PLLatinum ™ Low Power Dual Frequency Synthesizer for
RF Personal Communications
LMX2330L 2.5 GHz/510 MHz
LMX2331L 2.0 GHz/510 MHz
LMX2332L 1.2 GHz/510 MHz
General Description
The LMX233XL family of monolithic, integrated dual frequen-
cy synthesizers, including prescalers, is to be used as a local
oscillator for RF and first IF of a dual conversion transceiver.
It is fabricated using National's 0.5μ ABiC V silicon BiCMOS
process.
The LMX233XL contains dual modulus prescalers. A 64/65
or a 128/129 prescaler (32/33 or 64/65 in the 2.5 GHz
LMX2330L) can be selected for the RF synthesizer and a 8/9
or a 16/17 prescaler can be selected for the IF synthesizer.
LMX233XL, which employs a digital phase locked loop tech-
nique, combined with a high quality reference oscillator, pro-
vides the tuning voltages for voltage controlled oscillators to
generate very stable, low noise signals for RF and IF local
oscillators. Serial data is transferred into the LMX233XL via
a three wire interface (Data, Enable, Clock). Supply voltage
can range from 2.7V to 5.5V. The LMX233XL family features
very low current consumption;
LMX2330L—5.0 mA at 3V, LMX2331L—4.0 mA at 3V,
LMX2332L—3.0 mA at 3V.
The LMX233XL are available in a TSSOP 20-pin, CSP 24-pin
surface mount plastic package, and thin CSP 20-pin surface
mount plastic package.
