PLL Frequency Synthesizer
MB15F73UL
■ DESCRIPTION
The Fujitsu MB15F73UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2250 MHz and
a 600 MHz prescalers. A 64/65 or a 128/129 for the 2250 MHz prescaler, and a 8/9 or a 16/17 for the 600 MHz
prescaler can be selected for the prescaler that enables pulse swallow operation.
The BiCMOS process is used, as a result a supply current is typically 3.2 mA at 2.7 V. The supply voltage range
is from 2.4 V to 3.6 V. A refined charge pump supplies well-balanced output current with 1.5 mA and 6 mA
selectable by serial date. The data format is the same as the previous one MB15F03SL, MB15F73SP. Fast locking
is achieved for adopting the new circuit.
The new package (BCC20) decreases a mount area of MB15F73UL more than 30% comparing with the former
BCC16 (for dual PLL) .
MB15F73UL is ideally suited for wireless mobile communications, such as GSM and PCS.

Power supply voltage
Note : • 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 VCCRF, VpRF, VCCIF and VpIF to keep
them equal.
It is recommended that the non-use PLL is controlled by power saving function.
• Although this device contains an anti-static element to prevent electrostatic breakdown and the circuitry
has been improved in electrostatic protection, observe the following precautions when handling the device.
• When storing and transporting the device, put it in a conductive case.
• Before handling the device, confirm the (jigs and) tools to be used have been uncharged (grounded) as
well as yourself. Use a conductive sheet on working bench.
• Before fitting the device into or removing it from the socket, turn the power supply off.
• When handling (such as transporting) the device mounted board, protect the leads with a conductive
sheet.
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.

fVCO : Output frequency of external voltage controlled oscillator (VCO)
P : Preset divide ratio of dual modulus prescaler (8 or 16 for IF-PLL, 64or 128 for RF-PLL)
N : Preset divide ratio of binary 11-bit programmable counter (3 to 2,047)
A : Preset divide ratio of binary 7-bit swallow counter (0 ≤ A ≤ 127, A < N)
fOSC : Reference oscillation frequency (OSCIN input frequency)
R : Preset divide ratio of binary 14-bit programmable reference counter (3 to 16,383)
2. Serial Data Input
The serial data is entered using three pins, Data pin, Clock pin, and LE pin. Programmable dividers of IF/RFPLL sections, programmable reference dividers of IF/RF-PLL sections are controlled individually.
The serial data of binary data is entered through Data pin.
On rising edge of Clock, one bit of the 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 latches depending upon the control bit
data setting.

3. Power Saving Mode (Intermittent Mode Control Circuit)
Status
PS pin
Normal mode
H
Power saving mode
L
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 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 comparaor 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.
Notes : • When power (VCC) is first applied, the device must be in standby mode, PS = Low, for at least 1 µs.
• PS pin must be set “L” at Power-ON.

4. Serial Data Data Input Timing
Divide ratio is performed through a serial interface using the Data pin, Clock pin, and LE pin.
Setting data is read into the shift register at the rise of the Clock signal, and transferred to a latch at the rise of
the LE signal. The following diagram shows the data input timing.

Notes : • Phase error detection range = −2π to +2π
• Pulses on DoIF/RF signals during locking state 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 : e.g. tWU ≥ 156.3 ns when fosc = 12.8 MHz
tWU ≤ 4/fosc : e.g. tWL ≤ 312.5 ns when fosc = 12.8 MHz

■ USAGE PRECAUTIONS
(1) VCCRF, VpRF, VCCIF and VpIF must be equal voltage.
Even if either RF-PLL or IF-PLL is not used, power must be supplied to 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
