HM6P5331

PRELIMINARY HM6P5331 HM6P5331 – 2.0GHz/500MHz Dual Frequency Synthesizer Features






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. Applications
