ADF4218LBRUZ-REEL7

Clock Generator 10MHz to 3GHz Input 188MHz Output 20Pin TSSOP T/R

Product Details

The ADF4218L Synthesizer IC when combined with a VCO and loop filter forms a complete phased locked loop PLL. This solution from 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.
