Product details
Overview
HMC910LC4BTR-R5 from Analog Devices (formerly Hittite Microwave) is a broadband analog time delay IC designed for high-speed signal alignment in RF and serial data paths. It delivers 0–70 ps continuously adjustable delay across DC–24 GHz, with linear VDC control, 10 MHz modulation bandwidth, and differential output swing adjustable from 170–760 mVp-p at 24 GHz - enabling precise clock/data synchronization in 32 Gbps transceivers.
For engineers reviewing the HMC910LC4BTR-R5 datasheet, HMC910LC4BTR-R5 pinout, HMC910LC4BTR-R5 application, or HMC910LC4BTR-R5 equivalent, key selection criteria include its 24 GHz bandwidth, temperature-compensated delay stability, single 3.3 V supply operation, 24-lead 4×4 mm ceramic SMT package, and enable-controlled power-down capability.
Technical Context
The HMC910LC4BTR-R5 implements a voltage-controlled analog delay line architecture with internal temperature compensation and bias circuitry to maintain delay accuracy over –40°C to +70°C. Its differential input accepts 100–2000 mVp-p signals, while the VAC pin adjusts output amplitude independently of delay setting.
All RF I/Os are internally 50 Ω terminated to Vcc, supporting direct connection to 50 Ω-to-Vcc systems or AC coupling via external blocking capacitors when interfacing with 50 Ω-to-ground or other DC-biased terminations. The ENB pin enables full device shutdown, reducing current draw to 15 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 24 GHz - supports full-rate operation up to 32 Gbps NRZ data without bandlimiting. |
| Adjustable Delay Range | 59–70.5 ps depending on frequency (62.5 ps typ @ 10 GHz, 70 ps typ @ 24 GHz) - enables sub-bit-period alignment in high-speed links. |
| Delay Control Linearity | Linearly monotonic vs. VDC (1.1–2.3 V) - simplifies closed-loop delay calibration with standard DACs. |
| Differential Output Swing | 170–760 mVp-p @ 24 GHz (adjustable via VAC 1.7–2.7 V) - matches receiver sensitivity requirements across process/voltage/temperature. |
| Supply & Power | +3.3 V ±9%, 400–550 mA typical - compatible with standard LDOs; thermal resistance 18.2 °C/W enables operation at 85 °C ambient with proper heatsinking. |
| Jitter Performance | 6 ps pp deterministic jitter, 0.3 ps rms additive random jitter @ 24 GHz - preserves signal integrity in low-jitter timing chains. |
| Enable Function | ENB pin disables device, dropping current to 15 mA - supports dynamic power gating in multi-channel systems. |
Pinout & Package
24-lead ceramic 4×4 mm surface-mount package (16 mm² footprint), alumina body with gold-over-nickel plating, MSL3 rated, bottom ground paddle requiring solder connection to PCB RF ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6, 18 | N/C | No internal connection; externally grounded per RF layout best practice to minimize parasitic coupling. |
| 2, 5, 14, 17 | GND | Signal ground pins - must connect to 0 V reference plane; ground paddle is mandatory for thermal and RF performance. |
| 3, 4 | INP, INN | Differential RF input pair - accepts 100–2000 mVp-p signals; internally 50 Ω terminated to Vcc. |
| 7, 10, 12, 13 | Vee | Supply ground - connects to 0 V; separate from signal GND but tied at system common point. |
| 8 | Vdc | Analog delay control voltage input (1.1–2.3 V) - linearly sets delay; 10 MHz modulation bandwidth supports real-time tuning. |
| 9 | ENB | Active-high enable - open or +3.3 V for normal operation; 0 V disables device and reduces current to 15 mA. |
| 11 | Vac | Output amplitude control (1.7–2.7 V) - independently scales differential output swing without affecting delay. |
| 15, 16 | QN, QP | Differential RF outputs - 50 Ω internally terminated to Vcc; directly drive 50 Ω-to-Vcc loads or require AC coupling for other terminations. |
| 19–24 | Vcc | +3.3 V power supply - six dedicated supply pins ensure low-impedance delivery and reduce supply noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| DC–24 GHz bandwidth | Enables use in millimeter-wave radar, 5G FR2, and optical interconnect timing without external equalization. |
