2 / 19 page  LMX2335/LMX2336/LMX2337 PLLatinum™ Dual Frequency Synthesizer for RF Personal Communications LMX2335 1.1 GHz/1.1 GHz LMX2336 2.0 GHz/1.1 GHz LMX2337 550 MHz/550 MHz General Description The LMX2335, LMX2336 and LMX2337 are monolithic, inte- grated dual frequency synthesizers, including two high fre- quency prescalers, and are designed for applications requir- ing two RF phase-lock loops. They are fabricated using National’s ABiC IV silicon BiCMOS process. The LMX2335/36/37 contains two dual modulus prescalers. A 64/65 or a 128/129 prescaler can be selected for each RF synthesizer. A second reference divider chain is included in the IC for improved system noise. LMX2335/36/37, which employ a digital phase locked loop technique, combined with a high quality reference oscillator and loop filters, provide the tuning voltages for voltage controlled oscillators to generate very stable low noise RF local oscillator signals. Serial data is transferred into the LMX2335/36/37 via a three wire interface (Data, Enable, Clock). Supply voltage can range from 2.7V to 5.5V. The LMX2335/36/37 feature very low current consumption; LMX2335/37 −10 mA at 3V, LMX2336 −13 mA at 3V. The LMX2335/37 are available in both a JEDEC SO and TSSOP 16-pin surface mount plastic package. The LMX2336 is available in a TSSOP 20-pin sur- face mount plastic package.
