    General Description

    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 adjustable. 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 performance. When combined with a high quality reference oscillator, the LMX2531 generates very stable, low noise local oscillator signals for up and down conversion in wireless communication devices. The LMX2531 is a monolithic integrated circuit, fabricated in an advanced BiCMOS process. There are several different versions of this product in order to accommodate different frequency bands.

    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 Leadframe Package (LLP).

    Reliability Metrics

    Part Number Process EFR Reject EFR Sample Size PPM LTA Rejects LTA Device Hours FITS MTTF (Hours)
    LMX2531LQ2080EBICMOS8214113142016775003475995205
    LMX2531LQX2080EBICMOS8214113142016775003475995205

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
