features
- fully synchronous to the system clock
- all registers of the core operate with the rising clock edge
- well commented, well structured VHDL cource code
- medium footprint and medium I/O count
- advanced high-performace bus (AHB) slave interface for clock control
- media independent interface (MII or GMII) for sync message detection
- 10/100/1000 Mbit/s Ethernet interface supported
- 10 Gbit/s Ethernet interface (XGMII) available upon request
- two event inputs, two trigger outputs, two period outputs, one 1 pulse per second (PPS) output
- generation of interrupt upon several events
- pipelined adder based clock for best synchronization results
- seperate receive and transmit timestamp FIFOs
- clock time format compatible to the IEEE1588 standard
- suited for FPGA as well as ASIC implementations

Ressources & Performance
The following table gives a rough overview of the area consumption of the syn1588®Clock_M IP core as well as the achieved maximum frequency for selected target technologies.
Note that the actual implementation figures depends on the selected target technology or FPGA device (family, package, speed grade) as well as the constraints (minimum area or maximum frequency) used for implementing the core.

Licences
Like for all Oregano Systems' IP cores there are two ways to license the syn1588®Clock_M IP core.
- technology netlist license for a selected FPGA technology or device
- source code license
When ordering the technology netlist license a gate level netlist for the selected target technology is delivered. The IP core is pre-configured during the netlist generation process and cannot be changed by the user.
When ordering the source code license, the complete VHDL source code of the syn1588®Clock_M core is delivered. Thus the customer may change the IP core as required for the application. The VHDL code is fully synthesizeable and requires no special constraints.
There is a complete verification setup for both licensing schemes available that enables system simulation and standard compliance tests.
