Product Summary
The AM7911PC is a high performance FSK modem chip. It includes most of the building blocks required for a complete communication system. The AM7911PC features include: analog-to-digital and digital-to-analog converters, internal crystal oscillator, and the essential RS-232/CCITT V.24 terminal control signals with TTL levels. A DAA or acoustic cuopler must be supplied externally to provide the phone line interface. The AM7911PC has the same basic structure as shown in the simplified blocj diagram.
