Fractional-N
PLL Frequency Synthesizer
MB15F83UL
■ DESCRIPTION
The Fujitsu MB15F83UL is Fractional-N Phase Locked Loop (PLL) frequency synthesizer with fast lock up function.
The Fractional-N PLL operating up to 2000 MHz and the integer PLL operating up to 600 MHz are integrated on
one chip.
The MB15F83UL is used, as charge pump which is well-balanced output current with 1.5 mA and 6 mA selectable
by serial data, direct power save control and digital lock detector. In addition, the MB15F83UL adopts a new
architecture to achieve fast lock.
The new package (Thin Bump Chip Carrier20) decreases a mount area of MB15F83UL more than 30% comparing
with the former B.C.C.16 (for dual PLL, MB15F03SL) .
The MB15F83UL is ideally suited for wireless mobile communications, such as GSM.
■ FEATURES
• High frequency operation
: RF synthesizer : 2000 MHz Max.
: IF synthesizer : 600 MHz Max.
• Low power supply voltage
: VCC = 2.7 V to 3.6 V
• Ultra Low power supply current : ICC = 5.8 mA Typ. (VCC = Vp = 3.0 V, Ta = +25 °C, SW = 0 in IF and RF locking
state)

■ FUNCTIONAL DESCRIPTION
1. Serial Data Input
Serial data is entered using three pins, Data pin, Clock pin, and LE pin. Programmable dividers of IF/RF-PLL
sections and programmable reference dividers of IF/RF-PLL sections are controlled individually.
Serial data of binary code 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 latches depending upon the control bit
data setting.

• FC bit Setting
When designing a synthesizer, the FC bit setting depends on the VCO and LPF characteristics.
When the LPF and VCO characteristics are similar to (1) ,
set FC bit “H”.
When the VCO characteristics are similar to (2) ,
set FC bit “L”.

2. Power Saving Mode (Intermittent Mode Control)
• PS Pin Setting
PS pin
Status
H
Normal mode
L
Power saving mode
The intermittent mode control circuit reduces the PLL power consumption.
By setting the PS pin low, the device enters the power saving mode, reducing the current consumption.
See “■ ELECTRICAL CHARACTERISTICS” 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 shown in “■PHASE DETECTOR OUTPUT WAVEFORM 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 start-up 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.
Notes: •When power (VCC) is first applied, the device must be in standby mode and PS = Low, for at least 1 µs.
•PS pin must be set “L” for Power ON.

Notes: • Phase error detection range = −2 π to +2 π
• Pulses on DoIF/RF 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 [s] : i.e. tWU ≥ 153.8 ns when fosc = 13.0 MHz
tWU ≤ 4/fosc [s] : i.e. tWL ≤ 307.7 ns when fosc = 13.0 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.
