The MVME6100 series is the first VMEbus single-board computer (SBC) designed with the Tundra Tsi148™ VMEbus interface chip offering 2eSST VMEbus performance. The 2eSST (two edge source synchronous transfer) protocol causes the VMEbus to run at a practical bandwidth of 320MB/s in most cases. The 2eSST protocol has existed for some time (the draft standard for trial use was published in 1999 and released as an ANSI standard in 2003), but until now, 2eSST boards would not work in a standard VMEbus backplane because the existing VMEbus transceivers could not support the required VMEbus 2eSST signaling speeds. Texas Instruments has developed new VMEbus transceivers that support the VMEbus signal switching speeds required by the 2eSST protocol. The combination of the new Texas Instruments VMEbus transceivers and the Tsi148 VMEbus legacy protocol support allows customers to integrate the MVME6100 series into their existing infrastructure providing backward compatibility and thereby preserving their investment in existing VMEbus boards, backplanes, chassis and software.
