Serial data input is input using Data pin, Clock pin and LE pin, The 15-bit programmable reference divider and 18-bit programmable divider are controlled respectively.

On rising edge of the clock shifts one bit of the data into the internal shift registers.

When load enable (LE) is high level (or open), data stored in shift resisters is transferred to 15-bit latch or 18-bit latch depending upon the control bit level.

Control data "H" ; Data is transferred into 15-bit latch.

Control data "L" ; Data is transferred into 18-bit latch.
