The Fujitsu MB15E03 is serial input Phase Locked Loop (PLL) frequency synthesizer with a 1.2 GHz prescaler. A
64/65 or a 128/129 can be selected for the prescaler that enables pulse swallow operation.
The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 3.5 mA typ. This
operates with a supply voltage of 3.0 V (typ.).
Furthermore, a super charger circuit is included to get a fast tuning as well as low noise performance. As a result
of this, MB15E03 is ideally suitable for digital mobile communications, such as GSM (Global System for Mobile
Communications).

Serial data is processed using the Data, Clock, and LE pins. Ser ial data controls the programmable reference
divider and the programmable divider separately.
Binary serial data is entered through the Data pin.
One bit of data is shifted into the shift register on the rising edge of the clock. When the load enable pin is high,
stored data is latched according to the control bit data as follows:

Relation between the FC input and phase characteristics
The FC bit changes the phase characteristics of the phase comparator. Both the internal charge pump output level
(DO) and the phase comparator output (φR, φP) are reversed according to the FC bit. Also, the monitor pin (fOUT)
output is controlled by the FC bit. The relationship between the FC bit and each of DO, φR, and φP is shown below.
When designing a synthesizer, the FC pin setting depends on the VCO and LPF characteristics.
∗: When the LPF and VCO characteristics are
similar to (1), set FC bit high.
∗: When the VCO characteristics are similar to
(2), set FC bit low.

Power Saving Mode (Intermittent Mode Control Circuit)
Setting a PS pin to Low, the IC enters into power saving mode resultatly current sonsumption can be limited to
10µA (max.). Setting PS pin to High, power saving mode is released so that the IC works normally.
In addition, the intermittent operation control circuit is included which helps smooth start up from the power saving
mode. In general, the power consumption can be sa ved by the intermittent operation that pow ering 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.
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 10 µA (max.).
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.
Note: •
While the power saving mode is executed, ZC pin should be set at ”H” or open. If ZC is set at ”L”
during power saving mode, approximately 10 µA current flows.
•
PS pin must be set ”L” at Power-ON.
•
The power saving mode can be released (PS : L
•
During the power saving mode, it is possible to input the serial data.

CAUTION:
Customers considering the use of our products in special
applications where failure or abnormal operation may directly
affect human lives or cause physical injury or property damage,
or where extremely high levels of reliability are demanded (such
as aerospace systems, atomic energy controls, sea floor
repeaters, vehicle operating controls, medical devices for life
support, etc.) are requested to consult with FUJITSU sales
representatives before such use. The company will not be
responsible for damages arising from such use without prior
approval.
Any semiconductor devices have inherently a certain rate of
failure. You must protect against injury, damage or loss from
such failures by incorporating safety design measures into your
facility and equipment such as redundancy, fire protection, and
prevention of over-current levels and other abnormal operating
conditions.
