The 73M1922 MicroDAA Chipset Demo Board integrates silicon Data Access Arrangement (DAA) function along with Analog Front End functions chipsets for worldwide compliance.
The 73M1922 MicroDAA chipset consists of a 73M1902 and a 73M1912. The 73M1902 is the Host Interface Chip (HIC) providing a host microprocessor or DSP interface by a synchronous serial port (Modem Analog Front End (MAFE)) and the 73M1912 is the Line Interface Chip (LIC) to connect to a telephone line.
The 73M1922 chipset is packaged in two 20-pin TSSOP or two 32-pin QFN packages for a very small physical dimension and offers low cost global DAA design.
