Description

The HM6P5331 of full CMOS monolithic, dual frequency

synthesizer is to be used as a local oscillator for RF and IF

of a dual conversion transceiver. It is fabricated using

Hyundai’s standard CMOS process.

HM6P5331 contains dual modulus prescalers. A 64/65 or

a 128/129 prescaler can be selected for RF synthesizer

and a 8/9 or 16/17 prescaler can be selected for IF

synthesizer. Using digital phase locked loop technique,

HM6P5331 provides the tuning voltage for voltage

controlled oscillators to generate very stable low noise RF

& IF local oscillator signals. Serial data is transferred into

the HM6P5331 via three wire interface (Data, Enable,

Clock). Supply voltage can range from 2.7 to 3.6 V.

HM6P5331 features very low current consumption; 4.4mA

at 3.0V.

HM6P5331 is available in a TSSOP 20-pin, LGA(Leadless

Grid Array) 24-pin surface mount plastic package.
