General Description
The LMX1600/01/02 is part of a family of monolithic inte-
grated dual frequency synthesizers designed to be used in a
local oscillator subsystem for a radio transceiver. It is fabri-
cated using National’s 0.5u ABiC V silicon BiCMOS process.
The LMX1600/01/02 contains two dual modulus prescalers,
four programmable counters, two phase detectors and two
selectable gain charge pumps necessary to provide the con-
trol voltage for two external loop filters and VCO loops. Digi-
tal filtered lock detects for both PLLs are included. Data is
transferred into the LMX1600/01/02 via a MICROWIRE
serial interface (Data, Clock, LE).
V
supply voltage can range from 2.7V to 3.6V. The
LMX1600/01/02 features very low current consumption -
typically 4.0 mA at 3V for LMX1601, 5.0 mA at 3V for
LMX1600 or LMX1602. Powerdown for the PLL is hardware
controlled.
The LMX1600/01/02 is available in a 16 pin TSSOP surface
mount plastic package.
