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 .
