SLAVE MODE
If the SCLK pin is externally pulled down to ground by a <4.7K
resistor when RST is active, the
79M1903C device goes in the slave mode. In this mode of operation the serial clock (SCLK) and
FS are
inputs to 79M1903C provided by the Master device. The serial clock input must be connected to OSCIN
pin while SCLK pin of 73M1903C is unconnected, except for the resistor connected to ground (see
Figures 1 and 2). The 73M1903C PLL must be programmed to multiply the serial clock frequency by an
appropriate factor in order to obtain Fsys. Therefore the serial clock has to be continuous and without low
frequency jitter (the high frequency jitter is rejected by the 79M1903C PLL). The SckMode pin is not used
since the Master device provides
FS and SCLK.

Figure 2: 73M1903C Daisy chaining for master/slave mode and slave modes
In order to daisy chain two or more 73M1903C devices, the master must be programmed into HC mode,
then set FSBDEn (Bit 3 in register 06), and then set CkoutEn bit (Bit 3 in register 01) to allow the FSBD to
come through. The first frame after enabling FSBD must be Data. For the two daisy chained devices,
