2.5GHz/600MHz Dual Frequency

Synthesizer

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. Using a digital phase locked loop technique, the

HFA3524 can generate a very stable, low noise signal for the

RF and IF local oscillator. Serial data is transferred into the

HFA3524 via a three wire interface (Data, Enable, Clock).

Supply voltage can range from 2.7V to 5.5V. The HFA3524

features very low current consumption of 13mA at 3V.
