Product details
Overview
LMH0202MTX/NOPB from Texas Instruments is a dual SMPTE 292M/259M serial digital cable driver IC with two 75Ω differential outputs, selectable slew rates for SD/HD compliance, and adjustable output amplitude via external RREF resistors. It operates from a single 3.3V supply, delivers up to 1.485 Gbps data rate, and targets broadcast video routing and DVB-ASI transmission over coaxial cable.
For engineers reviewing the LMH0202MTX/NOPB datasheet, LMH0202MTX/NOPB pinout, LMH0202MTX/NOPB application, or LMH0202MTX/NOPB equivalent, key selection criteria include SMPTE 292M/259M compliance mode control (SD/HD pins), differential input common-mode range (1.6 V + VSDI/2), output swing adjustability (750–1100 mVP–P), and TSSOP-16 thermal performance (θJA = 125°C/W).
Technical Context
The LMH0202MTX/NOPB implements two independent current-mode drivers, each with configurable rise/fall time via dedicated SD/HD control inputs-low for SMPTE 292M (400–560 ps), high for SMPTE 259M (120–220 ps). Input stages are self-biased for DC- or AC-coupled differential signals, with common-mode voltage fixed at ~2.1 V under 3.3 V supply.
Output amplitude is set per channel by resistor networks between RREF1/RREF2 and VCC, enabling precise 75 Ω coaxial drive levels (e.g., 800 mVP–P at RREF = 750 Ω). Return loss meets ≥15 dB from 5 MHz to 1.5 GHz on validated board layouts, and additive jitter remains ≤26 psP–P at 1.485 Gbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 1.485 Gbps - supports full SMPTE 292M HD-SDI and SMPTE 344M operation. |
| Output Swing | 750–1100 mVP–P into 75 Ω - adjustable per channel via RREF1/RREF2 resistor values. |
| Slew Rate Control | Dual SD/HD pins - low = SMPTE 292M mode (fast edge), high = SMPTE 259M mode (slower edge). |
| Supply Voltage | 3.3 V ±5% - single-rail operation eliminates need for dual supplies or level shifters. |
| Power Consumption | 76–98 mA ICC - scales with SD/HD mode selection; ~300 mW in HD mode, ~250 mW in SD mode. |
| Input Common Mode | 1.6 V + VSDI/2 - self-biased differential inputs simplify interface with FPGA/ASIC serializers. |
| Additive Jitter | ≤26 psP–P at 1.485 Gbps - ensures signal integrity margin for multi-hop HD-SDI distribution. |
Pinout & Package
LMH0202MTX/NOPB uses a 16-pin TSSOP (PW package), 4.4 mm × 5.0 mm body, 0.65 mm pitch, 1.2 mm max height, RoHS-compliant "Green" finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Differential Data Inputs (SDI1, SDI1, SDI2, SDI2) | True/complement pairs accept AC- or DC-coupled SMPTE-compliant serial video/data streams. |
| 3, 7 | Negative Supply (VEE1, VEE2) | Ground reference for respective input/output channels; must be low-inductance connection. |
| 4, 8 | Output Amplitude Control (RREF1, RREF2) | Resistor-to-VCC sets output swing per channel; placement critical to minimize parasitic capacitance. |
| 9, 13 | Positive Supply (VCC2, VCC1) | 3.3 V power rails for output drivers; decoupling required near each pin. |
| 10, 14 | Slew Rate Select (SD/HD2, SD/HD1) | Logic-level control: low = SMPTE 292M timing, high = SMPTE 259M timing. |
| 11, 12, 15, 16 | Differential Outputs (SDO2, SDO2, SDO1, SDO1) | Current-mode 75 Ω outputs; require AC coupling and proper 75 Ω termination at receiver. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent SMPTE drivers | Enables simultaneous HD-SDI and SD-SDI routing or redundant signal paths without external multiplexing. |
| Selectably compliant slew rates | Eliminates need for separate SD/HD driver variants-single BOM item covers both broadcast standards. |
| Adjustable output amplitude per channel | Allows optimization for cable length, connector loss, or receiver sensitivity without redesigning PCB layout. |
