Configuring the ICS307
The ICS307 can be programmed to set the output functions and frequencies. The three data bytes are
written to the DATA pin, in this order:
V8 V7 V6 V5 V4 V3 V2 V1
V0 R6 R5 R4 R3 R2 R1 R0
C1 is loaded into the port first and R0 last.
Programming Example
To generate 66.66 MHz from a 14.31818 MHz input, the RDW should be 59, the VDW should be 276,
and the Output Divide is 2. Selecting the minimum internal load capacitance, CMOS duty cycle, and CLK2
to be OFF means that the following three bytes are sent to the ICS307:
00110001
Byte 1
10001010
Byte 2
00111011
Byte 3
As shown in Figure 2, after these 24 bits are clocked into the ICS307, taking STROBE high will send this data
to the internal latch, and the CLK output will lock within 10 ms.
NOTE: If STROBE is in the high state and SCLK is pulsed, DATA is clocked directly to the internal latch
and the output conditions will change accordingly. Although this will not damage the ICS307, it is
recommended that STROBE be kept low while DATA is being clocked into the ICS307 in order to avoid
unintended changes on the output clocks.
