1.1 GHz Frequency Synthesizer
for RF Personal Communications
General Description
The LMX1501A and the LMX1511 are high performance fre-
quency synthesizers with integrated prescalers designed for
RF operation up to 1.1 GHz. They are fabricated using Na-
tional’s ABiC IV BiCMOS process.
The LMX1501A and the LMX1511 contain dual modulus
prescalers which can select either a 64/65 or a 128/129
divide ratio at input frequencies of up to 1.1 GHz. Using a
proprietary

LMX1501A/11’s linear phase detector characteristics can

technique,
the
Serial data is transferred into the LMX1501A and the
LMX1511 via a three line MICROWIRE
TM
interface (Data,
Enable, Clock). Supply voltage can range from 2.7V to 5.5V.
The LMX1501A and the LMX1511 feature very low current
consumption, typically 6 mA at 3V.
The LMX1501A is available in a JEDEC 16-pin surface
mount plastic package. The LMX1511 is available in a
TSSOP 20-pin surface mount plastic package.
