MB15F73UL - ASSP Dual Serial Input PLL Frequency Synthesizer

Description

The Fujitsu MB15F73UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2250MHz and a 600MHz prescalers.

A 64/65 or a 128/129 for the 2250MHz prescaler, and a 8/9 or a 16/17 for the 600MHz prescaler can be selected for the prescaler that enables pulse swallow operation.

Features

  • High frequency operation: RF synthesizer : 2250MHz max IF synthesizer : 600MHz max.
  • Low power supply voltage: VCC = 2.4 to 3.6 V.
  • Ultra Low power supply current : ICC = 3.2 mA typ. (VCC = Vp=2.7V, 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=2.7V, Ta=25°C), Max. 10 µA(Vcc=Vp=2.7V).
  • Dual modulus prescaler : 2250MHz prescaler(64/65 or 128/129) / 600MHz prescaler(8/9.

www.DataSheet4U.com Dec. 2000 Edition 2.0 ASSP Dual Serial Input PLL Frequency Synthesizer MB15F73UL n DESCRIPTION The Fujitsu MB15F73UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2250MHz and a 600MHz prescalers. A 64/65 or a 128/129 for the 2250MHz prescaler, and a 8/9 or a 16/17 for the 600MHz 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 3.2mA typ. at 2.7V. The supply voltage range is from 2.4V to 3.6V. A refined charge pump supplies well-balanced output current with 1.5mA and 6mA selectable by serial data. The data format is same as the previous one MB15F03SL, MB15F73SP. Fast locking is acheived for adopting the new circuit.
