LMX3305 Datasheet (National Semiconductor)

LMX3305, Triple Phase Locked Loop

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.
