TDA5051AT/C1,518 NXP

TDA5051A Home automation modem Rev. 5 13 January 2011 Product data sheet 1. General description The TDA5051A is a modem IC, specifically dedicated to ASK transmission by means of the home power supply network, at 600 baud or 1200 baud data rate. It operates from a single 5 V supply. 2. Features and benefits Full digital carrier generation and shaping Modulation/demodulation frequency set by clock adjustment, from microcontroller or on-chip oscillator High clock rate of 6-bit D/A (Digital to Analog) converter for rejection of aliasing components Fully integrated output power stage with overload protection Automatic Gain Control (AGC) at receiver input 8-bit A/D (Analog to Digital) converter 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 3. Applications Home appliance control (air conditioning, shutters, lighting, alarms and so on) Energy/heating control Amplitude Shift Keying (ASK) data transmission using the home power networkTDA5051A NXP Semiconductors Home automation modem 4.

DD(RX/TX)(tot) DD(PAMP) 2 Frequency range corresponding to the EN50065-1 band. However, the modem can operate at any lower oscillator frequency. 3 The minimum value can be improved by using an external amplifier see application diagrams Figure 19 and Figure 20. 5.
