Integrated Circuit Systems, Inc. ICS31202 Preliminary Product Preview Dual Frequency Synthesizer General Description The ICS31202 is an integrated Dual Frequency Synthesizer designed for RF Personal Communication systems requiring two independent frequencies. It is one of the lowest cost and smallest size solutions for 900MHz applications. The ICS31202 contains two dual modulus prescalers. A 32/ 33 prescaler can be selected for each RF synthesizer . A common reference divider chain is included for required frequency resolution. Combined with a high quality reference oscillator and loop filter , the ICS31202 provides the tuning voltages for the external VCO's to generate very stable, low noise RF Local Oscillator signals. Serial data is transferred using a three wire interface.
