Abstract
Formatted serial synchronous character data is converted to serial asynchronous data, where the synchronous bit rate varies from the asynchronous intracharacter bit rate. The character data utilizes a start bit-stop bit format which enables the converter to insert stop bits occasionally in proportion to the bit rate difference, thus compensating for bit rate mismatch. The converter offers programmable character lengths of 7, 8, or 9 bits and a possible seven different asynchronous bit rates, each selected by three programmable selection inputs. In addition, the invention uses a total digital design architecture enabling gate array integrated circuit implementation.
