The Fujitsu MB1502, utilizing BI-CMOS technology, is a single chip serial input PLL
synthesizer with pulse-swallow function. The MB1502 contains a 1.1GHz two
modulus prescaler that can select of either 64/65 or 128/129 divide ratio, control
signal generator, 16-bit shift register, 15-bit latch, programmable reference divider
(binary 14-bit programmable reference counter), 1-bit switch counter, phase
comparator with phase conversion function, charge pump, crystal oscillator, 19-bit
shift register, 18-bit latch, programmable divider (binary 7-bit swallow counter and
binary 11-bit programmable counter) and analog switch to speed up lock up time.
It operates supply voltage of 5V typ. and achieves very low supply current of 8mA typ.
realized through the use of Fujitsu Advanced Process Technology.

... MB1502 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 18-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.
