AXM-D Series: Digital I/O Extension Modules for PMC & XMC FPGAs Description
AXM Series extension modules offer numerous I/O options for Acromag’s PMC modules with configurable FPGAs. These extension modules plug into the front mezzanine on Acromag’s PMC-LX/SX (Virtex®-4 FPGA), PMC-VLX/VSX/VFX (Virtex-5 FPGA) modules, and PMC-SLX (Spartan-6 FPGA) modules.
ACR5264 LVDS and RS-485 Differential I/O
This module provides 30 differential I/O channels. Data direction, either input or output, on each channel is independently controlled. Eight of the channels support programmable change-of-state interrupts. 16 LVDS and 14 RS-485 differential I/O channels.
AXM-D01 LVTTL I/O
This module provides 64 LVTTL I/O channels for straight though I/O. custom modules are available for optional pull-ups, pull-downs, JTAG, and fused power for front I/O use.
AXM-D02 RS-485 Differential I/O
This module provides 30 differential I/O channels. Data direction, either input or output, on each channel is independently controlled. Eight of the channels support programmable change-of-state interrupts. JTAG option.
AXM-D03 CMOS and RS-485 Differential I/O
This module provides 16 CMOS and 22 RS-485 differential I/O channels. Data direction, either input or output, on each channel is independently controlled. Eight of the channels support programmable change-of-state interrupts.
AXM-DX03 CMOS and RS-485 Differential I/O
Same as AXM-D03 above except 16 CMOS and 24 RS-485 differential I/O channels. Provides a replacement for legacy PMC-DX503/2003 FPGA modules when used with PMC/XMC-SLX.
AXM-D04 LVDS
This module provides 30 channels of low voltage differential signaling with independently configured direction. Interrupts are programmable on eight of the channels for any bit change of state or level. JTAG option.
