... MB1507 FUNCTIONAL DESCRIPTIONS SERIAL DATA INPUT Serial data input is achieved by three inputs, such as Data pin, Clock pin and LE pin. Serial data input controls 15–bit programmable reference divider and 19–bit programmable divider, respectively. Binary serial data is input to Data pin. On rising edge of clock shifts one bit of serial data into the internal shift registers and when load enable pin is high level or open, stored data is transferred into latch depending upon the control bit. Control data ” ...
