TIP115

5 Channel SSI Interface with ‘Listen Only’ Mode

Application Information

The TIP115 is an IndustryPack

 compatible module for

motion control applications.

The TIP115 offers five independent channels. Each of

these channels can be operated as a standard SSI

interface controller or in a ‘Listen only’ mode.

The standard SSI interface controller outputs a clock burst

to the absolute encoder and receives the returned

positional data. The SSI interface controller operates with

a programmable clock rate from 1µs to 15µs and

programmable data word length from 1 bit to 32 bit.

In ‘Listen only’ mode the channel listens to an existing SSI

interface to observe its data transfer. It takes both the SSI

clock and data as inputs. In ‘Listen only’ mode the channel

also has a programmable data word length from 1 bit to 32

bit; the SSI clock rate of the observed SSI interface can be

in the range of 1µs to 15µs.

In both modes the data word can be encoded in Binary- or

in Gray-Code and with odd, even or no parity.

The data inputs are galvanically isolated by high speed

optocouplers. The level of the input and output signals is

RS422.

Software support (TIP115-SW-xx) is available for different

operating systems.
