Overview:	The HEGD2 uses 4 separate CS5101A 16 bit A/Ds, to provide multiple channels of A/D interfaced via the HETBASEIO or HEBASE104 to a 'C4x comport interface. The use of a common internal or external clock provides wide flexibility of sampling modes. Multiple modules can be interconnected to ensure simultaneous sampling. Choice of 4 simultaneously sampled channels at 100Ksps, or 8 channels at 50Ksps, where two groups of 4 channels are alternately sampled. Each group of 4 is sampled simultaneously, half of the sample clock apart from the other. For each enabled channel a sample clock edge will cause a 16-bit value to be sent in the bottom 16 bits of a comport word. The top 16 bits is used to identify the channels number. The Comport must be guaranteed to read the data at all times to prevent data loss. The inputs are separate connectors which input to the CS5101A via a protection buffer and filter. The Granddaughter module is 4.0" x 2.5" and is mounted above the TIM-40 with a board to board spacing of 0.2". The maximum height of components above the granddaughter module is 19mm, making the combination of motherboard plus HETBASEIO plus HEGD2 38mm.
