Product details
Overview
LMH0002TMA/NOPB 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), and adjustable output amplitude via RREF resistor. It operates on a single 3.3V supply, supports data rates up to 1.485 Gbps, and targets HD/SD video transmission over coaxial cable in broadcast infrastructure.
For engineers reviewing the LMH0002TMA/NOPB datasheet, LMH0002TMA/NOPB pinout, LMH0002TMA/NOPB application, or LMH0002TMA/NOPB equivalent, key selection criteria include SMPTE compliance mode control, output swing tuning via RREF, thermal performance in industrial temperature range (−40°C to +85°C), and SOIC-8 package compatibility with legacy Gennum GS1528A replacement designs.
Technical Context
The LMH0002TMA/NOPB implements a current-mode differential output stage optimized for driving 75Ω coaxial cables (e.g., Belden 8281/1694A) at serial digital video rates. Its SD/HD pin selects between SMPTE 259M (slower rise/fall: 400–800 ps) and SMPTE 292M (faster: 120–220 ps) slew profiles, directly mapping to SD vs. HD video timing requirements.
Differential input accepts AC- or DC-coupled signals with self-biased common-mode voltage (~2.1 V at VCC = 3.3 V); output amplitude is set by external RREF (590 Ω for 1.0 VP–P, 750 Ω for 0.8 VP–P single-ended into 75 Ω), enabling precise signal integrity tuning across cable lengths and termination variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 1.485 Gbps - supports full SMPTE 292M HD-SDI and SMPTE 259M SD-SDI operation. |
| Output Swing | 750–850 mVP–P (RREF = 750 Ω) or 900–1100 mVP–P (RREF = 590 Ω) - enables compliance with cable loss budgets via resistor selection. |
| Rise/Fall Time | 120–220 ps (SD/HD = 0, SMPTE 292M) or 400–800 ps (SD/HD = 1, SMPTE 259M) - hardware-selectable edge control for standard-specific jitter management. |
| Additive Jitter | 26 psP–P @ 1.485 Gbps - ensures signal integrity margin for long-haul HD-SDI links. |
| Supply Voltage | 3.3 V ±5% - single-rail operation simplifies power design in video routing equipment. |
| Operating Temp | −40°C to +85°C - industrial-grade rating suitable for broadcast enclosures and outdoor camera backends. |
| Power Consumption | 49 mA typical in SD mode (125 mW), 43 mA in HD mode (149 mW) - low static power enables dense channel integration. |
Pinout & Package
LMH0002TMA/NOPB uses an 8-pin SOIC (D package) with exposed thermal pad not connected in this variant. Pin 3 (VEE) and Pin 5 (VCC) establish the 3.3 V supply rails; Pins 1 & 2 (SDI/SDI) form the differential input; Pins 7 & 8 (SDO/SDO) deliver the differential output; Pin 4 (RREF) sets output amplitude; Pin 6 (SD/HD) configures slew rate.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SDI | Differential true input - accepts AC/DC-coupled serial digital video with self-biased common-mode (~2.1 V). |
| 2 | SDI | Differential complement input - paired with Pin 1 for noise-rejecting signal reception. |
| 3 | VEE | Negative supply (ground reference) - must be low-impedance for stable output common-mode control. |
| 4 | RREF | Output amplitude control - resistor to VCC sets single-ended output swing (750 Ω → 0.8 VP–P). |
| 5 | VCC | Positive supply (3.3 V) - bypass capacitor required near pin for high-frequency stability. |
| 6 | SD/HD | Slew rate select - low = SMPTE 292M (fast edges), high = SMPTE 259M (slower edges). |
| 7 | SDO | Differential complement output - drives 75 Ω coax with current-mode architecture. |
| 8 | SDO | Differential true output - paired with Pin 7 for balanced HD/SD-SDI transmission. |
Key Features
| Feature | Design Value |
|---|---|
| SMPTE 292M/259M Compliance | Hardware-selectable slew rate ensures conformance to both HD and SD video standards without firmware or external logic. |
| Adjustable Output Amplitude | RREF pin enables precise 0.8–1.1 VP–P swing tuning to compensate for PCB trace loss and connector degradation. |
| Differential Input Architecture | Self-biased inputs accept both AC- and DC-coupled sources, eliminating level-shifting circuitry in router and switch designs. |
