LMX2346/LMX2347
PLLatinum Frequency Synthesizer for RF Personal
Communications
LMX2346
2.0 GHz
LMX2347
2.5 GHz
General Description
The LMX2346/7 are high performance frequency synthesiz-
ers with an integrated 32/33 dual modulus prescaler. The
LMX2346 is designed for RF operation up to 2.0 GHz. The
LMX2347 is designed for RF operation up to 2.5 GHz. Using
a proprietary digital phase locked loop technique, the
LMX2346/7 generates very stable, low noise control signals
for UHF and VHF voltage controlled oscillators.
Serial data is transferred into the LMX2346/7 via a three-line
MICROWIRE interface (DATA, LE, CLOCK). Supply voltage
range is from 2.7V to 5.5V. The charge pump provides 4 mA
output current.
The LMX2346/7 are manufactured using National’s 0.5
ABiC V silicon BiCMOS process and is available in 16-pin
TSSOP and 16-pin CSP packages.
