HFA3524 TM Data Sheet March 2000 File Number 4062.8 2.5GHz/600MHz Dual Frequency Synthesizer The Intersil 2.4GHz PRISM® chip set is a highly integrated six-chip solution for RF modems employing Direct Sequence Spread Spectrum (DSSS) signaling. The HFA3524 600MHz Dual Frequency Synthesizer is one of the six chips in the PRISM chip set (see the Typical Application Diagram). The HFA3524 is a monolithic, integrated dual frequency synthesizer, including prescaler, is to be used as a local oscillator for RF and first IF of a dual conversion transceiver. The HFA3524 contains a dual modulus prescaler. A 32/33 or 64/65 prescaler can be selected for the RF synthesizer and a 8/9 or a 16/17 prescaler can be selected for the IF synthesizer.
