General DescriptionThe LMX243x devicesare high performance frequency syn-
thesizers with integrated dual modulus prescalers. The
LMX243x devices are designedfor useas RF andIF local
oscillatorsfor dual conversion radio transceivers. 32/33ora 16/17 prescale ratio canbe selectedforthe5.0
GHz LMX2434RF synthesizer.An 8/9ora 16/17 prescale
ratio canbe selectedfor both the LMX2430 and LMX2433 synthesizers. TheIF circuitry containsan 8/9ora 16/17
prescaler. Usinga proprietary digital phase locked loop tech-
nique,the LMX243x devices generate very stable,low noise
control signalsfor RF andIF voltage controlled oscillators.
Both the RF andIF synthesizers includea two-level pro-
grammable charge pump. Both theRF andIF synthesizers
have dedicated Fastlock circuitry with integrated timeout
counters. Furthermore, onlya single word writeis requiredto
powerup and tunethe synthesizerstoa new frequency.
Serial datais transferredto the devices viaa three-wire
interface (DATA, LE, CLK).A low voltage logic interface
allows direct connectionto 1.8V devices. Supply voltages
from 2.25Vto 2.75V are supported. The LMX243x family
features low current consumption:
LMX2430 (3.0 GHz/0.8 GHz)—2.8 mA/1.4 mA, LMX2433
(3.6 GHz/1.7 GHz) —3.2 mA/2.0 mA, LMX2434 (5.0 GHz/
2.5 GHz)—4.6 mA/2.4 mAat 2.50V.
The LMX243x devices are availablein 20-Pin TSSOP and
20-Pin UTCSP surface mount plastic packages.
