The FarSync T2Ee PCIe card provides high performance 2 port low profile synchronous communications with multiple signalling modes for Linux and Windows systems.
The FarSync T2Ee card and software is designed to provide high performance hardware communications solutions for business, government and military requirements who require a low profile PCIe synchronous communications card with externally sourced line clocks or able to generate a wide range of clock speeds internally. The product includes a low level driver that allows access to the communications features available in the hardware.
The FarSync SDK provides a Developers Toolkit for the product.
The T2Ee is a PCIe communications card with two independently configurable sync serial ports. Sync operation supports transparent bitstream and bitsync (HDLC) of up to 10 Mbits/s per line with a total card bandwidth of 40 Mbits/s. The highly flexible universal network connector supports RS232, X.21, RS422, RS530, RS449, RS485 and V.35 network interfaces.
Line signalling modes: NRZ, Manchester encoding, FM0, FM1 and Conditioned Diphase (Differential Manchester) up to 10Mbits/s are handled by the FarSite customisable communications controller as well as soft selectable line termination resistance.
The transparent bitstream option available with the APIs is suitable for VoIP (as a subsystem), video and voice such as T-DMB (Digital Multimedia Broadcasting), DAB (Digital Audio Broadcasting) ETI (Ensemble Transport Interface – ETSI EN 300 799).
Supplied with standard and low profile PCIe I/O brackets, the photo above shows the FarSync T2Ee fitted with the low profile PCIe I/O bracket and the one below with the standard I/O bracket.
The drivers supplied with Windows and Linux allow large numbers of ports to be supported by the installation of multiple FarSync T2Ee cards in a Server. Typically 12 or more cards (24+ ports) can be supported; the card limit is only dependent on the resources available in the host Server and the total bandwidth of the PCIe bus.
The card comprises an AMD processor with no wait state SRAM. The whole memory space may be mapped via the PCIe interface to the PC/Server. The AMD processor contains a dual embedded HDLC / transparent controller with SDMA access (128 buffers per port) and a full range of timers. A FarSite communications controller (customisable).
The T2Ee supports two synchronous ports which can run to speeds of up to 10 Mbits/s full duplex internally clocked and 10 Mbits/s externally clocked. Total bandwidth supported by the card is 40 Mbits/s.
The multi function line drivers available on both ports support X.21 (V.11), V.35, RS232
(V.24), RS422, RS530, RS449, RS485, network interfaces, all soft configurable and ESD protected from static charges.
Internally Sourced Clocks
Internally generated clocks to drive a serial communications port can be derived from either an on-board 8.192MHz clock (25ppm) and can be set to hundreds of different frequencies between 100 baud and 10 Mbits/s, some of pre-programmed list is in the table below. Many other frequencies can be synthesized to order, contact us to discuss your requirements.
NRZ plus the self clocking (clock for the data is decoded from the incoming data line) line signalling modes Manchester Encoding, Conditioned Diphase (also known as Differential Manchester), FM0 and FM1 at speeds of up to 10 MBits/s. This means separate clock lines are not required, these line signalling modes are a soft configurable alternative to NRZ and a reliable way of handling long high speed cable runs.
Line termination is supported on all the balanced pair signals for X.21 (V.11), V.35, RS422, RS530 (EIA530), RS449 and RS485 operation. The line termination resistors may be soft selected to be selected on a port by port basis. The addition of line termination resistors helps improve signal quality on long high speed lines.
Terminal Timing is supported to enable system-wide clock synchronisation.
PCI Express Bus Specification
FarSync PCIe cards are suitable for systems with a PCIe bus, covering single and multi-processor systems. These cards are compliant with PCI Express Base specification revision 1.0a and above. The FarSync adapters are bus mastering, 1x (single lane) cards.
