Description
Embedded Characteristics
The Software Modem Device (SMD) is a block for communication via a modem's Digital Isolation
Barrier (DIB) with a complementary Line Side Device (HLSD).
SMD and HLSD are two parts of the "Transformer only" solution. The transformer is the only
component connecting SMD and HLSD. The transformer is used for power, clock and data
transfers. Power and clock are supplied by the SMD and consumed by the HLSD. The data flow
is bidirectional. The data transfer is based on pulse width modulation for transmission from the
SMD to the HLSD, and for receiving from the HLSD.
There are two channels embedded into the protocol of the DIB link:
Each channel is bidirectional.
The data channel is used to transfer digitized signal samples at a constant rate of 16 bits at
16 kHz.
The control channel is used to communicate with control registers of the HLSD at a maximum
rate of 8 bits at 16 kHz.
The SMD performs all protocol-related data conversion for transmission and received data inter-
pretation in both data and control channels of the link.
The SMD incorporates both RX and TX FIFOs, available through the DMAC interface. Each
FIFO is able to hold eight 32-bit words (equivalent to 16 modem data samples).
