DESCRIPTION
The Fujitsu MB15F72UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1300MHz and a
350MHz prescalers. A 64/65 or a 128/129 for the 1300MHz prescaler, and a 8/9 or a 16/17 for the 350MHz prescaler
can be selected for the prescaler that enables pulse swallow operation.
The latest BiCMOS process is used, as a result a supply current is typically 2.5mA typ. at 2.7V. The supply voltage
range is from 2.4V to 3.6V. A refined charge pump supplies well-balanced output current with 1.5mA and 6mA
selectable by serial data. The data format is same as the previous one MB15F02SL, MB15F72SP. Fast locking is
acheived for adopting the new circuit in the RF PLL section.
The new package(BCC20) decreases a mount area of MB15F72UL more than 30% comparing with the former
BCC16(for dual PLL).
MB15F72UL is ideally suited for wireless mobile communications, such as PDC.

Handling Precautions
(1) VccRF,VpRF,VccIF and VpIF must supply equal voltage.
Even if either RF-PLL or IF-PLL is not used, power must be supplied to both VccRF,VpRF,VccIF and VpIF to keep them
equal. It is recommended that the non-use PLL is controlled by power saving function.
(2) To protect against damage by electrostatic discharge, note the following handling precautions:
-Store and transport devices in conductive containers.
-Use properly grounded workstations, tools, and equipment.
-Turn off power before inserting or removing this device into or from a socket.
-Protect leads with conductive sheet, when transporting a board mounted device.

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.

Power saving mode
The intermittent mode control circuit reduces the PLL power consumption.
By setting the PS pin low, the device enters into the power saving mode, reducing the current consumption. See
the Electrical Characteristics chart for the specific value.
The phase detector output, Do, becomes high impedance.
For the single PLL, the lock detector, LD, remains high, indicating a locked condition.
For the dual PLL, the lock detector, LD, is as shown in the LD Output Logic table.
Setting the PS pin high, releases the power saving mode, and the device works normally.
The intermittent mode control circuit also ensures a smooth startup when the device returns to normal operation.
When the PLL is returned to normal operation, the phase comparator output signal is unpredictable. This is because
of the unknown relationship between the comparison frequency (fp) and the reference frequency (fr) which can
cause a major change in the comparator output, resulting in a VCO frequency jump and an increase in lockup time.
To prevent a major VCO frequency jump, the intermittent mode control circuit limits the magnitude of the error signal
from the phase detector when it returns to normal operation.

Note: When power (VCC) is first applied, the device must be in standby mode, PS=Low, for at least 1 s.

Pulses on Do
signals are output to prevent dead zone.
LD output becomes low when phase error is tWU or more.
LD output becomes high when phase error is tWL or less and continues to be so for three cycles or more.
tWU and tWL depend on OSCin input frequency as follows.
tWU > 2/fosc: i.e. tWU > 156.3ns when foscin = 12.8 MHz
tWL < 4/fosc: i.e. tWL < 312.5ns when foscin = 12.8 MHz
