Product details
Overview
LMH0002TMAX from Texas Instruments is an SMPTE 292M/259M-compliant serial digital cable driver IC with differential input, 75Ω differential output, selectable slew rate (SD/HD pin), adjustable output amplitude via RREF resistor, and single 3.3V supply operation. It supports data rates up to 1.485 Gbps and operates across −40°C to +85°C for industrial video routing applications.
For engineers reviewing the LMH0002TMAX datasheet, LMH0002TMAX pinout, LMH0002TMAX application, or LMH0002TMAX equivalent, this page delivers verified electrical specs, SOIC-8 package details, SMPTE compliance context, thermal performance (θJA = 160°C/W), and real-world substitution guidance for broadcast infrastructure design.
Technical Context
The LMH0002TMAX implements a current-mode differential output stage with programmable amplitude control via external RREF (750Ω or 590Ω) and dual-slew-rate selection through the SD/HD pin-low for SMPTE 292M (faster 120–220 ps rise/fall), high for SMPTE 259M (slower 400–800 ps). Its self-biased differential input accepts AC- or DC-coupled signals within 1.6 V to VCC–VSDI/2 common-mode range.
It operates exclusively from a 3.3V ±5% supply, drawing 38–49 mA depending on SD/HD state, with typical power consumption of 149 mW in HD mode. Output return loss meets ≥15 dB from 5 MHz to 1.5 GHz on compliant board layouts, and additive jitter is specified at 26 psP-P @ 1.485 Gbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 1.485 Gbps - enables SMPTE 292M HD-SDI transmission without signal degradation. |
| Output Swing | 750–850 mVP–P (RREF = 750Ω) or 900–1100 mVP–P (RREF = 590Ω) into 75Ω - sets precise cable drive level per system impedance matching. |
| Rise/Fall Time | 120–220 ps (SD/HD = 0) or 400–800 ps (SD/HD = 1) - ensures compliance with SMPTE 292M or 259M timing masks respectively. |
| Additive Jitter | 26 psP-P @ 1.485 Gbps - maintains bit-error-rate integrity in long-reach HD-SDI links. |
| Supply Current | 38–49 mA - determines thermal load and PCB power delivery requirements for continuous HD operation. |
| Operating Temp | −40°C to +85°C - qualifies for industrial-grade video equipment deployed in uncontrolled environments. |
| Package | 8-pin SOIC (D package) - standard surface-mount footprint compatible with automated assembly and legacy layout reuse. |
Pinout & Package
LMH0002TMAX is housed in an 8-pin SOIC package (JEDEC MS-012, variation AA), 3.91 mm × 4.90 mm body size, 1.75 mm max height, RoHS-compliant, lead finish Sn, MSL Level-1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SDI | Differential true data input - accepts self-biased AC/DC-coupled serial video data. |
| 2 | SDI | Differential complement data input - forms balanced pair with Pin 1 for noise rejection. |
| 3 | VEE | Negative supply (ground reference) - must be low-impedance plane connection for signal integrity. |
| 4 | RREF | Output amplitude control node - connects external resistor to VCC to set output swing (750Ω or 590Ω). |
| 5 | VCC | +3.3V supply input - requires local 0.1 µF ceramic decoupling adjacent to pin. |
| 6 | SD/HD | Slew rate select input - logic low enables SMPTE 292M fast edge; high enables SMPTE 259M slow edge. |
| 7 | SDO | Differential complement data output - drives 75Ω coaxial cable with current-mode output stage. |
| 8 | SDO | Differential true data output - completes 75Ω differential output pair with Pin 7 for EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| SMPTE 292M / 259M compliance | Guaranteed via dual-slew-rate control and output return loss ≥15 dB - eliminates need for external equalization in broadcast-standard links. |
| Adjustable output amplitude | Set by single external RREF resistor (750Ω or 590Ω) - enables precise calibration to cable loss and receiver sensitivity without redesign. |
| Differential input architecture | Self-biased inputs accept AC- or DC-coupled signals - simplifies interface to FPGA serializers, ADCs, or reclockers without external biasing networks. |
| Single 3.3V supply operation | Eliminates need for dual-rail supplies - reduces BOM count and layout complexity in space-constrained video modules. |
| Industrial temperature range | −40°C to +85°C operation - supports deployment in outdoor enclosures, broadcast trucks, and industrial vision systems. |

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 |
|---|---|---|---|
| LMH0002MA/NOPB | Same silicon, commercial temp range (0°C to +70°C); identical pinout and electrical specs. | Restricted to indoor, climate-controlled environments like studio racks or lab test gear. | Select LMH0002MA/NOPB only when ambient temperature remains within 0–70°C and industrial qualification is unnecessary. |
| GS1528A | Gennum part replaced by LMH0002MA; not form-fit-function compatible with LMH0002TMAX's industrial temp grade. | Lacks −40°C to +85°C rating; requires thermal derating or heatsinking outside commercial range. | LMH0002TMAX provides guaranteed industrial operation where GS1528A cannot be qualified without additional validation. |
Compared with LMH0002MA/NOPB, LMH0002TMAX adds guaranteed −40°C to +85°C operation without electrical trade-offs; compared with GS1528A, it delivers drop-in replacement capability only for commercial variants-not for industrial deployments requiring extended temperature reliability.

FAQ
What is the operating temperature range of the LMH0002TMAX?
The LMH0002TMAX is rated for industrial operation from −40°C to +85°C, verified per its Recommended Operating Conditions table. This range is confirmed in the TI SNLS215E datasheet and distinguishes it from the commercial-grade LMH0002MA/NOPB (0°C to +70°C). The LMH0002TMAX maintains full electrical performance-including 1.485 Gbps data rate and 26 psP-P jitter-across this entire span.
Does the LMH0002TMAX support both SMPTE 259M and SMPTE 292M standards?
Yes, the LMH0002TMAX supports both standards via its SD/HD pin: logic low configures faster rise/fall times (120–220 ps) for SMPTE 292M HD-SDI compliance, while logic high selects slower edges (400–800 ps) for SMPTE 259M SD-SDI. This dual-mode capability is explicitly documented in the Features and Application Information sections of the SNLS215E datasheet for the LMH0002TMAX.
What package type and pin count does the LMH0002TMAX use?
The LMH0002TMAX uses an 8-pin SOIC package (JEDEC MS-012, variation AA), designated as "D" in TI's packaging nomenclature. This is confirmed in the PACKAGE OPTION ADDENDUM and Mechanical Data sections of the official documentation. The LMH0002TMAX shares this exact footprint with LMH0002MA/NOPB and LMH0002MAX/NOPB, enabling direct PCB compatibility across temperature grades.
How is output amplitude controlled on the LMH0002TMAX?
Output amplitude on the LMH0002TMAX is controlled by an external resistor (RREF) connected between Pin 4 (RREF) and Pin 5 (VCC). A 750Ω resistor yields 750–850 mVP–P; a 590Ω resistor yields 900–1100 mVP–P, both into 75Ω loads. This method is detailed in the DC Electrical Characteristics table and APPLICATION INFORMATION section of the LMH0002TMAX datasheet.
Is the LMH0002TMAX pin-compatible with Gennum GS1528A or GS1578A devices?
No-the LMH0002TMAX is not pin-compatible with GS1528A or GS1578A. According to TI's Application Information, only the LMH0002MA is form-fit-function compatible with GS1528/GS1528A, and only the LMH0002SQ (16-pin WQFN) matches GS1578A. The LMH0002TMAX uses the same SOIC-8 package as LMH0002MA but lacks documented pin-to-pin equivalence with Gennum parts.
