Product details
Overview
DS30EA101SQX/NOPB from Texas Instruments is an adaptive cable equalizer IC designed for high-speed serial data recovery in video and data transmission systems. It supports data rates from 150 Mbps to 3.125 Gbps, provides up to ~50 dB equalization at 1.5 GHz, operates on a single 2.5V supply, and delivers 115 mW typical power consumption - enabling long-cable extension of SD/HD video over coaxial or 100Ω differential cables.
For engineers reviewing the DS30EA101SQX/NOPB datasheet, DS30EA101SQX/NOPB pinout, DS30EA101SQX/NOPB application, or DS30EA101SQX/NOPB equivalent, key selection criteria include its automatic equalization capability across variable cable loss, LVDS output compliance, industrial temperature range (–40°C to +85°C), and WQFN-16 package integration with exposed thermal pad.
Technical Context
The DS30EA101SQX/NOPB implements adaptive continuous-time linear equalization (CTLE) to compensate frequency-dependent attenuation in copper cables. Its gain adjustment dynamically tracks signal integrity degradation across cable lengths from 0 to >120 meters (RG59) or >50 meters (CAT6), without requiring external configuration or firmware.
It accepts both differential (100Ω) and single-ended (75Ω) inputs via AC coupling, features integrated LVDS outputs with internal 100Ω termination, and includes LOS detection with programmable EN control - allowing automatic output disable when no valid input is present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate Range | 150 Mbps to 3.125 Gbps - supports SD, HD, and high-speed serial data links including SMPTE and FPGA SerDes interfaces. |
| Cable Equalization | Up to ~50 dB @ 1.5 GHz - restores signal integrity over long coaxial (RG59) or twisted-pair (CAT6) runs without manual tuning. |
| Supply Voltage | 2.5 V ±5% - single-rail operation simplifies power design and reduces BOM count in space-constrained video systems. |
| Power Consumption | 115 mW typical - enables thermally constrained deployments in multi-channel surveillance encoders or compact DVRs. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and outdoor security camera back-end electronics and vehicle-mounted video recorders. |
| Output Interface | LVDS (100Ω internally terminated) - ensures compatibility with standard LVDS receivers without external termination resistors. |
| Input Flexibility | Differential or single-ended AC-coupled input - supports both 75Ω coaxial and 100Ω differential cable infrastructure. |
Pinout & Package
DS30EA101SQX/NOPB is housed in a 4 mm × 4 mm, 0.8 mm max height, 16-pin WQFN package (TI package code RUM0016A) with an exposed die attach pad (DAP) electrically connected to VEE for thermal and electrical grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 7, 8, 9, 12, DAP | VEE | Negative power supply (ground) - multiple ground pins and exposed pad ensure low-impedance return path for high-frequency signals and thermal dissipation. |
| 2, 3 | IN+, IN− | Differential data input - accepts AC-coupled LVDS, CML, or PECL signals; also supports single-ended input with proper termination. |
| 10, 11 | OUT−, OUT+ | LVDS differential output - internally terminated to 100Ω, DC-coupled compatible, compliant with ANSI/TIA/EIA-644. |
| 13, 16 | VCC | +2.5V power supply - dual VCC pins reduce supply noise and improve PSRR at high data rates. |
| 14 | EN | LVCMOS output enable - internal pulldown enables outputs by default; tied to LOS for automatic shutdown during signal loss. |
| 15 | LOS | Loss-of-signal indicator - open-drain LVCMOS output asserts high when no valid input signal is detected. |
| 5, 6 | DNC | Do not connect - floating pins; must remain unconnected per TI design guidelines to avoid parasitic coupling or ESD risk. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive CTLE architecture | Real-time gain adjustment compensates cable loss from 0 to 50 dB without external control or calibration. |
| Multi-cable support | Validated for both 75Ω coaxial (RG59) and 100Ω differential (CAT6) cables - eliminates need for separate equalizers per medium. |
| Integrated LOS + EN logic | Enables fail-safe output disable when signal disappears - critical for video systems requiring clean black-level transitions during cable disconnect. |
