Dual Serial Input
PLL Frequency Synthesizer
MB15F73UL
■ DESCRIPTION
The Fujitsu Semiconductor 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.

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 (ground
ed) 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 representatives beforehand.

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)

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/
RF-PLL 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
