DESCRIPTION
The Fujitsu MB15E06 is serial input Phase Locked Loop (PLL) frequency synthesizers with a 2.5 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 8 mA typ. This op-
erates 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, MB15E06 is ideally suitable for digital mobile communications, such as GPS (Global Positioning System) ,
Wireless LAN, CATV (CAble TeleVision) etc.

Descriptions
Programmable reference divider input.
Oscillator input connection to a TCXO.
Oscillator output.
Power supply voltage input for the charge pump.
Power supply voltage input.
Charge pump output.
Phase of the charge pump can be reversed by FC input.
Ground.
Prescaler complementary input, and should be grounded via a capacitor.
Prescaler input.
Connection with an external VCO should be done with AC coupling.
Clock input for the 19-bit shift register.
Data is shifted into the shift register on the rising edge of the clock.
(Open is
prohibited.)
Serial data input using binary code.
The last bit of the data is a control bit.
(Open is prohibited.)
Control bit
=
“H” ; Data is transmitted to the programmable reference
counter.
Control bit
=
“L” ; Data is transmitted to the programmable counter.
Load enable signal input
(Open is prohibited.)
When LE is high, the data in the shift register is transferred to a latch,
according to the control bit in the serial data.
Power saving mode control. This pin must be set at “L” at Power-ON.
(Open is prohibited.)
PS
=
“H” ; Normal mode
PS
=
“L” ; Power saving mode
Forced high-impedance control for the charge pump (with internal pull up
resistor.)
ZC
=
“H” ; Normal Do output.
ZC
=
“L” ; Do becomes high impedance.
Lock detect signal output (LD) /phase comparator monitoring
output (fout) .
The output signal is selected by LDS bit in the serial data.
LDS
=
“H” ; outputs fout (fr/fp monitoring output)
LDS
=
“L” ; outputs LD (“H” at locking, “L” at unlocking.)
Phase comparator output for an external charge pump.
Phase comparator output for an external charge pump.

Remark
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.
