Overview:	The HEGD5 uses 4 separate Burr Brown PCM55HP 16-bit D/As, providing multiple channels of D/A interfaced via the HETBASEIO or HETBASE104 to a 'C4x comport interface. A common internal or external clock provides flexible sampling modes. Multiple modules can be interconnected to ensure simultaneous sampling. The Comport sends the HETBASEIO or HEBASE104, words containing one sample, along with a channel identifier for that data. After each sample clock, the HEGD5 will read samples from the HETBASEIO or HEBASE104 and latch them ready for the channels identified in the data. The next sample clock will apply the new values to the D/As. In this way some or all of the channels can be updated, and a channel that has not received an update for this sample clock will continue to use its previous sample value, thus preventing unpredictable output behavior. The outputs are separate SMB connectors which are connected to the D/As 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 spacing of 0.2". The maximum height of components above the granddaughter module is 25mm, making the combination of Motherboard plus HETBASEIO or HETBASE104 plus HEGD5 43mm.
