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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
