ATSC 8-VSB modulator

Product code: CMS0033

 
The CMS0033 ATSC 8-VSB modulator with integrated Channel Coder has been designed specifically to implement the 8-VSB requirements of the ATSC Digital Television Standard (A/53).
The core provides all the necessary processing for 8VSB modulation of a single transport stream. Supported output formats include baseband I/Q and IF.
Every effort has been made to keep the size of the block to an absolute minimum in order to target the low-cost FPGA families, however this has not been at the expense of functionality.
