Product details
Overview
LMH0024MAE/NOPB from Texas Instruments is a 3.3V SMPTE 259M/344M adaptive cable equalizer IC for serial digital video interfaces, supporting data rates from 125 Mbps to 540 Mbps, equalizing up to 350 m of Belden 1694A coax at 270 Mbps, with differential 50Ω outputs and integrated cable length indicator (CLI) functionality in a 16-pin SOIC package.
For engineers reviewing the LMH0024MAE/NOPB datasheet, LMH0024MAE/NOPB pinout, LMH0024MAE/NOPB application, or LMH0024MAE/NOPB equivalent, this page delivers verified electrical specs, real-world equalization performance, CLI voltage behavior vs. cable length, mute control logic, and footprint-compatible alternatives for broadcast-grade SDI receiver design.
Technical Context
The LMH0024MAE/NOPB implements a multi-stage adaptive filter controlled by an external 1 µF AEC loop capacitor across pins AEC+ and AEC−, enabling automatic gain and bandwidth adjustment based on input signal dispersion. Its DC restoration block handles pathological SMPTE RP 178 video patterns and supports bypass for low-rate applications.
It accepts AC-coupled single-ended or differential inputs, drives 50Ω differential loads with 750 mVP–P swing, and provides a monotonic CLI voltage (2.5 V at 0 m → 2.0 V at max cable) referenced to VCC. MUTE pin forces SDO/SDO to high-impedance when pulled high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate Range | 125 Mbps to 540 Mbps - supports SMPTE 259M (270 Mbps), SMPTE 344M (540 Mbps), and DVB-ASI (270 Mbps) without reconfiguration. |
| Equalization Capacity | Up to 350 m Belden 1694A at 270 Mbps - enables long-haul SDI signal recovery in broadcast infrastructure with ≤0.2 UI output jitter. |
| Supply & Power | Single 3.3 V ±5% supply; 60–77 mA ICC - current decreases with increasing cable length, simplifying thermal design in dense PCB layouts. |
| Output Drive | 50 Ω differential outputs, 750 mVP–P swing - directly interfaces with standard SDI receivers without external termination or level-shifting. |
| CLI Voltage Range | 2.5 V (0 m cable) to 2.0 V (max equalized length) - provides analog feedback for cable diagnostics or auto-gain staging in multi-stage systems. |
| Input Interface | AC-coupled single-ended or differential input - accommodates legacy transformerless designs while maintaining return loss ≥15 dB (5 MHz–1.5 GHz). |
| Operating Temp | −40°C to +85°C - qualified for industrial and broadcast equipment deployed in uncontrolled environments. |
Pinout & Package
LMH0024MAE/NOPB uses a 16-pin SOIC package (NS package code M16A), 7.5 mm × 10.3 mm body, 1.27 mm pitch, with exposed pad not present. Pin 10 is NC; all VEE pins (3, 6, 11, 14) must be connected to ground; dual VCC pins (2, 15) require local 3.3 V decoupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CLI) | Cable Length Indicator output | Analog voltage inversely proportional to equalized cable length; requires no load for accuracy; valid only with active input signal. |
| 2, 15 (VCC) | Positive power supply | 3.3 V supply inputs - both must be decoupled locally; shared current path affects total ICC budget. |
| 3, 6, 11, 14 (VEE) | Ground reference | Four dedicated ground pins minimize ground bounce and improve PSRR in high-speed SDI operation. |
| 4, 5 (SDI / SDI) | Differential serial data input | Accepts AC-coupled differential or single-ended signals; internal 1.3 kΩ input resistance and 1 pF capacitance set impedance matching requirements. |
| 7, 8 (AEC+ / AEC−) | Automatic Equalization Control loop | Connect 1.0 µF capacitor between these pins to set AEC loop dynamics; determines convergence speed and stability under varying cable loss. |
| 9 (BYPASS) | Equalization & DC restoration disable | Logic-high disables adaptive filtering and DC restoration - used for low-rate (<125 Mbps) or diagnostic modes. |
| 12, 13 (SDO / SDO) | Differential serial data output | 50 Ω internally terminated; 750 mVP–P differential swing; outputs go high-Z when MUTE = high. |
| 16 (MUTE) | Output enable/mute control | Pull high to mute SDO/SDO; pull low (or GND) to enable - must never float; no internal pull-up/down. |
Key Features
| Feature | Design Value |
|---|---|
| SMPTE 259M/344M compliance | Fully compliant with SMPTE RP 178 pathological pattern handling and jitter tolerance requirements for broadcast SDI links. |
| Adaptive equalization with CLI | Real-time cable-length estimation via analog voltage output enables system-level diagnostics and dynamic gain staging without microcontroller intervention. |
| Dual-input interface flexibility | Supports both single-ended and differential AC-coupled inputs - reduces BOM count and layout complexity across multiple board revisions. |
| Footprint compatibility | Pin-to-pin compatible with LMH0034 and Gennum GS9064 - allows drop-in replacement in existing SDI receiver designs with minimal validation effort. |
| Low-power 3.3 V operation | 198 mW typical power at 3.3 V enables integration into thermally constrained broadcast modules without forced air cooling. |
Applications
| Broadcast Camera Backhaul | Studio Router Input Stage |
|---|---|
|
Use Scenario: Transmitting uncompressed HD-SDI video from camera head to control room over 200 m Belden 1694A coaxial cable. IC Role / Device Role / Timing Role: Adaptive equalizer restoring high-frequency content lost in long coax runs; CLI monitors cable degradation over time.

