DESCRIPTION
The Fujitsu MB15F04 is a serial input Phase Locked Loop (PLL) frequency synthesizer with two 2.0GHz prescalers. A 64/65 or a 128/129 for both 2.0GHz prescalers can be selected that enables pulse swallow operation. The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 11.0mA typ. at a supply voltage of 3.0V. Furthermore, a super charger circuit is included to provide a fast tuning as well as low noise performance. As a result of this, MB15F04 is ideally suitable for digital mobile communications. s

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

POWER SAVING MODE (Intermittent Mode Control Circuit)
Setting a PSTX(RX) pin to Low, TX-PLL (RX-PLL) enters into power saving mode resultant current consumption can be limited to 0.1 A (typ.). Setting PS pin to High, power saving mode is released so that the device works normally. In addition, the intermittent operation control circuit is included which helps smooth start up from stand by mode. In general, the power consumption can be saved by the intermittent operation that powering down or waking up the synthesizer. Such case, if the PLL is powered up uncontrolled, the resulting phase comparator output signal is unpredictable due to an undefined phase relation between reference frequency (fr) and comparison frequency (fp) and may in the worst case take longer time for lock up of the loop. To prevent this, the intermittent operation control circuit enforces a limited error signal output of the phase detector during power up. Thus keeping the loop locked. PS pin must be set "L" at Power-ON. Allow 1 s after frequency stabilization on power-up for exiting the power saving mode (PS: L to H) Serial data can be entered during the power saving mode. During the power saving mode, the corresponding section except for indispensable circuit for the power saving function stops working, then current consumption is reduced to 10A per one PLL section. At that time, the Do and LD become the same state as when a loop is locking. That is, the Do becomes high impedance. A VCO control voltage is naturally kept at the locking voltage which defined by a LPF's time constant. As a result of this, VCO's frequency is kept at the locking frequency.

ANALOG SWITCH (BSCTX Pin)
The analog switch is set on or off by the BSCTX input. When the switch is on, the output of the charge pump (DoTX) is output from the BSTX pin. (The pin goes to high impedance when the switch is off.) Analog switch ON OFF BSCTX H L
As in the example shown in the figure below, placing the analog switch midway through the LPF (LPF1 + LPF2) allows the LPF time constant to be reduced during PLL channel switching so as to speed up the lock up time.
