MB15F07SL - Dual Serial Input PLL Frequency Synthesizer

General Description

The Fujitsu MB15F07SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with two 1100 MHz prescalers.

The two 1100 MHz prescalers have a dual modulus division ratio of 128/129 or 64/65 enabling pulse swallowing operation.

The supply voltage range is between 2.4 V and 3.6 V.

Key Features

  • High frequency operation: PLL 1, 2: 1100 MHz max.
  • Low power supply voltage: VCC = 2.4 to 3.6 V.
  • Ultra Low power supply current: ICC = 5.0 mA typ. (VCC = 2.7 V, Ta = +25°C, in PLL1, 2 locking state) ICC = 5.5 mA typ. (VCC = 3.0 V, Ta = +25°C, in PLL1, 2 locking state).
  • Direct power saving function: Power supply current in power saving mode Typ. 0.1 µA (VCC = 3.0 V, Ta = +25°C), Max. 10 µA (VCC = 3.0 V).
  • Dual modulus prescaler: 1100 MHz prescaler (64/6.

The two 1100 MHz prescalers have a dual modulus division ratio of 128/129 or 64/65 enabling pulse swallowing operation. The supply voltage range is between 2.4 V and 3.6 V. The MB15F07SL uses the latest BiCMOS process. As a result, the supply current is typically 5 mA at 2.7 V. A refined charge pump supplies a well-balanced output current of 1.5 mA or 6 mA. The charge pump current is selectable by serial data. MB15F07SL is ideally suited for wireless mobile communications, such as GSM and PDC.
