SyncLink® PCI Express Adapter Solutions

SyncLink® GT4e PCIe Adapters

SyncLink PCI Adapters
Multiport High-Speed PCIe Adapter.

The SyncLink PCI Express(PCIe) adapters feature bus master control for sustained 10Mbps synchronous communications simultaneously on all four ports. The SyncLink GT4e supports asynchronous connections up to 8Mbps. The 1x bus connector supports the latest workstation, stand-a-lone server, rack mount server or ruggedize system requiring synchronous or asynchronous connections. The number of adapters one can place in a single system is only limited by the number of slots available in the computer.

The SyncLink family of synchronous adapters utilizes the MicroGate FPGA Serial Controller. Beyond providing seamless integration between the hardware and software drivers, MicroGate is able to offer customized serial controller interfaces for users needing additional control over the serial links. There is no need for custom hardware but rather quick modifications to the FPGA programming.

Other features include:

  • SDLC, HDLC, BISYNC, MONOSYNC, ISOCHRONOUS, ASYNC, RAW bit-synchronous protocols
  • Selectable hardware CRC: CRC-16, CRC-32, None
  • DPLL clock recovery (8x/16x)
  • Separate, selectable transmit and receive data clock inputs
  • Baud Rate Generator for sourcing data clocks
  • Variety of transmit preamble and idle patterns
  • Encoding: NRZ,NRZB,NRZ-L,NRZI,NRZ-M,NRZ-S,BIPHASE,FM0,FM1,Manchester,differential biphase level
  • Full control and monitoring of DTR,RTS,DSR,DCD,CTS,RI
  • Time Division Multiplexing (TDM) compatible with TDM mode of McASP
  • Optional termination for differential inputs
  • Optional fail safe biasing for differential inputs
  • General Purpose I/O (GPIO) signal access
  • Loopback mode for diagnostics

Full-Featured Software Development Kit.

Supporting both 32-bit and 64-bit versions of Windows and Linux (x86), the MicroGate Serial API gives developers direct access to the SyncLink adapter and serial link for total control of HDLC/SDLC, BISYNC, MONOSYNC, ISOCHRONOUS, ASYNC and RAW synchronous bit streams. These protocols are used to build applications for networking, X.25, IBM SDLC (SNA), satellite, radio and other serial communications.

Additional Support.

The SyncLink drivers are part of the base Linux kernel, providing direct support with Linux networking options.

Industry standard server support for SNA/SDLC connections include Microsoft's Host Integration Server, IBM's Personal Communications Manager (PCOMM) and Communications Server for Windows (CS\Windows). More details about these solutions can be found in the "Solutions by Software" section of the MicroGate website.

20Mbps versions of the adapters and Extended-Temperature range models are also available.
