SL-514 Board
Overview
The DNx-SL-514 boards are high performance synchronous serial interface
boards.
DNA-SL-514, DNR-SL-514, and DNF-SL-514 boards are compatible with the
Cube, RACKtangle, and FLATRACK chassis respectively. These board versions
are electronically identical and differ only in mounting hardware. The DNA
version is designed to stack in a Cube chassis. The DNR/F versions are
designed to plug into the backplane of a RACK chassis.
SL-514 boards provide four independent channels, each having overvoltage
protection and opto-isolation.
1.2.1
Synchronous
Serial
Interface
The SL-514 offers four synchronous serial interface (SSI) channels. Each SSI
channel can be programmed independently, and each SSI channel offers a
master and slave port. Each master or slave port can be enabled independently.
1.2.2
Data Rates
Supported data rates are between 300 bps to 1.3 Mbps, programmed
independently per channel.
The master output clock is generated with 0.1% or better accuracy.
1.2.3
Data Word
Length
Supported data word lengths are programmable from 3 to 32 bits, programmed
independently per channel.
1.2.4
FIFO Storage
Master (receive) data storage is provided via a 2048 word x 32 bit FIFO. Slave
(transmit) data storage is provided via a 1024 word x 32 bit FIFO.
1.2.5
Software
Support
Software included with the DNx-SL-514 provides a comprehensive yet easy to
use API that supports all popular operating systems including Windows, Linux,
real-time operating systems such as QNX, RTX, VxWorks and more.
