Product details
Overview
LMH0202MT/NOPB from Texas Instruments is a dual SMPTE 292M/259M serial digital cable driver IC designed for high-speed video and data transmission over 75Ω coaxial cable. It supports data rates up to 1.485 Gbps, delivers dual 75Ω differential outputs with adjustable amplitude (750–1100 mVP-P), and operates from a single 3.3V supply with 250–300 mW power consumption in SD/HD modes. It is used in broadcast video routing, DVB-ASI distribution, and digital video infrastructure.
For engineers reviewing the LMH0202MT/NOPB datasheet, LMH0202MT/NOPB pinout, LMH0202MT/NOPB application, or LMH0202MT/NOPB equivalent, key selection criteria include SMPTE 292M/259M compliance, dual-channel slew-rate control via SD/HD pins, RREF-based output swing adjustment, and TSSOP-16 packaging for space-constrained video interface designs.
Technical Context
The LMH0202MT/NOPB implements two independent current-mode cable drivers, each with selectable slew rate (via SD/HD1/SD/HD2) to meet either SMPTE 259M (slower rise/fall) or SMPTE 292M (faster rise/fall) timing requirements. Input common-mode voltage is self-biased at ~2.1 V with 3.3 V supply, enabling direct AC or DC coupling without external biasing networks.
Each channel features dual differential inputs (SDIX/SDIX) and dual differential outputs (SDOX/SDOX), supporting flexible routing - including single-input-to-dual-output configurations for DVB-ASI. Output return loss exceeds 15 dB (5 MHz–1.5 GHz) on proper PCB layout, 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 full HD/3G-SDI transmission compliant with SMPTE 292M and 344M standards. |
| Output Swing | 750–1100 mVP-P into 75Ω - set by external RREF resistors (590Ω or 750Ω), allowing precise amplitude tuning per channel. |
| Slew Rate Control | Digital SD/HD pin per channel - low = SMPTE 292M mode (400–560 ps rise/fall), high = SMPTE 259M mode (120–220 ps). |
| Supply Voltage | 3.3 V ±5% - single-supply operation simplifies power design and eliminates negative rail requirements. |
| Power Consumption | 76–98 mA ICC - scales with SD/HD configuration, enabling optimized thermal management in dense video systems. |
| Jitter Performance | 26 psP-P additive jitter @ 1.485 Gbps - ensures signal integrity margin for long-haul coaxial runs in broadcast environments. |
| Operating Temperature | 0°C to +70°C - commercial-grade rating suitable for studio equipment, encoders, and non-ruggedized video infrastructure. |
Pinout & Package
LMH0202MT/NOPB is housed in a 16-pin TSSOP (PW package), 4.4 mm × 5.0 mm body size, 1.2 mm max height, with exposed thermal pad. Pin pitch is 0.65 mm; lead finish is Sn (RoHS-compliant, green). The package supports standard reflow profiles (MSL Level-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Differential Serial Data Inputs | SDI1/SDI1 and SDI2/SDI2 accept true/complement LVDS-like signals; self-biased at ~2.1 V for simplified coupling. |
| 3, 7 | Negative Supply (Ground) | VEE1 and VEE2 are separate ground returns per channel - improves PSRR and reduces crosstalk between drivers. |
| 4, 8 | Output Amplitude Control | RREF1/RREF2 connect to VCC via precision resistor (590Ω or 750Ω) to set output swing; placement critical for stability. |
| 9, 13 | Positive Supply | VCC2 and VCC1 provide independent 3.3 V supply paths per channel - decoupling required near each pin. |
| 10, 14 | Slew Rate Select | SD/HD2/SD/HD1 are TTL-compatible control inputs - low = HD mode (fast edge), high = SD mode (slower edge). |
| 11, 12, 15, 16 | Differential Serial Data Outputs | SDO2/SDO2 and SDO1/SDO1 drive 75Ω coax; true/complement pairs enable transformerless or transformer-coupled termination. |
Key Features
| Feature | Design Value |
|---|---|
| Dual SMPTE-compliant drivers | Independent channels support simultaneous SD and HD video streams or redundant signal paths in broadcast routers. |
| Selectably compliant slew rates | Per-channel SD/HD control allows mixed-standard systems (e.g., legacy SD-SDI and modern 3G-SDI) on one board. |
