Function

µ-Controller interface: control data input pin, DCLK

determines the data rate

µ-Controller interface: control data output pin, DCLK

determines the data rate, DOUT is high ‘Z’ if no data

is transmitted from the SICOFI2/4-TE

Ring generator output, provides a programmable

(2 … 28 ms) output signal (synchronous to DCL)

Chopper Clock output, provides a 256, or 512 or

16384 kHz signal, is synchronous to DCL

Interrupt output pin for channel 1 and 2, active high

+ 5 V Analog supply voltage 1)

Ground analog for unused analog I/O pins

None usable input, tie directly to GNDD

None usable input/output, tie via a pull-down-resistor

to GNDD.

None usable, leave unconnected

+ 5 V Analog supply voltage for channel 3 and 41)

Interrupt output pin for channel 3 and 4, active high
