... The Fujitsu MB1519 is a 600MHz dual serial input PLL (Phase Locked) frequency synthesizer designed for cellular telephone and cordless telephone applications. The MB1519 has two PLL circuits on a single chip: one for transmit and the other for reception. Separate power supply pins are provided for the transmit and reception PLL circuits. Transmit PLL contains a low sensitivity charge pump for ease of modulation and reception PLL contains a high sensitivity charge pump for faster lock up time ...

... MB1519 FUNCTIONAL DESCRIPTIONS SERIAL DATA INPUT Serial data is input using three pins, Data pin, Clock pin, and LE pin. Programmable divider of transmit section and programmable divider of recep- tion section are controlled individually. Serial data of binary data is input into Data pin. On rising edge of clock shifts one bit of serial data into the shift register. When load enable signal is high, the data stored in the shift register is transferred to either the latch of transmit section or the latch of reception section depending upon the control bit data setting ...