| Adjustable output amplitude | Two RREF pins enable fine-tuned swing matching across channels or compensation for trace loss in multi-drop layouts. |
| Self-biased differential inputs | Eliminates need for external bias resistors or AC-coupling capacitors in many applications, reducing BOM count and board area. |
| Low-power 3.3V operation | Sub-100 mA supply current per channel enables integration into thermally constrained enclosures 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 |
|---|---|---|---|
| LMH0302MT/NOPB | Higher data rate (up to 2.97 Gbps), supports SMPTE 424M (6G-SDI); same pinout and RREF/SD-HD control scheme. | Required for 4K/UHD video transport; not backward-compatible with legacy SD/HD-only designs due to higher bandwidth demands. | Select LMH0302MT/NOPB only when upgrading to 6G-SDI infrastructure; LMH0202MT/NOPB remains optimal for cost-sensitive 3G-SDI deployments. |
| THS8200IPHP | Triple-channel SDI driver with integrated reclocker; requires external clock and consumes >400 mW; different pinout and no RREF-based amplitude control. | Used where jitter cleanup is mandatory (e.g., long-chain distribution); unsuitable for simple pass-through or amplitude-tuning applications. | Choose THS8200IPHP only if reclocking is needed; LMH0202MT/NOPB is preferred for minimal-latency, low-power, amplitude-adjustable driving. |
Compared with LMH0302MT/NOPB and THS8200IPHP, the LMH0202MT/NOPB provides the optimal balance of SMPTE 259M/292M compliance, dual-channel flexibility, and low-power 3.3V operation - making it the standard choice for mainstream HD-SDI routing, encoding, and camera interface designs where 6G-SDI or reclocking are unnecessary.

FAQ
What is the maximum supported data rate for LMH0202MT/NOPB?
The LMH0202MT/NOPB supports data rates up to 1.485 Gbps, fully compliant with SMPTE 292M (HD-SDI) and SMPTE 259M (SD-SDI) standards. This specification is validated across the full operating temperature range (0°C to +70°C) and confirmed in the official SNLS212C datasheet. The LMH0202MT/NOPB maintains signal integrity at this rate with ≤26 psP-P additive jitter and >15 dB output return loss on properly designed PCBs.
How do I configure LMH0202MT/NOPB for SMPTE 292M versus SMPTE 259M operation?
Configure LMH0202MT/NOPB for SMPTE 292M (HD-SDI) by pulling SD/HD1 and SD/HD2 pins low (≤0.8 V); for SMPTE 259M (SD-SDI), pull them high (≥2.4 V). Each pin controls its respective channel independently, enabling mixed-mode operation. The LMH0202MT/NOPB's output rise/fall times change accordingly: 400–560 ps in HD mode and 120–220 ps in SD mode, as verified in AC electrical characteristics tables.
What resistor values should I use on RREF1 and RREF2 for LMH0202MT/NOPB to achieve 800 mVP-P output swing?
To achieve 800 mVP-P output swing on LMH0202MT/NOPB, connect 750 Ω ±1% resistors between RREF1 and VCC1, and RREF2 and VCC2. This value is explicitly specified in the "DC Electrical Characteristics" table of the SNLS212C datasheet for nominal 800 mVP-P performance into 75 Ω. The LMH0202MT/NOPB's output swing scales linearly with RREF value, so 590 Ω yields ~1000 mVP-P.
Does LMH0202MT/NOPB require external biasing for its differential inputs?
No, LMH0202MT/NOPB does not require external biasing for its differential inputs. The SDI1/SDI1 and SDI2/SDI2 inputs are self-biased at approximately 2.1 V when VCC = 3.3 V, enabling direct AC or DC coupling without additional resistors. This feature simplifies schematic design and reduces component count - a key advantage confirmed in the "INPUT INTERFACING" section of the LMH0202MT/NOPB datasheet.
Is LMH0202MT/NOPB pin-compatible with any other TI serial digital drivers?
LMH0202MT/NOPB shares the same 16-pin TSSOP (PW) package and pinout with LMH0302MT/NOPB, enabling drop-in replacement in many layouts when upgrading to 6G-SDI. However, LMH0302MT/NOPB operates at higher bandwidth (up to 2.97 Gbps) and may require updated layout validation. The LMH0202MT/NOPB datasheet confirms identical pin functions and placement - but system-level validation of signal integrity is recommended before substitution.
