Apr 2000 HSP50415EVAL1 Evaluation Kit
The HSP50415EVAL1 is an evaluation kit for the HSP50415
wideband programmable modulator. The kit consists of an
evaluation Circuit Card Assembly (CCA) complete with the
HSP50415 device and additional circuitry to provide for
control via a computer parallel port. Windows based
demonstration software is provided for full user
programmability and control of all HSP50415 operational
modes. The evaluation board provides digital outputs which
are accessible through a standard logic analyzer header. It
also provides both single ended and differential analog
outputs via standard SMA connectors. Documentation
includes a user’s manual, full evaluation board schematics
and PCB layout materials. Special filter files, pattern files and
example configuration script files are included for quickly
configuring the board. Features Evaluation CCA Complete With HSP50415 Wideband

HSP50415 В® Data Sheet April 23, 2007 Wideband Programmable Modulator
(WPM) FN4559.6 Features Output Sample Rates to 100MSPS 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. Input Data Rates Up to 25MSPS (I/Q) 32-Bit Programmable Carrier NCO X/SIN(X) Rolloff Compensation Programmable I and Q Shaping FIR Filters:
-Up to 24 Symbol Span Fixed or NCO Controlled Interpolation:
-Interpolation Range . 4 to >128k …
