MB15F08SL - Dual Serial Input PLL Frequency Synthesizer

General Description

The Fujitsu MB15F08SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2500 MHz and a 1100 MHz prescalers.

The 2500 MHz prescaler, and 1100 MHz prescaler have a dual modulus division ratio of 32/ 33 or 64/65 and 16/17 or 32/33 enabling pulse swallow operation.

Key Features

  • High frequency operation: RX synthesizer: 2500 MHz max TX synthesizer: 1100 MHz max.
  • Low power supply voltage: VCC = 2.4 to 3.6 V.
  • Ultra Low power supply current: ICC = 7.0 mA typ. (VCC = 2.7 V, Ta = +25°C, in TX, RX locking state) ICC = 7.5 mA typ. (VCC = 3.0 V, Ta = +25°C, in TX, RX locking state).
  • Direct power saving function: Power supply current in power saving mode Typ. 0.1 µA (VCC = 3V, Ta = +25°C), Max. 10 µA (VCC = 3V).
  • Dual modulus prescale.

www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-21362-2E ASSP Dual Serial Input PLL Frequency Synthesizer MB15F08SL s DESCRIPTION The Fujitsu MB15F08SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2500 MHz and a 1100 MHz prescalers. The 2500 MHz prescaler, and 1100 MHz prescaler have a dual modulus division ratio of 32/ 33 or 64/65 and 16/17 or 32/33 enabling pulse swallow operation. The supply voltage range is between 2.4 V and 3.6 V. The MB15F08SL uses the latest BiCMOS process. As a result, the supply current is typically 7.0 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. MB15F08SL is ideally suited for wireless mobile communications.
