Product details
Overview
DS15EA101SQ/NOPB from Texas Instruments is an adaptive cable equalizer IC designed for high-speed serial data recovery over lossy copper media. It supports 150 Mbps to 1.5+ Gbps data rates, delivers up to 35 dB boost at 750 MHz, features integrated LOS detection and output enable, and operates from a single 3.3 V supply in security camera video links.
For engineers reviewing the DS15EA101SQ/NOPB datasheet, DS15EA101SQ/NOPB pinout, DS15EA101SQ/NOPB application, or DS15EA101SQ/NOPB equivalent, key selection criteria include differential cable loss compensation capability, residual jitter performance at 1.5 Gbps, CML/LVDS output compatibility, and WQFN-16 thermal management under industrial temperature conditions.
Technical Context
The DS15EA101SQ/NOPB implements adaptive continuous-time linear equalization (CTLE) with automatic loop filter tuning via CAP+/CAP− pins, enabling real-time compensation of frequency-dependent attenuation across coaxial (50 Ω), twin-ax, and twisted-pair (100 Ω) cables. Its architecture accepts AC-coupled single-ended or differential inputs and generates internally terminated 50 Ω CML outputs.
Operation requires no external configuration: equalization gain adjusts dynamically based on input signal integrity, while LOS detection asserts low when input amplitude falls below threshold. The device maintains ≤0.25 UI total residual jitter at 1.5 Gbps over 50 m CAT5e and 200 m Belden 9914 coaxial cable per TI SNLS235H.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate Range | 150 Mbps to 1.5+ Gbps - supports legacy SD/HD video and modern HD-SDI/12G-SDI transport without retiming. |
| Equalization Boost | Up to 35 dB at 750 MHz - recovers signals degraded by ≥35 dB cable loss, enabling 100+ m CAT5e or 200 m coaxial runs. |
| Output Type | 50 Ω differential CML - directly interfaces with LVDS, LVPECL, and CML receivers without external termination. |
| Power Consumption | 210 mW typical at 1.5 Gbps - enables multi-channel deployment in thermally constrained enclosures. |
| Operating Temp | −40°C to +85°C - qualified for outdoor security cameras, remote displays, and industrial video infrastructure. |
| Supply Voltage | 3.3 V ±5% - compatible with standard industrial power rails and avoids level-shifting complexity. |
| Residual Jitter | ≤0.25 UI at 1.5 Gbps - ensures BER <10⁻¹² in noise-sensitive video transmission systems. |
Pinout & Package
DS15EA101SQ/NOPB uses a 4 mm × 4 mm WQFN-16 package (RGH0016A) with exposed thermal pad for enhanced heat dissipation. Pin 1 index is marked by a corner chamfer; the exposed pad must be soldered to PCB ground for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,4,7,8,9,12) | Ground reference | Six dedicated ground pins minimize ground bounce and ensure stable common-mode rejection across full bandwidth. |
| IN+, IN− (Pins 2,3) | Differential input | AC-coupled inputs accept 800 mVP-P differential or 800 mV single-ended signals; transformer coupling not supported. |
| CAP+, CAP− (Pins 5,6) | Loop filter interface | Connects to external 1.0 µF capacitor pair to set adaptive equalization time constant and stability margin. |
| OUT+, OUT− (Pins 11,10) | Differential CML output | 50 Ω internally terminated current-mode outputs drive 100 Ω differential lines or 50 Ω coaxial cables directly. |
| VCC (Pins 13,16) | Power supply | Dual 3.3 V supply pins reduce IR drop and improve PSRR at high frequencies. |
| EN (Pin 14) | Output enable | Active-high control disables outputs when tied to LOS for automatic power-down during signal loss. |
| LOS (Pin 15) | Loss-of-signal indicator | Open-drain output asserts low when input amplitude drops below detection threshold; used for system fault reporting. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive equalization | Automatic CTLE gain adjustment compensates variable cable lengths (0–200 m) without manual tuning or firmware. |
| Multi-cable support | Validated for 50 Ω coaxial (Belden 9914), 100 Ω twisted pair (CAT5e/6/7), and twin-axial cables per TI test data. |
| Integrated LOS + EN logic | Hardware-level signal monitoring and output gating eliminate need for external microcontroller supervision. |
| Low-power CML outputs | 210 mW operation at 1.5 Gbps enables dense channel count in space-constrained video distribution hubs. |
| Industrial temperature range | −40°C to +85°C operation supports deployment in uncontrolled environments like traffic intersections or factory floors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adaptive equalizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS15BA101 | Serializer companion with programmable output swing; lacks LOS detection and adaptive equalization. | Used on transmitter side only; requires DS15EA101 for full cable extension functionality. | Select DS15BA101 only when building complete TI chipset solution; not standalone replacement. |
| MAX3801 | Fixed-gain 3.2 Gbps equalizer with 20 dB max boost; no adaptive loop or LOS output. | Requires external gain setting and signal monitoring circuitry; limited to shorter cable runs (<15 dB loss). | Choose MAX3801 only for fixed-length coaxial links where adaptive control adds unnecessary complexity. |
Compared with DS15BA101 and MAX3801, the DS15EA101SQ/NOPB uniquely combines adaptive gain, integrated LOS, and industrial temperature operation in a single 4×4 mm WQFN package-enabling robust, maintenance-free video extension without external supervision or calibration.

FAQ
What is the maximum cable loss that DS15EA101SQ/NOPB can compensate?
The DS15EA101SQ/NOPB provides up to 35 dB of adaptive boost at 750 MHz, validated to recover signals attenuated by 35 dB at that frequency. This enables reliable operation over 100 m CAT5e or 200 m Belden 9914 coaxial cable per TI SNLS235H characterization data. Performance scales with data rate: at 1.5 Gbps, it sustains ≤0.25 UI residual jitter even after 200 m coaxial transmission.
Does DS15EA101SQ/NOPB require external configuration or programming?
No, DS15EA101SQ/NOPB operates autonomously with no external configuration required. Its adaptive equalization engine self-adjusts gain and frequency response based on input signal integrity. Only two passive components-a 1.0 µF capacitor pair between CAP+ and CAP−-are needed to set loop dynamics. No I²C, SPI, or firmware interface exists on the DS15EA101SQ/NOPB.
Can DS15EA101SQ/NOPB interface directly with LVDS receivers?
Yes, DS15EA101SQ/NOPB's 50 Ω differential CML outputs are compatible with LVDS receivers when DC-coupled, as confirmed in TI's Figure 1 application schematic. The output common-mode voltage (VOS) is VCC/2 = 1.65 V, falling within typical LVDS receiver input common-mode range (0.2 V to 2.3 V). No level-shifting circuitry is needed for direct connection.
What is the role of the EN and LOS pins on DS15EA101SQ/NOPB?
The LOS pin is an open-drain output asserting low when input signal amplitude drops below detection threshold; EN is an active-high enable controlling output driver state. When tied together, they form hardware-level automatic power-down: outputs disable during signal loss, reducing system power by ~210 mW. This behavior is intrinsic to DS15EA101SQ/NOPB and requires no external logic.
Is DS15EA101SQ/NOPB RoHS compliant and lead-free?
Yes, DS15EA101SQ/NOPB is RoHS compliant and lead-free. Per TI's packaging addendum, it carries "Green (RoHS & no Sb/Br)" eco plan designation, with Sn (tin) lead finish and MSL Level-3 rating (260°C peak reflow, 168-hour floor life). The "NOPB" suffix explicitly confirms lead-free compliance per JEDEC J-STD-609.
