ADF4218LBRUZ: Low Power dual RF/IF Integer-N PLL
The ADF4218L Synthesizer IC when combined with a VCO and loop filter forms a complete phased locked loop (PLL). This solution from ADI creates state-of-the-art LO's (local oscillator) for the upconversion and downconversion of RF signals in Wireless applications. The PLL consists of a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, programmable A and B counters and a dual-modulus prescaler (P/P+1).
The ADF4217L and ADF4218L are low current consumption improvements on the released ADF4217 and ADF4218 and are available in TSSOP and MLF (LFCSP). The ADF4219L is a Phase Noise upgrade & pin compatible to the LMX2370 from National Semiconductor and is available in both TSSOP and MLF (Cason).
Sales Collateral Available: Full data sheet with performance graphs, press release, circuit simulation included in ADISimPLL released on February 1, 2002, evaluation board and software available.
