LMX2531LQ2080E/NOPB(购买请点击) is a low power, high performance frequencysynthesizer system which includes a fully integrated deltasigmaPLL and VCO with fully integrated tank circuit. The thirdand fourth poles are also integrated and also adjustable. Alsoincluded are integrated ultra-low noise and high precisionLDOs for the PLL and VCO which give higher supply noiseimmunity and also more consistent performance. When combinedwith a high quality reference oscillator, the LMX2531LQ2080E/NOPB generates very stable, low noise local oscillator signals for upand down conversion in wireless communication devices.
The LMX2531LQ2080E/NOPB(购买请点击) is a monolithic integrated circuit, fabricated inan advanced BiCMOS process. There are several differentversions of this product in order to accomdate different frequencybands.
Device programming is facilitated using a three-wireMICROWIRE Interface that can operate down to 1.8 volts.
Supply voltage range is 2.8 to 3.2 Volts. The LMX2531LQ2080E/NOPB(购买请点击) isavailable in a 36 pin 6x6x0.8 mm Lead-Free Leadless LeadframePackage (LLP).
