Product details
Overview
LMH0202MTX 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 typical power consumption of 250–300 mW in SD/HD modes. It is used in broadcast-grade video routing, DVB-ASI distribution, and digital video infrastructure.
For engineers reviewing the LMH0202MTX datasheet, LMH0202MTX pinout, LMH0202MTX application, or LMH0202MTX 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 package compatibility with high-frequency PCB layout requirements for 1.5 GHz signal integrity.
Technical Context
The LMH0202MTX 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 masks. Input stage is self-biased differential, accepting AC- or DC-coupled signals with common-mode range of 1.6 V + VSDI/2.
Output amplitude is set per channel by external resistors (RREF1/RREF2) tied between RREF pins and VCC, enabling precise 75Ω single-ended swing tuning (750–1100 mVP-P). Return loss exceeds 15 dB from 5 MHz to 1.5 GHz on optimized 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 - supports full SMPTE 292M HD-SDI and SMPTE 344M operation. |
| Output Swing | 750–1100 mVP-P into 75Ω - adjustable per channel via RREF resistor value (590Ω or 750Ω). |
| Slew Control | Dual SD/HD pins - low = SMPTE 292M-compliant fast edges (400–560 ps); high = SMPTE 259M-compliant slower edges (120–220 ps). |
| Supply | Single 3.3V ±5% - eliminates need for dual-rail supplies; compatible with standard logic domain. |
| Power Consumption | 76–98 mA ICC - scales with SD/HD mode selection; enables thermal management in dense video boards. |
| Jitter Performance | 26 psP-P additive jitter @ 1.485 Gbps - meets SMPTE 292M eye diagram mask requirements. |
| Return Loss | ≥15 dB from 5 MHz to 1.5 GHz - ensures minimal signal reflection on properly terminated 75Ω traces/cables. |
Pinout & Package
LMH0202MTX is housed in a 16-pin TSSOP (PW package), 4.4 mm × 5.0 mm body, 1.2 mm max height, with 0.65 mm pitch. Pin 1 index located at top-left corner; exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SDI1 / SDI1 | Differential input pair (Channel 1) | Accepts AC- or DC-coupled serial video/data; self-biased at ~2.1 V with 3.3 V supply. |
| RREF1 | Output amplitude reference (Channel 1) | Resistor to VCC sets single-ended output swing (750Ω → 800 mVP-P; 590Ω → 1000 mVP-P). |
| SD/HD1 | Slew rate select (Channel 1) | Low = SMPTE 292M fast edges; high = SMPTE 259M slow edges - configures rise/fall time directly. |
| SDO1 / SDO1 | Differential output pair (Channel 1) | Current-mode 75Ω outputs; require AC coupling and 75Ω termination at receiver end. |
| VCC1 / VCC2 | Positive supply rails | Separate VCC pins per channel reduce crosstalk; must be decoupled locally with 0.1 µF + 4.7 µF. |
| VEE1 / VEE2 | Ground reference | Common ground for both channels; requires low-inductance connection to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent SMPTE-compliant drivers | Enables simultaneous HD-SDI and SD-SDI routing on one IC without inter-channel skew or crosstalk penalties. |
| Per-channel slew rate selection | Eliminates need for external edge-rate control circuitry; simplifies design for multi-standard systems (e.g., broadcast switchers). |
| Adjustable output amplitude via RREF | Allows fine-tuning to match cable loss or receiver sensitivity without redesigning output network. |
| Self-biased differential inputs | Supports direct connection to FPGA/ASIC serializers or legacy video sources without level-shifting or biasing networks. |
| Optimized for 75Ω coaxial interface | Meets return loss and jitter specs on standard Belden 1694A/8281 cables up to 100 m at 1.485 Gbps. |

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 | Higher 2.97 Gbps data rate; supports SMPTE 424M; same TSSOP-16 package and pinout. | Required for 3G-SDI (1080p60 progressive) systems; not backward-compatible with LMH0202MTX's lower-power SD/HD mode logic. | Select LMH0302MTX only when 3G-SDI bandwidth and SMPTE 424M compliance are mandatory. |
| THS8200IPHP | Triple-channel, integrated reclocker; requires external clock; higher power (450 mW); HTSSOP-48 package. | Used where jitter cleanup is needed before retransmission; adds latency and complexity versus LMH0202MTX's zero-latency buffer-only function. | Choose THS8200IPHP only if input jitter exceeds SMPTE limits and reclocking is required - otherwise LMH0202MTX is simpler and lower-cost. |
Compared with LMH0202MTX, LMH0302MTX extends bandwidth to 3G-SDI but increases power and cost, while THS8200IPHP adds reclocking capability at the expense of pin count, layout complexity, and latency - making LMH0202MTX optimal for pure retransmission in SD/HD-SDI infrastructure.

FAQ
What is the maximum supported data rate for LMH0202MTX?
The LMH0202MTX supports data rates up to 1.485 Gbps, fully compliant with SMPTE 292M (HD-SDI) and SMPTE 259M (SD-SDI) standards. At this rate, it achieves 26 psP-P additive jitter and meets SMPTE 292M eye diagram requirements. Operation at 270 Mbps (SMPTE 259M) yields lower jitter (18 psP-P) and relaxed slew requirements.
How does the SD/HD pin control output slew rate in LMH0202MTX?
The SD/HD pin on LMH0202MTX selects output rise/fall time per channel: logic low configures faster edges (400–560 ps) for SMPTE 292M compliance, while logic high selects slower edges (120–220 ps) for SMPTE 259M. Both SD/HD1 and SD/HD2 operate independently, allowing mixed-mode operation - e.g., Channel 1 in HD mode, Channel 2 in SD mode - within a single LMH0202MTX.
Can LMH0202MTX accept single-ended inputs?
Yes, LMH0202MTX accepts single-ended inputs via external AC coupling and proper biasing, though its native interface is differential. The inputs are self-biased (~2.1 V with 3.3 V supply), so single-ended signals must remain within the common-mode range (1.6 V + VSDI/2). For best noise immunity and jitter performance, differential input is strongly recommended - especially for 1.485 Gbps operation.
What resistor values are recommended for RREF1 and RREF2 on LMH0202MTX?
TI specifies two standard RREF resistor values for LMH0202MTX: 750 Ω ±1% for 750–850 mVP-P output swing (SMPTE 259M/292M nominal), and 590 Ω ±1% for 900–1100 mVP-P swing (higher drive margin for long cables or lossy connectors). Resistors must be placed adjacent to the RREF pin, with ground-plane copper removed beneath to minimize parasitic capacitance.
Is LMH0202MTX pin-compatible with any other TI cable drivers?
LMH0202MTX shares the same TSSOP-16 (PW) package and pinout with LMH0302MTX, enabling drop-in replacement in many layouts when upgrading from HD-SDI to 3G-SDI. However, LMH0302MTX requires different supply sequencing and has higher ICC; firmware or system-level validation is required before substitution. No other TI cable driver offers identical pin-for-pin compatibility with LMH0202MTX.
