Product details

Overview

HMC7150LP3DETR from Analog Devices (formerly Hittite Microwave) is a broadband electro-absorption modulated laser (EML) driver IC supporting 28.3 Gbps data rates, delivering 13 dB gain, ±7 ps group delay variation, 0.27 ps additive jitter, and up to 2.2 V_p-p output swing - deployed in 100GbE LR4/ER4 optical transceivers.

For engineers reviewing the HMC7150LP3DETR datasheet, HMC7150LP3DETR pinout, HMC7150LP3DETR application, or HMC7150LP3DETR equivalent, key selection criteria include supply voltage range (3.3–6 V), adjustable output amplitude (1.2–2.3 V_p-p), AC-coupled 50 Ω I/O, and LP3D 3×3 mm leadless package compatibility with CFP/CFP2 pluggable modules.

Technical Context

The HMC7150LP3DETR integrates a high-speed current-mode logic (CML)-compatible input stage and a broadband differential output stage optimized for EML biasing and modulation. It operates across 3.3 V to 6 V supply rails, enabling scalable power dissipation (0.12 W at 1.5 V_p-p, 0.50 W at 2.3 V_p-p) while maintaining sub-picosecond jitter performance.

Its output amplitude and cross-point are independently controlled via dedicated DC bias pins (VAMP and VCROSS), and both input and output ports are internally 50 Ω matched with AC coupling - eliminating external matching components in standard optical module layouts.

VCROSS	Cross-Point Control	Analog voltage input (0.5–1.2 V) adjusting output differential offset to optimize extinction ratio

Key Features

Feature	Design Value
Scalable Power Dissipation	0.12 W at 1.5 V_p-p output, 0.50 W at 2.3 V_p-p - reduces thermal load in dense CFP2/CFP4 modules

Equivalent & Alternatives

The following parts are listed as comparable options for similar EML driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX3736AETE+	Lower max data rate (14 Gbps), fixed 2.0 V_p-p output, no cross-point control	Targeted at 10G/40G SFP+/QSFP modules, not suitable for 100G LR4/ER4	Select only for cost-sensitive 10G designs where 28 Gbps capability is unnecessary
HMC988LP3E	Higher gain (18 dB), wider bandwidth (DC–26 GHz), but no amplitude/cross-point adjustment pins	Used in RF test equipment and microwave links; lacks EML-specific bias control features	Prefer when ultra-wideband analog gain is primary requirement, not optical modulation control

Compared with MAX3736AETE+ and HMC988LP3E, the HMC7150LP3DETR uniquely combines 28.3 Gbps operation, analog-adjustable amplitude and cross-point, and LP3D packaging - making it the only option qualified for production 100G CFP2/CFP4 EML driver applications requiring both performance and configurability.

FAQ

What supply voltage range does the HMC7150LP3DETR support?

The HMC7150LP3DETR operates from 3.3 V to 6 V DC supply. At 3.3 V, it delivers 1.5 V_p-p output with 0.12 W power dissipation; at 6 V, it achieves 2.3 V_p-p output with 0.50 W dissipation. Both rails require local ceramic decoupling per VCC pin to ensure broadband stability across its 28 Gbps bandwidth.

How is output amplitude adjusted on the HMC7150LP3DETR?

Output amplitude on the HMC7150LP3DETR is set via the VAMP pin, which accepts a DC control voltage from 0.5 V to 1.2 V to linearly scale differential output swing from 1.2 V_p-p to 2.3 V_p-p. This allows precise matching to the V_π of different EMLs without external resistive dividers or amplifiers - a feature confirmed in the Hittite HMC7150LP3DE datasheet revision dated October 2014.

Does the HMC7150LP3DETR require external AC coupling capacitors?

No, the HMC7150LP3DETR features integrated AC coupling on both input (IN+, IN−) and output (OUT+, OUT−) ports. Its 50 Ω matched I/O interfaces are designed for direct connection to CML/LVPECL sources and EML loads without external DC blocking capacitors - reducing bill-of-materials and PCB area in space-constrained optical modules.

What is the thermal pad configuration for the HMC7150LP3DETR LP3D package?

The HMC7150LP3DETR uses a 3×3 mm LP3D package with an exposed thermal pad centered on the bottom side. This pad must be soldered to a solid copper thermal plane on the PCB, connected to at least six GND pins (GND1–GND6) to achieve specified junction-to-board thermal resistance and sustain continuous 0.50 W operation at 6 V supply.

Can the HMC7150LP3DETR drive both EA and EML devices?

The HMC7150LP3DETR is specifically characterized and optimized for electro-absorption modulated lasers (EMLs), not generic electro-absorption (EA) modulators. Its output voltage range (up to 2.2 V_p-p), cross-point control, and drive strength align with industry-standard EML V_π and bias requirements - as validated in Hittite's application notes for 100GBASE-LR4/ER4 systems.
