MB15F72SP - Dual Serial Input PLL Frequency Synthesizer

General Description

The Fujitsu MB15F72SP is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1300 MHz and a 350 MHz prescalers.

A 64/65 or a 128/129 for the 1300 MHz prescaler, and a 8/9 or a 16/17 for the 350 MHz prescaler can be selected for the prescaler that enables pulse swallow operation.

Key Features

  • High frequency operation:RF synthesizer: 1300 MHz max :IF synthesizer: 350 MHz max.
  • Low power supply voltage: VCC = 2.4 to 3.6 V.
  • Ultra Low power supply current:ICC = 2.7 mA typ. (VCC = Vp = 2.7 V, SWIF = SWRF = 0, Ta = +25°C, in IF, RF locking state).
  • Direct power saving function:Power supply current in power saving mode Typ. 0.1 µA (VCC = Vp = 2.7 V, Ta = +25°C) Max. 10 µA (VCC = Vp = 2.7 V) (Continued) s.

www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-21363-2E ASSP Dual Serial Input PLL Frequency Synthesizer MB15F72SP s DESCRIPTION The Fujitsu MB15F72SP is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1300 MHz and a 350 MHz prescalers. A 64/65 or a 128/129 for the 1300 MHz prescaler, and a 8/9 or a 16/17 for the 350 MHz prescaler can be selected for the prescaler that enables pulse swallow operation. MB15F72SP has the same configuration with MB15F02 or MB15F02L. The BiCMOS process is used , as a result a supply current is typically 2.7 mA typ. at 2.7 V.The supply voltage range is from 2.4 V to 3.6 V. A refined charge pump supplies well-balanced output current with 1.5 mA and 6 mA selectable by serial data.
