6 Slot Backplane

A backplane which supports up to six expansion cards, meant to go into a 3U VME crate.

Features

  • Direction-controlled buffers for address and data bus
  • Mixer for audio from CPU board and expansion slots
  • Detection of installed peripheral cards via detect lines
  • An I2C bus switch to allow CPU board independent access to each slot’s sideband bus
  • Extremely low jitter clock distribution

It’s intended to be used in conjunction with the backplane management card for power, but the required +5V and +12V rails can also be provided through a 3.81mm pitch pluggable terminal block instead.
