TDA5051A

Home automation modem

[1] The value of the total transmission mode current is the sum of I

DD(RX/TX)(tot)

+ I

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.
