Product details
Overview
LMH0002MA/NOPB from Texas Instruments is a 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 - used in broadcast video routing, HD/SD digital video transmission, and DVB-ASI interfaces.
For engineers reviewing the LMH0002MA/NOPB datasheet, LMH0002MA/NOPB pinout, LMH0002MA/NOPB application, or LMH0002MA/NOPB equivalent, key selection criteria include SMPTE compliance mode (259M vs. 292M), output voltage swing tuning (750 Ω / 590 Ω RREF), AC-coupled 75Ω coaxial drive capability, and SOIC-8 thermal performance (θJA = 160°C/W).
Technical Context
The LMH0002MA/NOPB implements a current-mode differential output stage optimized for 75Ω coaxial cable driving up to 1.485 Gbps, with dual-slew-rate control via the SD/HD pin to meet either SMPTE 259M (slower, ~400–800 ps rise/fall) or SMPTE 292M (faster, ~120–220 ps rise/fall) timing requirements.
Its self-biased differential input accepts DC- or AC-coupled signals within 100–2000 mVP−P swing and 1.6 V + VSDI/2 common-mode range; output amplitude is set by an external RREF resistor (750 Ω for 750–850 mVP−P, 590 Ω for 900–1100 mVP−P), and power consumption is 45–49 mA at 3.3 V in SD mode.
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 links. |
| Output Swing | 750–850 mVP−P (RREF = 750 Ω) or 900–1100 mVP−P (RREF = 590 Ω) into 75Ω load - enables precise amplitude tuning for cable loss compensation. |
| Rise/Fall Time | 120–220 ps (SD/HD = 0, SMPTE 292M) or 400–800 ps (SD/HD = 1, SMPTE 259M) - programmable edge speed ensures standard compliance without external filtering. |
| Additive Jitter | 26 psP-P at 1.485 Gbps - low jitter preserves eye opening in multi-hop video distribution systems. |
| Supply Current | 45–49 mA at 3.3 V (SD mode); 38–43 mA (HD mode) - enables low-power HD-SDI infrastructure design. |
| Operating Temp | −40°C to +85°C - qualified for industrial broadcast equipment and outside-plant enclosures. |
| Package | 8-pin SOIC (D package) - surface-mount compatible with standard reflow profiles and proven thermal resistance (θJA = 160°C/W). |
Pinout & Package
LMH0002MA/NOPB is housed in an 8-pin SOIC (D package), 1.75 mm max height, RoHS-compliant, with exposed pad not present. Pin 3 (VEE) and Pin 5 (VCC) provide ground and 3.3 V supply; Pins 1 & 2 (SDI/SDI) form the differential input; Pins 7 & 8 (SDO/SDO) deliver complementary differential outputs; Pin 4 (RREF) sets output amplitude; Pin 6 (SD/HD) selects slew rate.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SDI | Differential true data input - accepts self-biased AC/DC-coupled signals up to 2000 mVP−P. |
| 2 | SDI | Differential complement data input - forms matched pair with Pin 1 for noise rejection. |
| 3 | VEE | Negative supply (ground reference) - must be low-impedance for stable biasing and jitter control. |
| 4 | RREF | Output amplitude control - resistor to VCC sets driver current and output swing (750 Ω → 750–850 mVP−P). |
| 5 | VCC | Positive supply (3.3 V ±5%) - requires local 0.1 µF bypass capacitor near Pin 5 for high-frequency stability. |
| 6 | SD/HD | Slew rate select - logic low enables SMPTE 292M-fast mode (120–220 ps), high enables SMPTE 259M-slow mode (400–800 ps). |
| 7 | SDO | Differential complement output - delivers inverted signal into 75Ω coaxial cable with controlled return loss ≥15 dB. |
| 8 | SDO | Differential true output - delivers non-inverted signal; paired with Pin 7 for balanced transmission. |
Key Features
| Feature | Design Value |
|---|---|
| SMPTE 292M/259M Compliance | Hardware-selectable slew rate ensures guaranteed conformance to both HD-SDI and SD-SDI electrical standards without firmware or configuration. |
| Adjustable Output Amplitude | Single external RREF resistor (750 Ω or 590 Ω) tunes output swing across two calibrated ranges - simplifies system-level gain matching and cable loss compensation. |
| Differential Input Stage | Self-biased internal termination eliminates need for external bias networks - supports direct connection to FPGA LVDS outputs or AC-coupled sources. |
| 75Ω Differential Output | Current-mode driver delivers matched, low-return-loss (≥15 dB) differential signals directly into Belden 8281/1694A coax - no external transformers or baluns required. |
| Single 3.3V Supply | Eliminates need for dual-rail supplies or level shifters - reduces BOM count and PCB area in space-constrained broadcast modules. |

FAQ
What is the maximum data rate supported by the LMH0002MA/NOPB?
The LMH0002MA/NOPB supports data rates up to 1.485 Gbps, fully compliant with SMPTE 292M HD-SDI standards. This maximum rate is validated across the specified operating temperature range (0°C to +70°C) and supply voltage (3.3 V ±5%). The LMH0002MA/NOPB maintains signal fidelity at this rate with measured additive jitter of 26 psP-P and output rise/fall times of 120–220 ps in fast-slew mode.
How does the SD/HD pin affect LMH0002MA/NOPB operation?
The SD/HD pin on the LMH0002MA/NOPB selects output slew rate: logic low configures fast edges (120–220 ps) for SMPTE 292M HD-SDI compliance, while logic high enables slower edges (400–800 ps) for SMPTE 259M SD-SDI and DVB-ASI at 270 Mbps. This hardware-controlled mode eliminates software overhead and guarantees timing alignment per standard - a core functional feature of the LMH0002MA/NOPB.
Can the LMH0002MA/NOPB drive 75Ω coaxial cable directly without external components?
Yes, the LMH0002MA/NOPB drives 75Ω coaxial cable directly via its integrated current-mode differential outputs (Pins 7 and 8). It meets SMPTE return loss specifications (≥15 dB) when laid out per TI's reference design, requiring only a single RREF resistor (750 Ω or 590 Ω) and local VCC bypassing. No transformers, baluns, or series resistors are needed - a key integration advantage of the LMH0002MA/NOPB.
What is the purpose of the RREF pin on the LMH0002MA/NOPB?
The RREF pin on the LMH0002MA/NOPB sets output voltage swing by connecting an external resistor to VCC: 750 Ω yields 750–850 mVP−P, and 590 Ω yields 900–1100 mVP−P into 75Ω. This resistor directly controls driver current and enables precise amplitude calibration for varying cable loss - a critical tuning parameter implemented with zero active components in the LMH0002MA/NOPB signal path.
Is the LMH0002MA/NOPB pin-compatible with legacy Gennum drivers?
Yes, the LMH0002MA/NOPB is form-fit-function compatible with the Gennum GS1528 and GS1528A, sharing identical SOIC-8 packaging, pin numbering, and electrical behavior. TI explicitly documents this replacement path, confirming that existing PCB layouts and schematics using GS1528/GS1528A can adopt the LMH0002MA/NOPB without modification - a verified interoperability feature of the LMH0002MA/NOPB.
