DESCRIPTION
The Fujitsu MB15F76UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 6000MHz and a
1500MHz prescalers. Both IF and RF PLL section have a 1/4 divider. And a 16/17 or a 32/33 for the 6000MHz
prescaler, and a 4/5 or a 8/9 for the 1500MHz prescaler can be selected for the prescaler that enables pulse swallow
operation.
The latest BiCMOS process is used, as a result, a supply current is typically 9.0mA typ. at 3.0V. The supply voltage
range is from 2.7V to 3.6V. A refined charge pump supplies well-balanced output current with 1.5mA and 6mA
selectable by serial data. Fast locking is acheived for adopting the new circuit.
The new package(BCC20) decreases a mount area of MB15F76UL more than 30% comparing with the former
BCC16(for dual PLL).
MB15F76UL is ideally suited for wireless communications, such as W-LAN.

Handling Precautions
(1)
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 both Vcc RF,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.

Power saving mode
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 single PLL, the lock detector, LD, remains high, indicating a locked condition.
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 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.
Note: When power (VCC ) is first applied, the device must be in standby mode, PS=Low, for at least 1µs.

Note: • Phase error detection range = −2π to +2π
• Pulses on DoIF/RF signals are output to prevent dead zone.
• LD output becomes low when phase error is tW U or more.
• LD output becomes high when phase error is t W L 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: i.e. tW U > 200ns when foscin = 10 MHz
tWL < 4/fosc: i.e. t W L < 400ns when foscin = 10 MHz
