LMX2332L

1.2 GHz/510 MHz

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.