| Temperature-compensated delay | –0.03 ps/°C sensitivity @ 20 GHz ensures <±1 ps drift over –40°C to +70°C operating range. |
| Independent delay & amplitude control | Vdc and Vac pins decouple timing alignment from signal level optimization - critical for adaptive link training. |
| Internal 50 Ω RF termination | Eliminates need for external resistors; simplifies layout and maintains impedance match across full bandwidth. |
| Low-jitter signal path | 6 ps pp deterministic jitter and 0.3 ps rms random jitter preserve eye opening in 24 GHz clock distribution. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar broadband analog time delay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC844LC4BTR-R5 | Same 24-lead 4×4 mm package, but fixed 40 ps delay (no VDC control); lower power (320 mA). | Suitable only for static delay compensation; lacks real-time tunability required for adaptive systems. | Select when delay value is invariant and jitter budget allows fixed solution. |
| ADRF6780ACPZ-R7 | Integrated IQ modulator with programmable delay (0–100 ps), but limited to 12 GHz max RF bandwidth and higher power (750 mA). | Targets modulation path delay, not standalone timing alignment; requires complex baseband interface. | Select only when delay function must coexist with modulation in same die; not drop-in for pure delay use cases. |
Compared with HMC910LC4BTR-R5, the HMC844LC4BTR-R5 offers lower cost and power for static delay needs but sacrifices tunability, while the ADRF6780ACPZ-R7 integrates delay into a broader signal chain function at the expense of bandwidth and design simplicity - making HMC910LC4BTR-R5 the optimal choice for dedicated, wideband, voltage-programmable delay.

FAQ
What is the maximum data rate supported by the HMC910LC4BTR-R5?
The HMC910LC4BTR-R5 supports up to 32 Gbps NRZ data transmission, verified using PRBS 223–1 patterns at 22.5 Gbps and confirmed operation at full 32 Gbps in serial data applications. Its DC–24 GHz bandwidth and 6 ps pp deterministic jitter ensure minimal eye closure at these rates, making HMC910LC4BTR-R5 suitable for PCIe Gen6, CEI-32G, and optical interconnect timing.
How does the HMC910LC4BTR-R5 handle temperature-induced delay drift?
The HMC910LC4BTR-R5 incorporates internal temperature compensation circuitry that limits delay drift to –0.03 ps/°C at 20 GHz. Over its full –40°C to +70°C operating range, this results in less than ±1.5 ps total variation - significantly tighter than uncompensated analog delay lines. This stability is critical for HMC910LC4BTR-R5 deployment in unheated outdoor RF equipment and high-density compute modules.
Can the HMC910LC4BTR-R5 be used with single-ended inputs?
Yes, the HMC910LC4BTR-R5 accepts both single-ended and differential inputs. Its input sensitivity supports 50–1000 mVp-p for single-ended signals and 100–2000 mVp-p for differential signals. Internally, all RF inputs are 50 Ω terminated to Vcc, so single-ended drive requires only one side of the INP/INN pair driven with proper DC biasing - no external termination needed for HMC910LC4BTR-R5 compatibility.
What is the purpose of the VAC pin on the HMC910LC4BTR-R5?
The VAC pin on the HMC910LC4BTR-R5 controls differential output voltage swing independently of delay setting, accepting 1.7–2.7 V to adjust output amplitude from 170–760 mVp-p at 24 GHz. This allows system designers to optimize signal level for downstream receiver sensitivity without altering timing alignment - a key advantage of HMC910LC4BTR-R5 over fixed-gain delay solutions.
Does the HMC910LC4BTR-R5 require external DC blocking capacitors?
External DC blocking capacitors are required only when interfacing HMC910LC4BTR-R5 outputs with systems terminated to 50 Ω to a DC voltage other than Vcc. Since all RF I/Os are internally 50 Ω terminated to Vcc, direct connection is valid for Vcc-referenced loads; otherwise, series capacitors must be added to prevent DC mismatch and potential damage - a design consideration explicitly documented for HMC910LC4BTR-R5 implementation.
