Technical Features Of Matrox Helios Ea/Xa - Matrox Helios Series Installation And Hardware Reference

106 Appendix B: Technical information
• 8 Mbytes flash EEPROM.
Note that EEPROM is limited to 10000 write cycles.
❖
• Supports a x4 PCIe Host interface for Matrox Helios eCL; supports a 64-bit
66/100/133 MHz 3.3 V PCI-X (or a 64-bit 33/66 MHz 3.3 V or 5 V
conventional PCI) Host interface for Matrox Helios XCL.
• Integrated Watchdog circuitry
system failure.
• Supports an external rotary encoder with quadrature output.

Technical features of Matrox Helios eA/XA

• PCIe long board with a x4 PCIe connector, or a PCI/PCI-X long board with a
universal (3.3 V - 5 V) 64-bit board edge connector (5 V starting from revision 1
of the Matrox Helios PCB;
• Four independent acquisition paths. Each acquisition path has the following:
- Input from one of two software selectable sources. The source can be either AC
or DC coupled.
- Two low-pass filters: a 40 MHz filter and a 7.5 MHz filter.
- Variable gain amplifier and adjustable offset to set the black and white reference
levels.
- 10-bit A/D, with a sampling rate of up to 80 MHz.
• Four 4096 entry 8- or 16-bit programmable LUTs.
1. Starting from revision 1 of the Matrox Helios XCL PCB.
