Description
The Hewlett-Packard HPMX-5002
IF Modulator/Demodulator
provides all of the active compo-
nents necessary for the demodula-
tion of a downconverted DECT
signal. Designed specifically for
DECT, the HPMX-5002 contains a
down-conversion mixer (to a 2nd
IF), limiting amplifier chain,
discriminator/data slicer, lock
detector, and RSSI circuits. The
LO2 generation is also included
on-chip, via a VCO, dividers, and
phase/frequency detector. The
divide ratios are programmable to
support reference frequencies of
either 9, 12, or 16 times the DECT
bit rate of 1.152␣ MHz allowing the
use of common, low cost crystals.
The LO2 VCO can also be utilized in
transmit mode by directly modulat-
ing the external VCO tank. An AGC
loop in the buffered VCO output
suppresses harmonics and reduces
signal level variability.
The HPMX-5002 is designed to meet
the size and power demands of
portable applications. Battery cell
count and cost are reduced due to
the 2.7 V minimum supply voltage.
The TQFP-48 package, combined
with the high level of integration,
means smaller footprints and fewer
components. Flexible chip biasing
takes full advantage of the power
savings inherent in time-duplexed
systems such as DECT.
