Product Summary

The LMX1601TMX/NOPB is a pllatinum low cost dual frequency synthesizer. The LMX1601TMX/NOPB is part of a family of monolithic integrated dual frequency synthesizers designed to be used in a local oscillator subsystem for a radio transceiver. It is fabricated using National’s 0.5u ABiC V silicon BiCMOS process. The LMX1601TMX/NOPB 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 LMX1601TMX/NOPB via a MICROWIR serial interface (Data, Clock, LE).
