1.2 GHz Frequency Synthesizer
for RF Personal Communications
General Description
The LMX2314 and the LMX2315 are high performance fre-
quency synthesizers with integrated prescalers designed for
RF operation up to 1.2 GHz. They are fabricated using Na-
tional’s ABiC IV BiCMOS process.
The LMX2314 and the LMX2315 contain dual modulus pre-
scalers which can select either a 64/65 or a 128/129 divide
ratio at input frequencies of up to 1.2 GHz. Using a proprie-
tary digital phase locked loop technique, the LMX2314/15’s
linear phase detector characteristics can generate very sta-
ble, low noise local oscillator signals.
Serial data is transferred into the LMX2314 and the
LMX2315 via a three line MICROWIRE
TM
interface (Data,
Enable, Clock). Supply voltage can range from 2.7V to 5.5V.
The LMX2314 and the LMX2315 feature very low current
consumption, typically 6 mA at 3V.
The LMX2314 is available in a JEDEC 16-pin surface mount
plastic package. The LMX2315 is available in a TSSOP
20-pin surface mount plastic package.