| Low-power LVDS interface | 115 mW typical consumption with 350 mV differential output swing - meets power budgets in multi-channel DVRs and edge AI cameras. |
| Industrial-grade reliability | ESD rating ≥±6 kV HBM, MSL Level-3, and –40°C to +85°C operation - suitable for uncontrolled environmental deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adaptive equalizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS30BA101 | Serializer companion chip - not an equalizer; provides programmable launch amplitude but lacks adaptive CTLE. | Used on transmitter side only; requires DS30EA101 on receiver side for full cable extender functionality. | Select DS30BA101 only when building bidirectional cable extender systems with DS30EA101SQX/NOPB as the receive-side equalizer. |
| MAX9278 | Fixed-gain equalizer with selectable EQ settings (not adaptive); supports up to 3.125 Gbps but requires external configuration via I²C. | Suitable for fixed-cable-length systems where manual tuning is acceptable; lacks autonomous LOS-driven output disable. | Choose MAX9278 only if system-level control and deterministic EQ profiles are preferred over DS30EA101SQX/NOPB's zero-config adaptation. |
Compared with DS30BA101 (transmitter-only) and MAX9278 (fixed-gain, I²C-configurable), DS30EA101SQX/NOPB uniquely delivers fully autonomous, no-firmware equalization with integrated LOS/EN coordination - reducing firmware overhead and improving time-to-market for plug-and-play video extension designs.

FAQ
What is the primary function of the DS30EA101SQX/NOPB in a video transmission system?
The DS30EA101SQX/NOPB functions as an adaptive cable equalizer that automatically compensates for high-frequency signal loss in copper cables. It recovers degraded serial video data (150 Mbps to 3.125 Gbps) transmitted over coaxial or differential cables - restoring eye diagrams and enabling reliable reception at the destination without manual tuning or external configuration. DS30EA101SQX/NOPB is essential in HD surveillance and broadcast systems where cable length varies and signal integrity must be preserved.
Does the DS30EA101SQX/NOPB require external configuration or firmware to operate?
No, the DS30EA101SQX/NOPB operates autonomously with no external configuration required. Its adaptive CTLE circuitry continuously adjusts equalization gain based on real-time input signal characteristics, supporting cable lengths from zero to those inducing up to ~50 dB loss at 1.5 GHz. DS30EA101SQX/NOPB does not use I²C, SPI, or GPIO-based setup - making it ideal for firmware-light or safety-critical video systems where deterministic behavior is mandatory.
Can the DS30EA101SQX/NOPB accept both coaxial and twisted-pair cable inputs?
Yes, the DS30EA101SQX/NOPB supports both 75Ω coaxial and 100Ω differential twisted-pair cables. Its input stage accepts either differential or single-ended AC-coupled signals, and TI's reference designs validate operation with RG59 coax (up to 120 m) and CAT6 UTP (up to 50 m). DS30EA101SQX/NOPB achieves this flexibility without hardware modification - only passive termination changes are needed per cable type.
What is the role of the LOS and EN pins on the DS30EA101SQX/NOPB?
The LOS (Loss of Signal) pin outputs an LVCMOS high when no valid input signal is detected; the EN (Enable) pin controls output driver activation. When tied together, they provide automatic output disable during signal loss - preventing undefined states or noise propagation downstream. DS30EA101SQX/NOPB uses an internal pulldown on EN, so outputs remain active by default unless LOS forces EN high. This behavior is confirmed in TI's SNLS404A datasheet Figure 1 and Section "LOS AND EN".
Is the DS30EA101SQX/NOPB pin-compatible with other devices in the DS30x family?
No, DS30EA101SQX/NOPB is not pin-compatible with DS30BA101 or other members of the DS30x family. DS30BA101 is a serializer with different pin functions (e.g., CLKIN, DATAIN, REFCLK), while DS30EA101SQX/NOPB is a receiver-side equalizer with dedicated IN+/IN−, OUT+/OUT−, LOS, and EN pins. Pin mapping, power requirements, and signal flow direction differ fundamentally - direct PCB substitution is not supported. DS30EA101SQX/NOPB must be used in its intended receive position within a cable extender pair.
