Pllatinum High Performance Frequency Synthesizer System With Integrated Vco - National Semiconductor

The LMX2531 is a low power, high performance frequency synthesizer system which includes a fully integrated delta- sigma PLL and VCO with fully integrated tank circuit. The third and fourth poles are also integrated and also adjust- able. Also included are integrated ultra-low noise and high precision LDOs for the PLL and VCO which give higher supply noise immunity and also more consistent perfor- mance. When combined with a high quality reference oscil- lator, the LMX2531 generates very stable, low noise local Oscillator signals for up and down conversion in Wireless Communication devices. The LMX2531 is a monolithic inte- grated circuit, fabricated in an advanced BiCMOS process. There are actually several different versions of this product, for which the primary difference is frequency range. Device programming is facilitated using a three-wire MICROWIRE Interface that CAN operate down to 1.8 volts. Supply voltage range is 2.8 to 3.2 Volts. The LMX2531 is available in a 36 pin 6x6x0.8 mm Lead-Free Leadless Lead- frame Package (LLP). By National Semiconductor Corporation
