The PMB 2306T PLL is a high speed CMOS IC, especially designed for use in battery powered
radio equipment and mobile telephones. The primary applications will be in digital systems e.g.
GSM, PCN, ADC, JDC and DECT systems. The wide range of dividing ratios also allows application
in modern analog systems
