General Description
The LMX233XL family of monolithic, integrated dual frequency 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
0.5 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 technique, combined with a high
quality reference oscillator, provides 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.
