General Description
The LMX233xU devices are high performance frequency
synthesizers with integrated dual modulus prescalers. The
LMX233xU devices are designed for use as RF and IF local
oscillators for dual conversion radio transceivers.
A 32/33 or a 64/65 prescale ratio can be selected for the 2.5
GHz LMX2330U RF synthesizer. A 64/65 or a 128/129 pres-
cale ratio can be selected for both the LMX2331U and
LMX2332U RF synthesizers. The IF circuitry contains an 8/9
or a 16/17 prescaler. Using a proprietary digital phase locked
loop technique, the LMX233xU devices generate very
stable, low noise control signals for RF and IF voltage con-
trolled oscillators. Both the RF and IF synthesizers include a
two-level programmable charge pump. The RF synthesizer
has dedicated Fastlock circuitry.
Serial data is transferred to the devices via a three-wire
interface (Data, LE, Clock). Supply voltages from 2.7V to
5.5V are supported. The LMX233xU family features ultra low
current consumption:
LMX2330U (2.5 GHz)—3.3 mA, LMX2331U (2.0 GHz)
—2.9 mA, LMX2332U (1.2 GHz)—2.5 mA at 3.0V.
The LMX233xU devices are available in 20-Pin TSSOP and
24-Pin CSP surface mount plastic packages.
