Principle functionality of the SSI interface

Data communication of the SSI interface is based on differential transmission as used for
RS 422 interfaces. Transmission of the position value, beginning with the MSB (most
significant bit), is thus synchronised with a clock cycle (CLOCK) specified by the control.

In the quiescent state both the clock line as well as the data line are at HIGH level. At the
first HIGH-LOW edge (point

1

in figure 10.1) the data in the internal register are stored. Thus

it is ensured that the data cannot change during serial transmission.

When the next clock signal change from LOW to HIGH level (point

2

in figure 10.1) occurs

transmission of the position value begins with the most significant bit (MSB). With each
successive change of the clock signal from LOW to HIGH level the next least-significant bit
is transmitted on the data line. After the least significant bit (LSB) has been output, the clock
signal switches from LOW to HIGH for one last time and the data line switches to LOW level
(end of transmission).

A monoflop retriggered by the clock signal determines the time span before the SSI interface
can be called for the next transmission. This results in the minimum pause time between
two successive clock cycles. If time tm = 20 μs has elapsed, the data line is returned to the
quiescent level (HIGH) (point

3

in figure 10.1). This signals completed data communication

and that the device is again ready for transmission.

Notice!

If the off-cycle of data transmission is interrupted for longer than t

m

= 20 μs, the next cycle

will begin with a completely new transmission cycle with a newly calculated value.

If a new transmission cycle is started before time t

m

has elapsed, the previous value is output

again.

Attention!

The SSI interface can only represent positive distance values. If negative output values
are ascertained due to the offset or count direction, a zero value is output at the SSI
interface! In the event of a number overflow, all data bits are set to "1".
