Product details
Overview
HMC1034LP6GE from Analog Devices (formerly Hittite Microwave) is a wideband fractional-N PLL clock generator IC with integrated VCO, delivering differential clock outputs from 125 MHz to 3 GHz. It features a low-noise phase detector, Delta-Sigma modulator, 24-bit frequency resolution (3 Hz typical step), 78 fs RMS jitter (integer mode, 800 MHz), and -165 dBc/Hz phase noise floor - enabling high-precision timing in optical line cards and SERDES interfaces.
For engineers reviewing the HMC1034LP6GE datasheet, HMC1034LP6GE pinout, HMC1034LP6GE application, or HMC1034LP6GE equivalent, this device supports exact-frequency synthesis, SPI programmable amplitude control, built-in digital self-test, and meets G.8251/GR-253-CORE jitter compliance for telecom infrastructure design.
Technical Context
The HMC1034LP6GE implements a fractional-N PLL architecture with integrated RF VCO, supporting maximum phase detector rates of 100 MHz (fractional mode B) and 125 MHz (integer mode). Its Delta-Sigma modulator enables fine frequency resolution and suppresses fractional spurs, while the Exact Frequency Mode ensures near-zero output frequency error.
It integrates dual supply domains: 5 V for VCO core/buffer (VCC2), charge pump (VPPCP/VDDCP), and RF/PLL buffers (VCC1); and 3.3 V for analog prescaler (VCCHF), phase detector (VCCPD), reference (RVDD), digital (DVDD3V), and logic (AVDD). Output amplitude is digitally adjustable via 2-bit SPI-controlled gain settings (00–11).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 125 MHz to 3000 MHz - covers OTU4, 100G Ethernet, SONET STS-768, and 32G Fibre Channel reference clocks. |
| RMS Phase Jitter (Typ.) | 78 fs - measured at 800 MHz, 50 MHz ref, integer mode; enables <1e-15 BER in high-speed serial links. |
| Phase Noise Floor | <-165 dBc/Hz - ensures minimal close-in and broadband noise contribution to ADC sampling or SERDES CDR. |
| FOM (Fractional Mode) | -227 dBc/Hz - industry-leading figure of merit indicating optimal tradeoff between power and spectral purity. |
| Max PFD Rate | 100 MHz - permits wide loop bandwidths (>250 kHz) for fast lock time and effective jitter attenuation. |
| Frequency Resolution | 3 Hz typical - 24-bit fractional divider enables precise alignment to ITU-T line rates (e.g., 622.08 MHz, 156.25 MHz). |
| Output Amplitude Control | 4 settings (00–11), 300–1100 mVpp differential - allows optimization for 100 Ω termination across multiple PHY interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar clock generator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMK04832RHAR | Separate PLL + VCO architecture; dual-loop jitter cleaner; supports JESD204B SYSREF; no integrated VCO in same package. | Better suited for multi-device deterministic latency sync; higher power (≈350 mA); larger 7-mm QFN. | Select when deterministic delay, multi-channel skew control, or JESD204B support is required over single-chip integration. |
| AD9528BCPZ | 14-output clock distributor with integrated dual-loop PLL; lower max output (1.2 GHz); no on-chip VCO (requires external). | Optimized for FPGA/ASIC clock tree distribution; lacks wideband RF VCO; limited to ≤1.2 GHz outputs. | Select when distributing multiple synchronized clocks to heterogeneous logic, memory, and SerDes - not for direct RF clock synthesis. |
Compared with LMK04832RHAR and AD9528BCPZ, the HMC1034LP6GE delivers superior single-package integration (PLL + VCO + output buffer), wider frequency coverage (125–3000 MHz), and lower phase noise floor, making it optimal for compact, high-performance RF clocking where board space and jitter budget are critical.

FAQ
What is the maximum reference input frequency supported by the HMC1034LP6GE?
The HMC1034LP6GE supports a maximum reference input frequency of 350 MHz under AC-coupled conditions with 100 Ω external termination. This enables direct use of high-speed crystal oscillators or recovered line clocks without prescaling, preserving timing integrity in OTN and SyncE systems. The HMC1034LP6GE reference stage is optimized for both square and sinusoidal waveforms.
Does the HMC1034LP6GE require an external loop filter?
Yes, the HMC1034LP6GE requires an external passive loop filter connected between the CP pin and VTUNE pin. The recommended Type 1 or Type 2 filter values depend on target loop bandwidth (e.g., 250 kHz for jitter attenuation, 100 kHz for SyncE), and are specified in the Hittite PLL Operating Guide. No internal loop filter is integrated.
Can the HMC1034LP6GE generate exactly 622.08 MHz for SONET/SDH applications?
Yes, the HMC1034LP6GE supports exact-frequency synthesis via its Exact Frequency Mode and 24-bit fractional-N divider, enabling precise generation of 622.08 MHz (STS-192/STM-64 rate) with negligible frequency error. This eliminates manual N/R calculations and guarantees compliance with GR-253-CORE jitter masks.
What power supply voltages does the HMC1034LP6GE require?
The HMC1034LP6GE requires two voltage domains: 4.8–5.2 V for VPPCP, VDDCP, VCC1, and VCC2 (VCO and charge pump analog sections); and 3.0–3.5 V for AVDD, RVDD, DVDD3V, VCCHF, VCCPD, and VCCPS (digital, reference, and prescaler sections). Proper sequencing and decoupling per the datasheet are mandatory for stable operation.
Is there an evaluation platform available for the HMC1034LP6GE?
Yes, Hittite (now Analog Devices) offers the EVAL01-HMC1034LP6GE evaluation PCB and the EKIT01-HMC1034LP6GE evaluation kit, which includes USB interface hardware, cables, software, and schematics. These platforms enable rapid validation of loop filter design, jitter measurement, and SPI configuration of the HMC1034LP6GE in real-world timing applications.
