1x22
The 73M1x22 is a third generation silicon Direct Access Arrangement (DAA) that offers state of the art performance at a competitive price. Supporting Analog Front End (AFE) and DAA functionality, the 73M1x22 with a single BOM provides programmable compliance for global PTT homologation needs. The 73M1822 is the world’s first single package silicon DAA offering all the functionality of the 73M1x22 family in a small 8mm x 8mm QFN package that supports normal and extreme environments.Features
Full Analog Front End (AFE) and DAA (Direct Access Arrangement) for voice-band modem applications- Integrated functionality supports the connection of voice-band modems and devices to the PSTN
- Single package small form factor provides up to 4.5kV isolation
- Chip set allows for support for over 4.5kV isolation (recommended for 6kV applications)
- Global DAA compliance with FCC, TBR-21, JATE and other PTT standards with one BOM
- Choice of PSTN line termination and impedance matching circuits to meet global needs
- Programmable PSTN line current control to match different country homologation requirements
- Best in class EMI and noise performance
- Improved loop length performance by providing power to line side device over the isolation barrier
