Product details
Overview
HSP45102SC-40Z from Intersil is a 12-bit numerically controlled oscillator (NCO) with 32-bit frequency resolution, 40MHz maximum clock rate, and offset-binary 12-bit sine-wave output. It implements direct digital synthesis for precise frequency generation in communications systems, supporting BFSK/QPSK modulation via dual 32-bit frequency words and 90°-increment phase control through P0–P1 inputs.
For engineers reviewing the HSP45102SC-40Z datasheet, HSP45102SC-40Z pinout, HSP45102SC-40Z application, or HSP45102SC-40Z equivalent, key selection criteria include its 0.009Hz tuning resolution at 40MHz, -69dBc spurious performance, single-cycle frequency switching, and serial frequency loading architecture with pipeline-controlled timing.
Technical Context
The HSP45102SC-40Z integrates a 64-bit bidirectional shift register for serial frequency word loading, selectable MSB/LSB-first shifting, and dual 32-bit word selection via SEL_L/M. Its phase accumulator advances using integer arithmetic per Equation 2 (fOUT = fCLK × N / 232), with 13-bit phase angle computation feeding a Sine ROM.
Phase modulation is implemented by adding encoded P0–P1 bits to the top two bits of the 13-bit phase accumulator output, enabling 0°/90°/180°/270° shifts mapped directly to QPSK I/Q data paths. Output is delivered as offset-binary 12-bit data (OUT0–OUT11), compatible with standard DAC interfaces without sign-extension logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Clock Frequency | 40MHz - Enables output frequency synthesis up to ~10MHz with full 32-bit resolution and <0.009Hz step size. |
| Frequency Resolution | 0.009Hz at 40MHz - Achieved via 32-bit tuning word; supports fine-grained channel spacing in narrowband radios. |
| Spurious Free Dynamic Range | <-69dBc - Ensures clean spectral purity critical for PSK demodulation and low-error-rate communication links. |
| Output Format | 12-bit offset binary (OUT0=LSB) - Simplifies interface to 12-bit DACs (e.g., HI5731) without external level-shifting or biasing. |
| Phase Modulation | P0–P1 inputs enable 0°/90°/180°/270° shifts - Directly supports QPSK symbol mapping without external XOR logic or lookup tables. |
| Frequency Switching Latency | 1 clock cycle + 6-cycle pipeline delay - Allows rapid hop-settling in frequency-hopping spread spectrum (FHSS) systems. |
| Supply Voltage | +4.75V to +5.25V - Compatible with standard 5V TTL/CMOS logic rails and industrial-grade power supplies. |
Pinout & Package
Package: 28-lead SOIC (300 mil), Pb-free (RoHS compliant), M28.3 footprint (17.70–18.10 mm × 7.40–7.60 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | +5V rail connection; requires local 0.1µF decoupling per datasheet layout guidelines. |
| GND | Ground reference | Dual ground pins (pins 8, 15) reduce noise coupling between analog and digital sections. |
| CLK | Master system clock input | CMOS-level 40MHz clock; timing-critical path governing all internal pipeline stages. |
| SCLK | Serial shift clock | Rising-edge-triggered clock for frequency word loading; independent of CLK domain. |
| SD | Serial data input | MSB/LSB-first data stream into 64-bit frequency register; synchronized to SCLK when SFTEN low. |
| SFTEN | Shift enable (active low) | Gate controlling data entry into frequency register; must be held low during full 64-bit load sequence. |
| MSB/LSB | Shift direction control | Selects bit-order: high = MSB-first (data enters at FRCTRL63); low = LSB-first (enters at FRCTRL0). |
| SEL_L/M | Frequency word select | High = use FRCTRL0–31; low = use FRCTRL32–63; enables dual-frequency hopping without reprogramming. |
| TXFR | Transfer enable (active low) | Latches selected 32-bit word into phase accumulator input register on next CLK edge after 4-cycle pipeline delay. |
| LOAD | Phase accumulator reset | Zeroes accumulator feedback path after 5-cycle pipeline delay; used for deterministic phase initialization. |
| ENPHAC | Phase accumulator enable | Active-low gate; halts phase advancement when high, preserving current phase angle for hold modes. |
| P0, P1 | Phase modulation inputs | Encoded 2-bit control for 0°/90°/180°/270° phase offsets; active after 4-clock pipeline delay. |
