Serial Data Input
The serial data is entered using three pins, Data pin, Clock pin, and LE pin. Programmable dividers of IF/RF-
PLL sections, programmable reference dividers of IF/RF-PLL sections are controlled individually.
The serial data of binary data is entered through Data pin.
On rising edge of Clock, one bit of the serial data is transferred into the shift register. On a rising edge of load
enable signal, the data stored in the shift register is transferred to one of latches depending upon the control bit
data setting.
