Wideband Programmable Modulator

(WPM)

Features

• Output Sample Rates. . . . . . . . . . . . . . . . . . to 100MSPS

• Input Data Rates . . . . . . . . . . . . . . . .Up to 25MSPS (I/Q)

• 32-Bit Programmable Carrier NCO

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.

• X/SIN(X) Rolloff Compensation

• Programmable I and Q Shaping FIR Filters:

- Up to 24 Symbol Span

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.

• Fixed or NCO Controlled Interpolation:

- Interpolation Range . . . . . . . . . . . . . . . . . . 4 to > 128K

- Digital PLL to Lock to Input Symbol Clock

• Digital Signal Processing Capable of >70dB SFDR

• Dual 12-bit D/A Processing Capable of >50 dB SFDR

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.

Applications

• Wide-Band Digital Modulation

• Base Station Modulators

• HSP50415EVAL1 Evaluation Board Available

Ordering Information

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
