DESCRIPTION

The Fujitsu MB15F73UV 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.

FEATURES

• High frequency operation : RF synthesizer : 2250 MHz Max

: IF synthesizer : 600 MHz Max

• Low power supply voltage : VCC = 2.4 V to 3.6 V

• Ultra low power supply current : ICC = 3.2 mA Typ

(VCC = 2.7 V, Ta = +25 °C, SWIF = SWRF = 0 in IF/RF locking state)

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

Typ 0.1 µA (VCC = 2.7 V, Ta = +25 °C)

Max 10 µA (VCC = 2.7 V)

• Software selectable charge pump current : 1.5 mA/6.0 mA Typ

• Dual modulus prescaler : 2250 MHz prescaler (64/65 or128/129) /600 MHz prescaler (8/9 or 16/17)

• 23 bit shift register

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

• Serial input programmable divider consisting of:
