Product details

Overview

LMH0001SQX/NOPB from Texas Instruments is an SMPTE 259M/344M-compliant serial digital cable driver IC designed for high-speed video signal transmission over 75Ω coaxial lines. It operates at data rates up to 540 Mbps, delivers adjustable 750–1100 mV_P-P single-ended output swing into 75Ω, and draws 43 mA typical supply current from a single 3.3V supply. Used in broadcast-grade digital routers and distribution amplifiers.

For engineers reviewing the LMH0001SQX/NOPB datasheet, LMH0001SQX/NOPB pinout, LMH0001SQX/NOPB application, or LMH0001SQX/NOPB equivalent, key selection criteria include SMPTE compliance, differential input support, RREF-controlled amplitude tuning, industrial temperature range (−40°C to +85°C), and WQFN-16 thermal performance (θ_JA = 78.9°C/W).

Technical Context

The LMH0001SQX/NOPB implements a current-mode differential driver architecture with self-biased inputs enabling AC/DC coupling. Its output stage uses external RREF resistor feedback to set output voltage swing across 75Ω loads, supporting both SMPTE 259M (270 Mbps) and SMPTE 344M (540 Mbps) standards.

It features additive jitter of 18 ps_P-P at 270 Mbps, rise/fall times of 400–800 ps (20%–80%), and output return loss ≥20 dB from 5 MHz to 1.5 GHz on validated board layouts. Input common-mode voltage is fixed at ~2.1 V with VCC = 3.3 V, and ESD protection meets 5 kV HBM.

Key Specifications

Parameter	Value and Actual Design Meaning
Data Rate	Up to 540 Mbps - supports full SMPTE 344M and DVB-ASI at 270 Mbps without retiming.
Output Swing	750–1100 mV_P-P single-ended into 75Ω - set by RREF value (590Ω or 750Ω) for precise amplitude control.
Supply Current	43 mA typical - enables low-power operation in multi-channel broadcast infrastructure.
Jitter	18 ps_P-P additive jitter at 270 Mbps - ensures signal integrity in long-haul SDI links.
Operating Temp	−40°C to +85°C - qualified for industrial and broadcast equipment deployed in uncontrolled environments.
Package Thermal θ_JA	78.9°C/W - requires minimal heatsinking in compact WQFN-16 layout with exposed thermal pad soldered to PCB ground.

Pinout & Package

LMH0001SQX/NOPB is housed in a 16-pin WQFN package (RUM0016A) with 0.65 mm pitch, 4.0 × 4.0 mm body, and exposed thermal pad connected to VEE. The package requires soldering the DAP to PCB ground for thermal and mechanical reliability.

Pin/Terminal	Circuit Role	Design Meaning
SDI / SDI	Differential input pair	Accepts self-biased differential or single-ended signals; common-mode ~2.1 V at VCC = 3.3 V.
SDO / SDO	Differential output pair	Current-mode outputs drive 75Ω coax; true/complement outputs enable balanced transmission.
RREF	Amplitude control reference	Resistor between RREF and VCC sets output swing (750Ω → 800 mV_P-P; 590Ω → 1000 mV_P-P).
VCC	Positive supply	Single 3.3V ±5% rail powers entire driver; decoupling required near pin 9.
VEE	Negative supply / ground	Reference node for all signals and thermal pad; must be low-impedance connection to PCB ground plane.
NC (pins 5,6,7,8,10,13,14,15)	No-connect	Unused pins - must remain unconnected; no internal circuitry attached.

Key Features

Feature	Design Value
SMPTE 259M/344M compliance	Fully meets electrical and timing requirements for broadcast SDI infrastructure, including return loss ≥20 dB up to 1.5 GHz.
Adjustable output amplitude	Two standard RREF values (750Ω/590Ω) provide factory-tuned swing options without redesigning output network.
Differential input interface	Self-biased inputs eliminate need for external termination or biasing resistors in most AC-coupled applications.
Low additive jitter	18 ps_P-P at 270 Mbps preserves eye opening in cascaded routing systems with multiple drivers/receivers.
Industrial temperature rating	Validated operation from −40°C to +85°C ensures reliability in rack-mounted broadcast gear with limited airflow.

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial digital cable driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LMH0002SQ/NOPB	Pin-compatible variant with identical pinout and package but optimized for lower power (38 mA typ) and reduced jitter (15 ps_P-P).	Preferred where multi-channel density and thermal budget are constrained, e.g., dense video processing blades.	Select LMH0002SQ/NOPB when lower power and tighter jitter are prioritized over cost; same PCB layout applies.
GS9078A	Functionally similar SMPTE 259M/344M driver in 16-pin WQFN, but specifies 200 mV_P-P minimum input swing and lacks RREF-based amplitude tuning.	Used in legacy DVB-ASI-only systems where fixed-gain output suffices and external gain control is handled upstream.	Choose GS9078A only if existing designs already use it and RREF flexibility is not required; not drop-in for amplitude-critical SDI routing.

Compared with LMH0001SQX/NOPB, LMH0002SQ/NOPB offers lower jitter and power at identical pinout, while GS9078A provides fixed-gain operation without RREF tuning-making LMH0001SQX/NOPB optimal for applications requiring field-adjustable output levels in SMPTE-compliant infrastructure.

FAQ

What is the maximum data rate supported by the LMH0001SQX/NOPB?

The LMH0001SQX/NOPB supports data rates up to 540 Mbps, fully complying with SMPTE 344M and DVB-ASI standards. This enables reliable transmission of HD-SDI (1.485 Gbps) in dual-link mode or 3G-SDI (2.97 Gbps) using multiplexed clock recovery schemes. The LMH0001SQX/NOPB maintains specified jitter and return loss performance at this maximum rate when used with proper PCB layout and termination.

How does the RREF pin control output amplitude in the LMH0001SQX/NOPB?

The RREF pin on the LMH0001SQX/NOPB sets output voltage swing by connecting an external resistor between RREF and VCC. A 750Ω resistor yields 750–850 mV_P-P, while a 590Ω resistor increases swing to 900–1100 mV_P-P, both measured into 75Ω. This resistor must be placed adjacent to the RREF pin with minimized parasitic capacitance, as specified in the LMH0001SQX/NOPB datasheet.

Is the LMH0001SQX/NOPB compatible with single-ended input signals?

Yes, the LMH0001SQX/NOPB accepts single-ended inputs via either SDI or SDI pin, leveraging its self-biased input stage. DC-coupled inputs must stay within the common-mode range (1.6 V + V_SDI/2), and AC-coupled configurations require no external biasing. The LMH0001SQX/NOPB maintains full SMPTE 259M/344M compliance regardless of input configuration.

What is the thermal resistance (θ_JA) of the LMH0001SQX/NOPB in its WQFN package?

The LMH0001SQX/NOPB has a junction-to-ambient thermal resistance (θ_JA) of 78.9°C/W in its 16-pin WQFN (RUM0016A) package. This value assumes the exposed thermal pad is soldered to a solid PCB ground plane. Failure to connect the DAP reduces thermal performance significantly, risking junction temperature exceedance above 150°C under full-load conditions.

Does the LMH0001SQX/NOPB require external termination resistors on its outputs?

No, the LMH0001SQX/NOPB integrates 75Ω differential output impedance and is designed to drive 75Ω coaxial cables directly without external series or parallel termination. Its output return loss exceeds 20 dB from 5 MHz to 1.5 GHz on properly designed boards, satisfying SMPTE 259M/344M return loss requirements without added components.