| Industrial Temperature Range | −40°C to +85°C operation supports deployment in uncontrolled broadcast environments and outdoor security camera housings. |
| Low Power HD Operation | 149 mW at 1.485 Gbps enables thermal management in multi-channel video distribution amplifiers without forced air cooling. |

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 SOIC-8 package and pinout; commercial temp range (0°C to +70°C) instead of industrial. | Restricted to climate-controlled studio environments; unsuitable for outdoor or industrial enclosures. | Select LMH0002MA/NOPB only when ambient operating temperature remains within 0–70°C and cost sensitivity outweighs thermal margin needs. |
| GS1528A | Legacy Gennum part; identical form-fit-function per TI documentation but obsolete with no active support or new shipments. | Limited to legacy repair or spare parts sourcing; no new design-in recommended due to discontinuation status. | LMH0002TMA/NOPB is the designated drop-in replacement; use GS1528A only for direct field replacement where LMH0002TMA/NOPB is unavailable. |
Compared with LMH0002MA/NOPB, the LMH0002TMA/NOPB provides extended temperature resilience critical for outdoor broadcast gear, while versus GS1528A it delivers active manufacturing support, RoHS compliance, and guaranteed long-term supply - making it the sole viable option for new industrial HD-SDI designs.

FAQ
What is the maximum data rate supported by the LMH0002TMA/NOPB?
The LMH0002TMA/NOPB supports data rates up to 1.485 Gbps, fully compliant with SMPTE 292M HD-SDI standards. This capability is verified across the industrial temperature range (−40°C to +85°C) and confirmed in the AC Electrical Characteristics table of the official SNLS215E datasheet. The LMH0002TMA/NOPB maintains additive jitter ≤26 psP–P at this rate, ensuring robust signal integrity for long-haul HD video links.
How does the SD/HD pin affect LMH0002TMA/NOPB operation?
The SD/HD pin on the LMH0002TMA/NOPB selects output slew rate: logic low configures faster rise/fall times (120–220 ps) for SMPTE 292M HD-SDI compliance, while logic high enables slower edges (400–800 ps) for SMPTE 259M SD-SDI. This hardware-controlled mode eliminates need for configuration registers or external timing logic. The LMH0002TMA/NOPB's SD/HD pin is TTL-compatible and draws only 3.7 µA, simplifying interface with FPGA or microcontroller GPIO.
What is the purpose of the RREF pin on the LMH0002TMA/NOPB?
The RREF pin on the LMH0002TMA/NOPB sets output voltage swing by connecting an external resistor to VCC. A 750 Ω resistor yields 750–850 mVP–P single-ended output; a 590 Ω resistor increases swing to 900–1100 mVP–P. This adjustment compensates for cable attenuation and ensures SMPTE-compliant eye diagrams. The LMH0002TMA/NOPB datasheet specifies tight tolerance requirements (1%) for RREF resistors to maintain amplitude accuracy across temperature.
Is the LMH0002TMA/NOPB pin-compatible with the Gennum GS1528A?
Yes, the LMH0002TMA/NOPB is form-fit-function compatible with the Gennum GS1528A per TI's official application note and replacement guidance. Both use identical 8-pin SOIC packaging, matching pin assignments (including SDI, SDO, RREF, and SD/HD), and share electrical specifications for SMPTE 259M/292M operation. The LMH0002TMA/NOPB replaces GS1528A in new designs with enhanced industrial temperature support and active supply chain assurance.
What package type and thermal characteristics does the LMH0002TMA/NOPB use?
The LMH0002TMA/NOPB uses an 8-pin SOIC (D package) with θJA = 160°C/W and θJC = 105°C/W. Unlike the WQFN variant, this SOIC version lacks an exposed thermal pad. Its industrial temperature rating (−40°C to +85°C) and 149 mW HD-mode power dissipation require standard PCB copper pour for thermal management. The LMH0002TMA/NOPB's package marking "L002T" distinguishes it from commercial-grade variants.
