MITSUBISHI ICs (Cordless Telephone) 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 the IC to directly s ignal enter up to 500MHz in the TX and up TXOUT to 1GHz in the RX.This IC also contains VCO oscillation-Tr in TXVCC the TX and RX,2-multiple circuit f or transmission output and TXB double balance ty pe mixer f or the 1st intermediate f requency TXE (1st IF).
