Product details
Overview
HSP45116AVC-52Z from Intersil is a 52MHz numerically controlled oscillator/modulator IC integrating a 32-bit phase/frequency control section, 16-bit quadrature sine/cosine generator, and 16-bit complex multiplier/accumulator (CMAC) in a single monolithic CMOS device. It delivers >90dBc spurious-free dynamic range, programmable 20-bit output resolution, and supports real-time quadrature modulation/demodulation for RF signal processing at up to 40MHz sample rate.
For engineers reviewing the HSP45116AVC-52Z datasheet, HSP45116AVC-52Z pinout, HSP45116AVC-52Z application, or HSP45116AVC-52Z equivalent, this device serves as a high-precision digital frequency synthesis and complex vector modulation engine - particularly relevant for direct digital synthesis (DDS), QAM/PSK modulators, PLL-based receivers, and FFT butterfly computation in communications infrastructure.
Technical Context
The HSP45116AVC-52Z implements a fully static CMOS architecture with three synchronized functional blocks: a 32-bit phase accumulator generating the sine/cosine argument, a 20-bit address ROM lookup producing 16-bit two's complement sin/cos outputs, and a 33-bit complex multiplier feeding dual 20-bit accumulators. Its phase resolution enables 0.013Hz tuning step at 52MHz clock.
Control is executed via parallel microprocessor interface (C0–C15, AD0/AD1, CS, WR) and dedicated logic lines (ENPHREG, ENCFREG, MODPI/2PI, ACC, BINFMT), supporting both CW synthesis and dynamic FM/PSK/FSK modulation. Output multiplexing (OUTMUX0/1), rounding (RND), and block floating-point growth detection (DET0/DET1) are hardware-configurable without firmware overhead.

Equivalent & Alternatives
The following parts are listed as comparable options for similar numerically controlled oscillator/modulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9858ASTZ | Integrated 10-bit DAC, 1GSPS system clock, no on-chip CMAC; higher integration but lower precision and no complex accumulation | Better suited for wideband analog output applications; lacks hardware FFT support and programmable accumulation | Choose AD9858ASTZ when analog output and ultra-high speed (>100MHz) are required over digital signal processing flexibility |
| MAX2190ETM+ | RF front-end IC with integrated mixer, LNA, and IF amplifier; no NCO or digital modulation capability | Designed for receive-path signal conditioning only; requires external digital modulator for transmit functions | Choose MAX2190ETM+ only for analog IF receiver chain integration - not a functional alternative for digital NCO/CMAC tasks |
Compared with AD9858ASTZ and MAX2190ETM+, the HSP45116AVC-52Z uniquely combines high-resolution NCO synthesis with hardware-accelerated complex multiplication and accumulation - making it irreplaceable for digital-domain quadrature processing where bit-true reproducibility, programmable output formatting, and FFT-ready growth detection are mandatory.

FAQ
What is the primary function of the HSP45116AVC-52Z?
The HSP45116AVC-52Z is a numerically controlled oscillator/modulator IC combining a 32-bit NCO and a 16-bit complex multiplier/accumulator. Its primary function is to generate high-purity quadrature sinusoids and perform real-time complex multiplication for modulation, demodulation, and FFT computation. The HSP45116AVC-52Z operates at up to 52MHz and delivers >90dBc spurious-free dynamic range, making it suitable for demanding RF and digital signal processing applications.
Does the HSP45116AVC-52Z support QPSK modulation?
Yes, the HSP45116AVC-52Z supports QPSK modulation via its external phase modulation interface (MOD0/MOD1 and PMSEL pins). When PMSEL is low, MOD0 and MOD1 directly load 2-bit phase offsets (0°, 90°, 180°, or 270°) into the most significant bits of the phase register, enabling hardware-accelerated QPSK symbol mapping without CPU intervention. This functionality is explicitly documented in Table 2 of the FN4156 datasheet for the HSP45116AVC-52Z.
What is the purpose of the RBYTILD pin on the HSP45116AVC-52Z?
The RBYTILD (ROM Bypass / Timer Load) pin on the HSP45116AVC-52Z, when asserted low, bypasses the sine/cosine ROM lookup and routes the raw 16-bit phase adder output and lower 16 bits of the phase accumulator directly to the CMAC's sine and cosine inputs. This mode is essential for FFT butterfly computation, where the NCO output serves as twiddle factors rather than sinusoidal waveforms. The HSP45116AVC-52Z uses this feature to enable high-speed, deterministic FFT acceleration without external memory or control logic.
How does the HSP45116AVC-52Z handle output data formatting?
The HSP45116AVC-52Z provides flexible output formatting via the BINFMT pin and OUTMUX0/OUTMUX1 control lines. BINFMT selects between two's complement (default) and offset binary (unsigned) output formats by inverting RO19 and IO19 when low - critical for interfacing with DACs requiring unsigned input. OUTMUX0/1 selects among four output sources: CMAC high/low bits, accumulator outputs, or reserved states (Table 4). This allows the HSP45116AVC-52Z to adapt its 20-bit outputs to varying downstream data path requirements without external glue logic.
Is the HSP45116AVC-52Z still recommended for new designs?
No, the HSP45116AVC-52Z is marked "NOT RECOMMENDED FOR NEW DESIGNS" in the official Intersil FN4156 datasheet (Rev 4.00, May 2007), with no recommended replacement provided. While fully functional and supported for legacy program continuity, new designs should evaluate modern alternatives such as the AD9910 or integrated RF SoCs offering higher integration, lower power, and extended lifecycle. Aetrix Electronics maintains inventory and supply chain support for the HSP45116AVC-52Z to serve existing production and repair needs.
