High when the device is in receive mode.
There are two sets of power signals, Vcc, Gnd and VccPLL, GndPLL. See 3.6
The SIG40 is designed to operate with one ceramic filter for transmission and reception. However, if
switching between two channels is desired, two ceramic filters are required. The minimum allowable
bandwidth of the ceramic filters is +/-70 kHz @ 3dB. Narrower bandwidth limits the maximal bit rate.
The SIG40 selectable frequencies are designed according to the market available ceramic filters.

* The 3.58MHz frequency can be operated at 19.2Kbps only.
The maximal cable length between extreme devices depends mainly on the AC impedance of loads
connected to that line and number of nodes. The DC cable length has less effect on communication.
The SIG40 needs at least 20mVpp for proper reception. Good communication should be achieved if
the transmitted signal can be seen on an oscilloscope at the receiving side within the line noise.
