General Description
The LMX233XL family of monolithic, integrated dual fre-
quency 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,
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.
