PLLatinum™ Low Power Dual Frequency Synthesizer for Personal Communications
General Description

The LMX2335L and LMX2336L are monolithic, integrated
dual frequency synthesizers, including two high frequency
prescalers, and are designedfor applications requiring two phase-lock loops. They are fabricated using National’s
0.5µ ABiCV silicon BiCMOS process.
The LMX2335L/36L contains two dual modulus prescalers.A
64/65ora 128/129 prescaler canbe selectedfor each RF
synthesizer.A second reference divider chainis includedin
theICfor improved system noise. The LMX2335L/36L com-
bined witha high quality reference oscillator, two loop filters,
and two external voltage controlled oscillators generates
very stable low noiseRF local oscillator signals.
Serial datais transferred intothe LMX2335L/36Lviaa three
wire interface (Data, Enable, Clock). Supply voltage can
range from 2.7Vto 5.5V. The LMX2335L/36L feature very
low current consumption; LMX2335L 4.0 mAat 5V,
LMX2336L5.5 mAat 5V. The LMX2335Lis availablein SO,
TSSOP and CSP 16-pin surface mount plastic packages.
The LMX2336Lis availableina TSSOP 20-pin and CSP
24-pin surface mount plastic package.
Features
