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.
