AXM-DIFF30
AXM FGA INTERFACE 30 DIFFERENTIAL RS-485 Channels w/CONTROL & TERMINATION
The AXM-DIFF30 is a high-performance AXM interface board designed to manage 30 differential signal lines, with channel-specific direction control for enhanced flexibility. It supports 120 Ohm terminators and achieves a maximum data rate of 20 Mbps, ensuring reliable and high-speed signal transmission. The board is engineered to withstand ±25kV protection against damage or latch-up, and its high input impedance supports up to 256 nodes, making it ideal for complex systems. Additionally, a guaranteed failsafe receiver ensures stable operation across the full common-mode range. The AXM-DIFF30 is a drop-in replacement for the AXM-D02-JTAG, offering full compatibility with existing systems. It complies with TIA/EIA-485-A specifications and connects seamlessly via a 68-pin SCSI front panel connector, providing a robust and reliable solution for high-speed differential signaling applications.
