Product details
Overview
LMH0366SQE/NOPB from Texas Instruments is a 3 Gbps SMPTE ST 424/ST 292/ST 259-C compliant HD/SD SDI reclocker with integrated 64×64 eye monitor, supporting data rates from 125 Mbps to 2.97 Gbps, consuming 100 mW typical power, and operating on a single 2.5 V supply for broadcast video routing and distribution amplifier applications.
For engineers reviewing the LMH0366SQE/NOPB datasheet, LMH0366SQE/NOPB pinout, LMH0366SQE/NOPB application, or LMH0366SQE/NOPB equivalent, key selection considerations include input FR4 equalization (0–60″), dual LVDS reclocked outputs with programmable de-emphasis (up to 40″ trace loss), referenceless or 27 MHz external clock operation, industrial temperature range (−40°C to +85°C), and SPI/pin-mode configuration flexibility.
Technical Context
The LMH0366SQE/NOPB implements a CDR-based reclocking architecture with adaptive PLL loop bandwidth (220 kHz at 270 Mbps, 1.7 MHz at 2.97 Gbps) and automatic rate detection across six standard video rates. It integrates an FR4-input equalizer with programmable boost and supports both pin-strapped and SPI-configurable operation modes.
Its dual LVDS outputs support independent selection of reclocked data, recovered clock, or bypassed data, with per-output control of swing (400–800 mVP-P), offset (0.8–1.2 V), de-emphasis (0–7 dB), polarity inversion, and power-down - all accessible via SPI registers or hardware pins depending on mode.
Key Specifications

Pinout & Package
LMH0366SQE/NOPB uses a 24-pin WQFN package (RTW0024A) with exposed die attach pad (DAP = VEE). Pin functions differ between pin mode (SPI_EN = GND) and SPI mode (SPI_EN = VCC); dual-mode pins include RATE0/RATE1, BYPASS/MOSI, MUTE/SCK, SCO_EN/SS, and VEE/MISO.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 2,3 SDI/SDI | Differential serial data input | 100 Ω internally terminated, rail-to-rail common-mode, accepts DC-coupled SDI signals from equalizers like LMH0394 |
| 13,14 SDO1/SDO1 | Differential serial output 1 | LVDS output configurable as reclocked data, recovered clock, or bypassed data; supports programmable swing/de-emphasis |
| 16,17 SDO0/SDO0 | Differential serial output 0 | LVDS output configurable as reclocked data or bypassed data; independently controllable amplitude and common-mode voltage |
| 7 SPI_EN | Mode select control | High = SPI register access mode; Low = pin-strapped mode; determines functionality of five dual-mode I/O pins |
| 11 LOCK_DETECT | PLL lock status indicator | Active-high open-drain output; asserts only when PLL is locked to valid input signal - invalid during bypass or unlock |
| 15 VCC | Positive supply | 2.5 V ±5% main power rail; requires local decoupling per TI layout guidelines |
| DAP, 9,12,20,21 VEE | Ground / negative supply | Primary ground return path; exposed DAP must be soldered to PCB ground plane for thermal and electrical performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SDI reclocking applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH0384SQE/NOPB | Higher power (165 mW), supports 6G-SDI (5.94 Gbps), no integrated eye monitor, same 24-pin WQFN | Required for UHD/4K workflows; lacks diagnostic eye monitoring capability | Select when upgrading to 6G-SDI infrastructure; not drop-in due to higher current and missing eye monitor feature |
| GS2971-IBE3 | Multi-standard (SD/HD/3G/6G), integrated cable driver, 3.3 V supply, different pinout and SPI register map | Used in transceiver designs requiring bidirectional SDI signal conditioning | Choose for new designs needing combined reclock + drive functionality; requires PCB redesign and firmware adaptation |
Compared with LMH0366SQE/NOPB, LMH0384SQE/NOPB adds 6G-SDI support but removes eye monitoring and increases power, while GS2971-IBE3 integrates driver functionality at the cost of supply voltage compatibility and pin-level interoperability - making LMH0366SQE/NOPB optimal for dedicated, low-power, diagnostic-capable 3G-SDI reclocking.

FAQ
What video standards does the LMH0366SQE/NOPB support?
The LMH0366SQE/NOPB supports SMPTE ST 424 (3G-SDI), ST 292 (HD-SDI), and ST 259-C (SD-SDI), plus DVB-ASI at 270 Mbps and MADI at 125 Mbps. It operates at exact rates including 1.4835 Gbps, 1.485 Gbps, 2.967 Gbps, and 2.97 Gbps - all confirmed in the SNAS585D datasheet AC Electrical Characteristics table.
Does the LMH0366SQE/NOPB require an external crystal?
No, the LMH0366SQE/NOPB supports referenceless operation. An external 27 MHz crystal or clock on XTAL_IN is optional and only needed to distinguish between 1.485/1.4835 Gbps and 2.97/2.967 Gbps variants. In referenceless mode, XTAL_IN must be grounded per the datasheet Pin Descriptions section.
How does the eye monitor in the LMH0366SQE/NOPB function?
The LMH0366SQE/NOPB provides a 64 × 64 point real-time eye opening monitor accessible only in SPI mode. It analyzes the incoming SDI signal before equalization and is disabled during bypass mode. Data is read via SPI register reads - no external display interface is required, but host MCU firmware must implement the read sequence per Section 8.5.3 of SNAS585D.
Can the LMH0366SQE/NOPB operate with only one output enabled?
Yes, the LMH0366SQE/NOPB supports independent power-down of each LVDS output driver via SPI registers (0x11 bit 3 for SDO1_PD, bit 4 for SDO0_PD). With one output active and low-power settings, supply current drops to 40–55 mA - verified in the DC Electrical Characteristics table under "Normal operation, one output driver and low power settings".
What is the maximum FR4 trace length the LMH0366SQE/NOPB can equalize on input?
The LMH0366SQE/NOPB supports up to 60 inches of FR4 trace length on its differential input, as specified in the Features list and Functional Description section. For traces longer than 40″, register 0x11 bit 1 (EQ_BOOST_60) must be set to enable additional equalizer gain - a requirement explicitly stated in the Input FR4 Equalization subsection of the datasheet.
