The Intersil HSP45116A is a high-performance quadrature numerically controlled oscillator/modulator that combines a complex NCO and a high-speed 16-bit complex multiplier/accumulator. It allows for multiplication and modulation of complex vectors. The product features a 32-bit phase resolution and a frequency resolution better than 0.013Hz at 52MHz. The complex sinusoid output has a spurious free dynamic range greater than 90dBc.
The HSP45116A integrates a high‑performance numerically controlled oscillator (NCO) and a 16‑bit complex multiplier/accumulator (CMAC) on a single CMOS IC. It provides 32‑bit phase resolution, 0.013 Hz tuning resolution at 52 MHz, and supports modulation schemes such as AM, FM, PSK, FSK, QAM, as well as polar‑to‑Cartesian conversion.
The datasheet includes a block diagram, pinout, detailed pin descriptions, functional description, timing diagrams, package dimensions, and ordering information for the 160‑lead MQFP package. Key performance figures such as spurious‑free dynamic range (>90 dBc) and a maximum sample rate of 40 MHz are also listed.
