LMX2515
PLLatinum
Frequency Synthesizer System
with Integrated VCO
General Description
LMX2515 is a highly integrated, high performance, low
power frequency synthesizer system optimized for Japan
PDC mobile handsets. Using a proprietary digital phase
locked loop technique, LMX2515 generates very stable, low
noise local oscillator signals for up and down conversion in
wireless communications devices.
LMX2515 includes a voltage controlled oscillator (VCO), a
loop filter, and a fractional-N RF PLL based on a delta sigma
modulator. In concert these blocks form a closed loop RF
synthesizer system. The LMX2515LQ0701 supports the Ja-
pan PDC800 band and the LMX2515LQ1321 supports Ja-
pan PDC1500 band.
Serial data is transferred to the device via a three-wire
MICROWIRE interface (DATA, LE, CLK).
Operating supply voltage ranges from 2.5 V to 3.3 V.
LMX2515 features low current consumption.
LMX2515 is available in a 28-pin leadless leadframe pack-
age (LLP).
