Dual Frequency Synthesizer for RF

Personal Communications

LMX2330A 2.5 GHz/510 MHz

LMX2331A 2.0 GHz/510 MHz

LMX2332A 1.2 GHz/510 MHz

General Description

The LMX233xA 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 trans-

ceiver. It is fabricated using National鈥檚 ABiC IV silicon

BiCMOS process.

The LMX233xA contains dual modulus prescalers. A 64/65

or a 128/129 prescaler (32/33 or 64/65 in the 2.5 GHz

LMX2330A) can be selected for the RF synthesizer and a

8/9 or a 16/17 prescaler can be selected for the IF synthe-

sizer. LMX233XA, which employs a digital phase locked loop

technique, combined with a high quality reference oscillator

and loop filters, provides the tuning voltages for voltage con-

trolled oscillators to generate very stable low noise RF and

IF local oscillator signals. Serial data is transferred into the

LMX233xA via a three wire interface (Data, Enable, Clock).

Supply voltage can range from 2.7V to 5.5V. The LMX233xA

family

features

very

low

current

consumption;

LMX2330A 鈥?13 mA at 3V, LMX2331A 鈥?12 mA at 3V,

LMX2332A 鈥?8 mA at 3V.

The LMX233xA are available in a TSSOP 20-pin surface

mount plastic package.