| Self-biased differential inputs | Reduces external biasing components and simplifies interface with serializer ICs or FPGAs. |
| Single 3.3 V supply operation | Lowers system power architecture complexity and reduces bill-of-materials vs. dual-supply alternatives. |

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 |
|---|---|---|---|
| LMH0302MTX/NOPB | Higher 2.97 Gbps data rate; supports SMPTE 424M; identical pinout and RREF/SD-HD control scheme. | Required for 3G-SDI systems; not backward-compatible in HD-SDI-only designs due to higher power (380 mW) and tighter layout constraints. | Select LMH0302MTX/NOPB only when 3G-SDI bandwidth or SMPTE 424M compliance is mandatory. |
| THS8200IPHP | Triple-channel, integrated reclocker; requires external clock; no RREF-based amplitude control; different pinout and supply (1.8 V core + 3.3 V I/O). | Used where jitter cleanup is needed before retransmission; unsuitable for direct cable drive without additional buffering. | Choose THS8200IPHP when retiming and regeneration are required-not for simple cable driving. |
Compared with LMH0202MTX/NOPB, LMH0302MTX/NOPB extends bandwidth to 3G-SDI but increases power and layout sensitivity, while THS8200IPHP adds reclocking capability at the cost of pinout incompatibility and higher system complexity.

FAQ
What is the maximum supported data rate for LMH0202MTX/NOPB?
The LMH0202MTX/NOPB supports data rates up to 1.485 Gbps, fully compliant with SMPTE 292M (HD-SDI) and SMPTE 259M (SD-SDI) standards. This is confirmed in the AC Electrical Characteristics table of the SNLS212C datasheet, where DRSDI is specified at 1485 Mbps for all differential inputs. The device maintains ≤26 psP–P additive jitter at this rate, ensuring reliable signal integrity in broadcast-grade systems.
How does the SD/HD pin control slew rate in LMH0202MTX/NOPB?
In LMH0202MTX/NOPB, each SD/HD pin (pins 10 and 14) independently selects slew rate per channel: logic low configures faster rise/fall times (400–560 ps) for SMPTE 292M compliance, while logic high selects slower edges (120–220 ps) for SMPTE 259M. This is explicitly defined in Table 1 and the OUTPUT SLEW RATE CONTROL section of the SNLS212C datasheet, enabling mixed-format operation without external components.
Can LMH0202MTX/NOPB drive 75 Ω coaxial cable directly?
Yes, LMH0202MTX/NOPB is designed to drive 75 Ω coaxial cable directly-such as Belden 8281 or 1694A-without external line drivers or transformers. Its current-mode outputs deliver 750–1100 mVP–P into 75 Ω loads, and its output return loss meets ≥15 dB from 5 MHz to 1.5 GHz when used with proper board layout, as verified on the SD202 evaluation board per the datasheet.
What is the function of RREF1 and RREF2 pins on LMH0202MTX/NOPB?
RREF1 (pin 4) and RREF2 (pin 8) on LMH0202MTX/NOPB set output voltage swing per channel by connecting an external resistor to VCC. For example, a 750 Ω resistor yields 750–850 mVP–P, while a 590 Ω resistor yields 900–1100 mVP–P. The SNLS212C datasheet specifies these relationships in the DC Electrical Characteristics table and emphasizes placing RREF resistors close to their pins to minimize parasitic capacitance.
Is LMH0202MTX/NOPB compatible with DVB-ASI applications?
Yes, LMH0202MTX/NOPB is explicitly qualified for DVB-ASI applications. As shown in Figure 3 of the SNLS212C datasheet, its dual differential inputs can be externally routed to accept a single differential ASI input, producing two non-inverted outputs ideal for ASI fanout. Power consumption remains within 300 mW, and output jitter meets ETSI EN 300 429 requirements when configured per TI's recommended layout.
