HSP50415
Wideband Programmable Modulator
(WPM)
The HSP50415 Wideband Programmable Modulator (WPM)
is a quadrature amplitude modulator/upconverter designed
for wideband digital modulation. The WPM combines
shaping and interpolation filters, a complex modulator, timing
and carrier NCOs and dual DACs into a single package.
The HSP50415 supports vector modulation, accepting up to
16-bit In phase (I) and Quadrature (Q) samples to generate
virtually any quadrature AM or PM modulation format. A
constellation mapper and 24 Symbol span interpolation
shaping filter is provided for the input baseband signals. Gain
adjustment is provided after the shaping FIR filter. A timing
error generator in the input section allows the on-chip timing
NCO to track the input timing.
The WPM includes a Numerically Controlled Oscillator
(NCO) driven interpolation filter, which allows the input and
output sample rate to have a non-integer or variable
relationship. This re-sampling feature simplifies use of
sample rates that do not have harmonic or integer frequency
relationships to the input data rate and decouples the carrier
from the DATACLK.
A complex quadrature modulator modulates the baseband
data on a programmable carrier center frequency. The
WPM offers digital output spurious Free Dynamic Range
(SFDR) that exceeds 70dB at the maximum output sample
rate of 100MSPS, for input sample rates as high as
25MSPS. X/SIN(X) rolloff compensation filtering is
provided. Real 14-bit digital output data is available prior to
the 12-bit DACs providing 20mA full scale output current.
