Function
PCM-interface: Transmit control output A, is active if
data is transmitted via DXA, active low, open drain
Reset input - forces the device to default mode,
active low
Master clock input, 1536, 2048, 4096 or 8192 kHz,
synchronous to FSC, must be available if the
SICOFI-4- C is used
write data, active low
to device, the maximum clock rate is 8192 kHz
determines the data rate
determines the data rate, DOUT is high ‘Z’ if no data
is transmitted from the SICOFI-4- C
Chopper Clock output, provides a programmable
(2 … 28 ms) output signal (synchronous to MCLK)
Chopper Clock output, provides a 256, or 512 or
16384 kHz signal, is synchronous to MCLK
Interrupt output pin for channel 1 and 2, active high
Interrupt output pin for channel 3 and 4, active high
-Controller interface: chip select enable to read or
-Controller interface: data clock, shifts data from or
-Controller interface: control data input pin, DCLK
-Controller interface: control data output pin, DCLK