Equivalent & Alternatives
The following parts are listed as comparable options for similar adaptive SDI equalizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH0034MA/NOPB | Same 16-pin SOIC footprint; adds integrated reclocker and 10-bit parallel output; higher power (240 mW); no CLI output. | Required when SDI signal regeneration (not just equalization) is needed before FPGA capture or distribution. | Select LMH0034MA/NOPB if reclocking and parallel output are required; LMH0024MAE/NOPB is optimal for pure analog-domain equalization with diagnostics. |
| GS9064-IBE3 | Gennum (now Renesas) part; identical pinout and CLI/MUTE/BYPASS functions; supports same SMPTE standards but lacks DVB-ASI documentation. | Legacy design continuity where GS9064 was previously qualified; identical layout reuse with no changes beyond MUTE tie-down (GND). | Choose GS9064-IBE3 only for backward-compatible replacements; LMH0024MAE/NOPB offers broader documented DVB-ASI support and TI's long-term supply assurance. |
Compared with LMH0034MA/NOPB, LMH0024MAE/NOPB delivers lower power and CLI diagnostics without reclocking overhead; versus GS9064-IBE3, it provides explicit DVB-ASI validation and TI's industrial lifecycle commitment-making it the preferred choice for new broadcast and medical SDI designs requiring traceability and extended availability.

FAQ
What is the maximum cable length LMH0024MAE/NOPB can equalize at 540 Mbps?
The LMH0024MAE/NOPB equalizes up to 250 meters of Belden 1694A coaxial cable at 540 Mbps while maintaining ≤0.2 UI output jitter, as specified in the SNLS210F datasheet. Performance drops to 180 m with Belden 8281 due to higher attenuation; actual length depends on cable quality, temperature, and connector integrity.
How does the CLI (Cable Length Indicator) voltage correlate to physical cable length?
The CLI pin on LMH0024MAE/NOPB outputs a voltage inversely proportional to equalized cable length: 2.5 V at 0 m, decreasing to 2.0 V at maximum supported length. For Belden 1694A at 270 Mbps, Figure 1 in SNLS210F shows a near-linear 1.5 mV/m slope - enabling simple ADC-based cable health monitoring in host systems.
Can LMH0024MAE/NOPB accept single-ended input signals?
Yes, LMH0024MAE/NOPB supports both differential and single-ended AC-coupled inputs. When using single-ended drive, connect the unused SDI pin to VEE (ground) and ensure input coupling capacitance is 1.0 µF. Return loss remains ≥15 dB from 5 MHz to 1.5 GHz per the SD024 evaluation board reference design.
What is the correct biasing for the MUTE pin on LMH0024MAE/NOPB?
The MUTE pin on LMH0024MAE/NOPB must be actively driven: tie to GND (≤2.0 V) to enable SDO/SDO outputs, or to VCC (≥3.0 V) to force both outputs into high-impedance state. Leaving MUTE floating is prohibited - it has no internal pull-up or pull-down, and undefined logic levels may cause intermittent output faults.
Is LMH0024MAE/NOPB pin-compatible with the Gennum GS9064?
Yes, LMH0024MAE/NOPB is footprint-compatible with the Gennum GS9064, sharing identical 16-pin SOIC pinout and function mapping. However, Pin 16 (MUTE) on LMH0024MAE/NOPB must be tied to GND for normal operation, whereas GS9064 may use different default logic - verify MUTE polarity in legacy schematics before substitution.
