Product Summary
The LMX1601TMB is a Low Cost Dual Frequency Synthesizer. It is designed to be used in a local oscillator subsystem for a radio transceiver. The LMX1601TMB is fabricated using National’s 0.5u ABiC V silicon BiCMOS process. It contains two dual modulus prescalers, four programmable counters, two phase detectors and two selectable gain charge pumps necessary to provide the control voltage for two external loop filters and VCO loops. Digital filtered lock detects for both PLLs are included. Data is transferred into the LMX1600/01/02 via a MICROWIRE. Serial interface (Data, Clock, LE). The applications of the LMX1601TMB include Cordless/Cellular/PCS phones, other digital mobile phones.
