General Description
The LMX1600/01/02 is part of a family of monolithic
integrated dual frequency synthesizers designed to be used
in a local oscillator subsystem for a radio transceiver. It is
fabricated 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
control voltage for two external loop filters and VCO loops.
Digital 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
CC
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.
