MB1511 - Serial Input PLL Frequency Synthesizer

General Description

The Fujitsu MB1511 is a single chip serial input PLL frequency synthesizer designed for VHF tuner and cellular telephone applications.

It contains a 1.1 GHz dual modulus prescaler which enables pulse swallow function, and an analog switch to speed up lock up time.

Key Features

  • Low power supply voltage: VCC = 2.7 to 5.5 V High operating frequency: fIN MAX = 1.1 GHz (VIN MIN =.
  • 10dBm) Pulse swallow function: 64/65 or 128/129 Low supply current: ICC = 7 mA typ. Serial input 18-bit programmable divider consisting of: Binary 7-bit swallow counter: 0 to 127 Binary 11-bit programmable counter: 16 to 2047.
  • Serial input 15-bit programmable reference divider consisting of: Binary 14-bit programmable reference co.
