M64884FP
Transistor for VCO,1st IF MIX,2-multiple circuit built-in 500MHz/1GHz Dual PLL Synthesizer
1.DESCRIPTION
The M64884FP is a 2-sy stem 1-chip PLL f requency s y nthe-
sizer IC designed of Analog cordless telephone f or North
America (ISM band) that can directly enter signal up to 500-
MHz in the TX and up to 1GHz in the RX.
Adoption of high perf ormance Bi-CMOS process enables low
power consumption ty pe 2-modulus prescaler to be built in ^TXGND1
