General Description
The LMX2306/16/26 are monolithic, integrated frequency
synthesizers with prescalers that are designed to be used to
generate a very stable low noise signal for controlling the
local oscillator of an RF transceiver. They are fabricated
using National’s ABiC V silicon BiCMOS 0.5 process.
The LMX2306 contains a 8/9 dual modulus prescaler while
the LMX2316 and the LMX2326 have a 32/33 dual modulus
prescaler. The LMX2306/16/26 employ a digital phase
locked loop technique. When combined with a high quality
reference oscillator and loop filter, the LMX2306/16/26 pro-
vide the feedback tuning voltage for a voltage controlled
oscillator to generate a low phase noise local oscillator sig-
nal. Serial data is transferred into the LMX2306/16/26 via a
three wire interface (Data, Enable, Clock). Supply voltage
can range from 2.3V to 5.5V. The LMX2306/16/26 feature
ultra low current consumption; LMX2306 - 1.7 mA at 3V,
LMX2316 - 2.5 mA at 3V, and LMX2326 - 4.7 mA at 3V.
The LMX2306/16/26 synthesizers are available in a 16-pin
TSSOP surface mount plastic package.
