HSP45116GC-15

Programmable Timers And Oscillators Overview

The HSP45116GC-15 is a high-performance Numerically Controlled Oscillator (NCO) and Modulator manufactured by Harris Corporation. It integrates an NCO with a high-speed 16-bit Complex Multiplier/Accumulator (CMAC) on a single CMOS chip. The device supports quadrature modulation and demodulation by multiplying external complex vectors with internally generated sine and cosine waveforms. Key specifications include 32-bit frequency control, 16-bit phase modulation, and a tuning resolution of 0.006 Hz at the 15 MHz operating frequency. Spurious frequency components are maintained below -90 dBc.

Programmable Timers And Oscillators Part Context

This component belongs to the HSP45116 series, which combines NCO and CMAC functions. The 'GC' suffix typically denotes a specific grade or package variant within the Harris/Intersil portfolio, while '-15' indicates the 15 MHz version of the oscillator. Harris Corporation was acquired by Renesas Electronics, and this part represents legacy high-speed analog-digital hybrid technology.
