MB15F8XUL - Fractional-N / Integer dual PLL Frequency Synthesizers

General Description

The Fujitsu MB15F8xUL series dual PLLs are serial input Frequency synthesizers.

The Fractional-N PLL operates up to 2.6 GHz and the integer PLL operates up to 1200 MHz.

They have built-in dual-modulus prescalers enabling pulse swallow operation and fixed or selectable fractional modulo.

Key Features

  • Fractional-N RF PLL and Integer IF PLL.
  • Very low spurious and phase noise characteristics.
  • Low operating voltage: 2.4 to 3.6 volts.
  • Low operating current: 5.8 to 6 mA (typical).
  • Power-saving current: 0.1µA (typical) Parameter RF/RX Frequency - max. IF/TX Frequency - max Low Power Supply Voltage Low Power Supply Current Prescaler Divide Ratios.
  • Wide operating temperature:.
  • 40 to +85°C.
  • New 30% smaller BCC 20 package.

The Fractional-N PLL operates up to 2.6 GHz and the integer PLL operates up to 1200 MHz. They have built-in dual-modulus prescalers enabling pulse swallow operation and fixed or selectable fractional modulo. The latest advanced BiCMOS technology is used resulting in a super low supply current. A refined charge pump design (Fujitsu’s Super Charger) provides fast tuning along with low spurious noise and phase noise characteristics. The MB15F8xUL series is ideally suited for digital mobile communications, including GSM, DCS1800, PCS1900, IS-136, IS-95 and ISM applications.
