Product details
Overview
HSP45106JC-33Z from Intersil is a 16-bit numerically controlled oscillator (NCO) designed for direct digital synthesis and quadrature signal generation in frequency-agile communication systems. It delivers simultaneous 16-bit sine and cosine outputs at up to 33MHz clock rate, with 32-bit frequency resolution (<0.008Hz at 33MHz), 16-bit phase control (<0.006° resolution), and >90dBc spurious-free dynamic range. It supports 8-level PSK modulation via discrete MOD(2:0) inputs and operates across 0°C to +70°C.
For engineers reviewing the HSP45106JC-33Z datasheet, HSP45106JC-33Z pinout, HSP45106JC-33Z application, or HSP45106JC-33Z equivalent, key selection criteria include its 84-lead PLCC package, parallel/serial output flexibility, two's complement or offset binary encoding, real-time phase/frequency agility, and compatibility with DAC interfaces in spread spectrum, PSK modem, and precision signal generation designs.
Technical Context
The HSP45106JC-33Z implements a two-stage architecture: a Phase/Frequency Control Section (PFCS) generating a 28-bit instantaneous phase word from 32-bit center/offset frequency and 16-bit phase offset registers, followed by a Sine/Cosine Section performing 20-bit-address ROM lookup to produce 16-bit quadrature outputs. Its PFCS includes a 32-bit phase accumulator, timer accumulator with TICO carry output, and discrete modulation logic synchronized to CLK.
Control is executed via an 16-bit microprocessor bus (C[15:0]) with A[2:0] address decoding, active-low CS/WR, and dedicated enable lines (ENCFREG, ENOFREG, ENPOREG, ENPHAC) that register on CLK rising edges. Output format (two's complement/offset binary) and interface mode (parallel/serial) are selected dynamically via BINFMT and PAR/SER pins, both registered on CLK.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Clock Frequency | 33MHz - determines maximum sample rate for quadrature output generation and real-time frequency/phase update speed. |
| Frequency Resolution | 32-bit word - enables <0.008Hz tuning step at 33MHz, critical for narrowband frequency-hopping and precise DDS applications. |
| Phase Resolution | 16-bit control - provides <0.006° phase step resolution, supporting high-fidelity 8PSK and coherent phase switching. |
| Output Format Options | Two's complement or offset binary - simplifies direct interfacing with common DACs without external level-shifting circuitry. |
| SFDR | >90dBc - ensures minimal spectral contamination in sensitive RF and communications signal chains. |
| Output Interface | Parallel (SIN/COS[15:0]) or serial (MSB-first on SIN15/COS15, LSB-first on SIN0/COS0) - offers layout and timing flexibility for system integration. |
| Supply Voltage | +4.75V to +5.25V - compatible with standard 5V logic and mixed-signal systems requiring tight regulation. |
Pinout & Package
Package: 84-lead Plastic Leaded Chip Carrier (PLCC), RoHS-compliant Pb-free finish (e3 termination), 0°C to +70°C operating range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | +5V power supply | Primary power rail for all internal logic and analog sections; requires local decoupling per high-speed NCO operation. |
| GND | Ground reference | Digital and analog ground return; multiple GND pins support low-impedance return paths for noise-sensitive quadrature outputs. |
| C[15:0] | 16-bit bidirectional control data bus | Loads configuration data into input registers (center/offset frequency, phase, timer); LSB-aligned (C0 = LSB). |
| A[2:0] | Address select for C[15:0] destination | Selects among seven 16-bit input registers (e.g., A[2:0]=000 → LSB Center Freq); decoded per Table 1 in datasheet. |
| CS, WR | Chip select and write enable | Active-low synchronous interface controls register loading; WR rising edge clocks data when CS is low. |
| CLK | Main system clock input | Drives all internal registers and accumulators; rising edge synchronizes ENxREG signals and updates PFCS state. |
| ENCFREG / ENOFREG / ENPOREG / ENPHAC | Register enable controls | Active-low, CLK-registered enables for downloading data from input registers to PFCS control registers (e.g., ENCFREG → Center Freq Register). |
| MOD[2:0], PMSEL | 8PSK modulation interface | Three-pin discrete interface for 0°–315° phase shifts; PMSEL selects between register-loaded or MOD-driven phase offset. |
| PAR/SER, BINFMT | Output configuration | CLK-registered mode selects: PAR/SER = high → parallel output; BINFMT = low → two's complement, high → offset binary. |
| OES, OEC | Output enable for sine/cosine buses | Active-low three-state control; allows shared bus usage or output disabling during configuration sequences. |
