n 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.

n FEATURES

• High frequency operation: RF synthesizer : 6000MHz max

IF synthesizer : : 1500MHz max

• Low power supply voltage: V CC = 2.7 to 3.6 V

Preliminary. • Ultra Low power supply current : ICC = 9.0 mA typ. (VCC = Vp=3.0V, Ta=25°C, SW=0 in RF, IF locking state)

• Direct power saving function : Power supply current in power saving mode

Typ. 0.1 µA(Vcc=Vp=3.0V, Ta=25 °C), Max. 10 µA(Vcc=Vp=3.0V)

• Dual modulus prescaler : 6000MHz prescaler(16/17 or 32/33, and 1/4divider)

•

1500MHz prescaler(4/5 or 8/9, and 1/4divider)

• Serial input 14-bit programmable reference divider: R = 3 to 16,383

• Serial input programmable divider consisting of:

- Binary 5-bit swallow counter: 0 to 31

- Binary 13-bit programmable counter: 3 to 8191

• On-chip phase comparator for fast lock and low noise

• On-chip phase control for phase comparator

• Operating temperature: Ta = –40 to 85°C
