PMB2341 10-pin Single PLL

The PMB 2341 is a monolithic, low power, Package high performance phase-locked-loop (PLL) frequency synthesizer. It is primarily designed to be used for very stable low noise LO signals in mobile communication systems such as GSM, PCN (GSM 1800), PCS and PDC. The wide range of divider rations also allows application in modern analog systems. 0.2 0.5 3.0 3.0.
