SERIAL INPUT PLL FREQUENCY SYNTHESIZER WITH 2.0GHZ PRESCALER

The Fujitsu MB1507 is a single chip serial input PLL frequency synthesizer designed for Broadcast Satelite tuner and cellular telephone applications. It contains a 2.0 GHZ dual modulus prescaler which enables pulse swallow function, and an analog switch to speed up lock up time. It operates supply voltage of 5.0V typ. and dissipates 18mA typ. of current realized through the use of Fujitsu’s unique U-ESBIC Bi-CMOS technology.

? High operating frequency: fIN MAX=2.0GHZ (PIN MIN=–4dBm)

? Pulse swallow function: 128/129 or 256/257

? Low supply current: ICC=18mA typ.

? Serial input 19-bit programmable divider consisting of:

Binary 8-bit swallow counter: 0 to 255
