General Description
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.