| OUT0–OUT11 | 12-bit sine amplitude output | Offset-binary format (0x001–0xFFF centered at 0x800); OUT0 = LSB, OUT11 = MSB; drives DAC directly. |
Key Features
| Feature | Design Value |
|---|---|
| 32-bit frequency control resolution | Enables sub-Hz frequency steps at 40MHz clock, eliminating need for external PLL multipliers in precision signal sources. |
| Serial frequency loading interface | Reduces PCB routing complexity vs parallel bus; supports daisy-chaining multiple NCOs using shared SCLK/SD lines. |
| QPSK/BFSK modulation support | Integrated P0–P1 phase encoding and dual-word selection eliminate external modulator ICs in digital radio transceivers. |
| Offset-binary output format | Eliminates need for external DAC biasing circuitry or digital offset compensation in 12-bit DAC interfacing. |
| Static CMOS process | Permits zero-power standby (ICCSB ≤ 500µA) and glitch-free operation during clock gating or frequency hold modes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar numerically controlled oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9833BRMZ-REEL | 10-bit output, 25MHz max clock, SPI interface, no phase modulation pins | Lacks P0–P1 phase control and dual-word selection; limited to basic DDS without native QPSK support | Choose AD9833BRMZ-REEL only if 10-bit resolution and absence of phase modulation are acceptable for non-PSK applications. |
| MAX2748ETL+ | Integrated VCO+PLL, 2.4GHz RF output, no digital modulation interface | Generates RF directly but lacks programmable baseband modulation; not a drop-in replacement for DDS functions | Choose MAX2748ETL+ only when RF output at GHz frequencies is required and digital baseband synthesis is unnecessary. |
Compared with AD9833BRMZ-REEL and MAX2748ETL+, the HSP45102SC-40Z uniquely delivers 12-bit resolution, 40MHz clocking, and hardware-accelerated QPSK modulation in a single SOIC package-enabling higher spectral purity and lower system latency than either alternative in digital radio baseband designs.

FAQ
What is the maximum clock frequency supported by the HSP45102SC-40Z?
The HSP45102SC-40Z supports a maximum clock frequency of 40MHz, as confirmed by AC Electrical Specifications on page 7 of FN2810 Rev 9.00. At this rate, it achieves 0.009Hz tuning resolution and maintains <-69dBc spurious performance. Exceeding 40MHz violates absolute timing margins and may cause metastability in the 6-cycle internal pipeline.
Does the HSP45102SC-40Z support QPSK modulation natively?
Yes, the HSP45102SC-40Z supports QPSK modulation natively via its P0 and P1 phase modulation inputs, which encode 0°, 90°, 180°, or 270° phase shifts per Table 1 in the datasheet. This allows direct connection to symbol encoders without external phase-shifting circuitry, making the HSP45102SC-40Z ideal for digital radio transceivers.
What output data format does the HSP45102SC-40Z use, and why does it matter?
The HSP45102SC-40Z uses offset-binary output format across OUT0–OUT11, where 0x001 represents minimum amplitude and 0xFFF maximum, centered at 0x800. This eliminates the need for external DC biasing or digital offset correction when interfacing with standard 12-bit DACs like the HI5731, simplifying analog front-end design and reducing component count.
How many frequency control words can the HSP45102SC-40Z store and switch between?
The HSP45102SC-40Z stores two independent 32-bit frequency control words in its 64-bit shift register and switches between them using the SEL_L/M pin. When SEL_L/M is high, the least significant 32 bits (FRCTRL0–31) drive the phase accumulator; when low, the most significant 32 bits (FRCTRL32–63) are selected-enabling rapid frequency hopping in one clock cycle.
Is the HSP45102SC-40Z RoHS compliant, and what does the "Z" suffix indicate?
Yes, the "Z" suffix in HSP45102SC-40Z denotes Pb-free plus anneal construction per Intersil's RoHS compliance program: 100% matte tin termination, Pb-free molding compound, and compatibility with both SnPb and lead-free reflow profiles. This is explicitly stated in the Ordering Information table on page 1 of FN2810 Rev 9.00.