| SIN[15:0], COS[15:0] | 16-bit quadrature digital outputs | Simultaneous sine/cosine amplitude values; in serial mode, SIN15/COS15 = MSB-first, SIN0/COS0 = LSB-first streams. |
| DACSTRB | DAC strobe output | Active-low pulse indicating first bit of new serial word is valid; essential for synchronizing external DAC sampling in serial mode. |
Key Features
| Feature | Design Value |
|---|---|
| 32-bit frequency control | Enables sub-Hz frequency agility at 33MHz clock, supporting precise channel spacing in frequency-hopped spread spectrum systems. |
| 16-bit phase control with MOD[2:0] interface | Allows real-time 8PSK modulation without processor intervention-critical for low-latency BPSK/QPSK/8PSK modem implementations. |
| Configurable output encoding and interface | Eliminates need for external format conversion logic when interfacing with TI, ADI, or Maxim DACs supporting either two's complement or offset binary inputs. |
| Test mode with phase accumulator readout | Permits verification of internal phase state via SIN/COS pins while bypassing ROM lookup-valuable for calibration and debug of DDS loop stability. |
| Timer accumulator with TICO output | Generates programmable periodic interrupts (e.g., for frame sync or DAC update triggers) independent of main NCO output timing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar numerically controlled oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9854ASTZ | Integrated 300MHz DDS with on-chip 12-bit DAC, 48-bit frequency tuning, and SPI interface; requires external reconstruction filter. | Better suited for wideband RF synthesis (>100MHz) but lacks discrete 8PSK modulation pins and PLCC packaging. | Choose AD9854ASTZ when higher output frequency, integrated DAC, or SPI simplicity outweighs need for hardware PSK modulation and legacy PLCC footprint. |
| MAX2748ETL+ | 3.3V CMOS NCO with 24-bit tuning, 16-bit outputs, and I²C interface; smaller 40-pin TQFN package, no MOD[2:0] pins. | Targets battery-powered portable radios; lacks phase accumulator readout mode and timer accumulator with TICO output. | Choose MAX2748ETL+ for space-constrained, low-power designs where 3.3V operation and I²C control are prioritized over 5V compatibility and advanced timing features. |
Compared with AD9854ASTZ and MAX2748ETL+, the HSP45106JC-33Z uniquely combines 5V operation, 84-pin PLCC packaging, dedicated hardware PSK modulation pins, phase accumulator visibility, and timer-based interrupt generation-making it optimal for legacy industrial and defense systems requiring field-upgradeable, deterministic NCO behavior.

FAQ
What is the maximum operating clock frequency supported by the HSP45106JC-33Z?
The HSP45106JC-33Z is rated for a maximum clock frequency of 33MHz, as indicated by the "-33" suffix in its part number. This defines the upper limit for both the internal phase accumulator update rate and the sample rate of its 16-bit sine and cosine outputs. Operation above this frequency is not guaranteed and may result in timing violations or degraded SFDR performance.
Does the HSP45106JC-33Z support both parallel and serial output modes?
Yes, the HSP45106JC-33Z supports both parallel and serial output configurations. The PAR/SER pin selects the mode: when high, 16-bit sine and cosine data appear simultaneously on SIN[15:0] and COS[15:0]; when low, data is shifted out serially with MSB-first on SIN15/COS15 and LSB-first on SIN0/COS0, synchronized by DACSTRB.
How does the HSP45106JC-33Z implement 8-level PSK modulation?
The HSP45106JC-33Z implements 8-level PSK using three discrete MOD[2:0] inputs and the PMSEL pin. When PMSEL is low, MOD[2:0] directly set the three most significant bits of the phase offset register, producing eight distinct phase shifts (0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°), while the lower 13 bits are zeroed-enabling hardware-accelerated symbol mapping without processor involvement.
What is the purpose of the TEST pin on the HSP45106JC-33Z?
The TEST pin on the HSP45106JC-33Z enables diagnostic access to the internal 28-bit phase accumulator output. When asserted high (with PAR/SER also high), the most significant bits of the phase accumulator are routed to SIN[15:0] and COS[15:4], bypassing the Sine/Cosine ROM lookup. This allows real-time verification of phase progression during system bring-up or calibration.
Is the HSP45106JC-33Z RoHS compliant?
Yes, the HSP45106JC-33Z is RoHS compliant. The "Z" suffix denotes Intersil's Pb-free plastic packaging, featuring 100% matte tin (e3) termination finish, compatible with both SnPb and lead-free soldering processes, and meeting IPC/JEDEC J-STD-020 reflow requirements.
