DATASHEET HSP50415 FN4559 Rev 6.00 Wideband Programmable Modulator (WPM) Apr 23, 2007 The HSP50415 Wideband Programmable Modulator (WPM) Features is a quadrature amplitude modulator/upconverter designed Output Sample Rates to 100MSPS for wideband digital modulation. The WPM combines shaping and interpolation filters, a complex modulator, timing Input Data Rates Up to 25MSPS (I/Q) and carrier NCOs and dual DACs into a single package. 32-Bit Programmable Carrier NCO The HSP50415 supports vector modulation, accepting up to X/SIN(X) Rolloff Compensation 16-bit In phase (I) and Quadrature (Q) samples to generate Programmable I and Q Shaping FIR Filters: virtually any quadrature AM or PM modulation format. A - Up to 24 Symbol Span constellation mapper and 24 Symbol span interpolation shaping filter is provided for the input baseband signals. Gain Fixed or NCO Controlled Interpolation: adjustment is provided after the shaping FIR filter. A timing error - Interpolation Range . 4 to >128k generator in the input section allows the on-chip timing NCO to - Digital PLL to Lock to Input Symbol Clock track the input timing. Digital Signal Processing Capable of >70dB SFDR The WPM includes a Numerically Controlled Oscillator Dual 12-bit D/A Processing Capable of >50dB SFDR (NCO) driven interpolation filter, which allows the input and output sample rate to have a non-integer or variable Pb-Free Plus Anneal Available (RoHS Compliant) relationship. This re-sampling feature simplifies use of sample rates that do not have harmonic or integer frequency Applications relationships to the input data rate and decouples the carrier Wide-Band Digital Modulation from the DATACLK. Base Station Modulators A complex quadrature modulator modulates the baseband HSP50415EVAL1 Evaluation Board Available 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.
