Overview

LMX3305 Triple Phase Locked Loop for RF Personal Communications PRELIMINARY August 2000 LMX3305 Triple Phase Locked Loop for RF Personal Communications General Description The LMX3305 contains three Phase Locked Loops (PLL) on a single chip.
It has a RF PLL, an IF Rx PLL and an IF Tx PLL for CDMA applications.
The RF fractional-N PLL uses a 16/17/20/21 quadruple modulus prescaler for PCS application and a 8/9/12/13 quadruple modulus prescaler for cellular application.
Both quadruple modulus prescalers offer modulo 1 through 16 fractional compensation circuitry.
The RF fractional-N PLL can be programmed to operate from 800 MHz to 1400MHz in cellular band and 1200MHz to 2300 MHz in PCS band.
