2.0 GHz PLLatinum Frequency Synthesizer For RF Personal Communications
The LMX2346 LMX2347 are high performance Frequency Synthesizers 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 LMX2347 generates very stable, low noise control signals for UHF and VHF voltage controlled Oscillators
Serial data is transferred into the LMX2346 LMX2347 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 LMX2347 are manufactured using National's 0.5? ABiC V silicon BiCMOS process and is available in 16-pin TSSOP and 16-pin CSP packages.
