Reference oscillation frequency
Preset divide ratio of binary 14-bit programmable reference counter (3 to 16,383)
Serial Data Input
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.
Serial data of binary data is entered through Data pin.
On a rising edge of clock, one bit of 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 latch of them depending upon the control bit data
setting.
