All versions are Not Recommended for New Designs.


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.
