The LMX2350/2352 is part of a family of monolithic integrated fractional N/ Integer N
frequency synthesizers designed to be used in a local oscillator subsystem for a radio
transceiver. It is fabricated using National's 0.5[micro] ABiC V silicon BiCMOS process.
The LMX2350/2352 contains dual modulus prescalers along with modulo 15 or 16
fractional compensation circuitry in the RF divider. A 16/17 or 32/33 prescale ratio can be
selected for the LMX2350, and the LMX2352 provides 8/9 or 16/17 prescale ratios. The IF
circuitry for both the LMX2350 and LMX2352 contains an 8/9 prescaler, and is fully
programmable. Using a fractional N phase locked loop technique, the LMX2350 /52 can
generate very stable low noise control signals for UHF and VHF voltage controlled
oscillators (VCO's).
For the RF PLL, a highly flexible 16 level programmable charge pump supplies output
current magnitudes from 100[micro]A to 1.6mA. Two uncommitted CMOS outputs can be
used to provide external control signals, or configured to FastLock mode. Serial data is
