HCS6320 Functional Blocks

The HCS6320 consists of four main functional blocks:

•MUX: Four parallel multiplexers, each of which can combine up to two encrypted transport streams into a single 38 Mbps transport stream. The transport streams from the transcoder cards are supplied to the HCS6320 through the internal backplane circuit board of the card frame.

•MOD: Four parallel 256-QAM modulators that take the MUX output streams and produce four modulated outputs.

•Upconverter: This block takes the modulated output streams from the MOD block and places them on up to four contiguous cable RF channels. The output of this block is a combined RF signal four channels wide.

•Controller: Provides the PC interface for HCS6320 setup and configuration.

HCS6320 default settings assign the inputs of each channel MUX to specific slots in the CodePlus card frame, where the RF start channel is assigned to card frame Slots 1 & 2, the second channel is assigned to card frame Slots 4 & 5, etc.
