TDA5051
Overview
- Full digital carrier generation and shaping
- Modulation/demodulation frequency set by clock adjustment, from microcontroller or on-chip oscillator
- High clock rate of 6 bits D/A (Digital-to-Analog) converter for rejection of aliasing components
- Fully integrated output power stage with overload protection
- Automatic gain control at receiver input
- 8-bit A/D and narrow digital filtering
- Digital demodulation delivering baseband data
- Easy compliance with EN50065-1 with simple coupling network
- Few external components for low cost applications
- SO16 plastic package.
