Product details
Overview
DS15EA101SQE/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 LOS detection and output enable, and operates from a single 3.3 V supply with 210 mW typical power at 1.5 Gbps - deployed in security camera video extension over CAT5e/6/7 or coaxial cables.
For engineers reviewing the DS15EA101SQE/NOPB datasheet, DS15EA101SQE/NOPB pinout, DS15EA101SQE/NOPB application, or DS15EA101SQE/NOPB equivalent, key selection criteria include adaptive equalization range (0–35 dB), differential input/output compatibility (CML/LVPECL/LVDS), 4×4 mm WQFN-16 thermal performance, and industrial −40°C to +85°C operation for embedded video transport systems.
Technical Context
The DS15EA101SQE/NOPB implements a continuous-time linear equalizer (CTLE) with adaptive loop control via CAP+/CAP− pins, automatically adjusting gain and frequency response to compensate for cable attenuation up to 35 dB at 750 MHz. Its architecture accepts both single-ended and differential inputs and drives 50 Ω differential CML outputs without external termination.
It integrates a loss-of-signal (LOS) detector that asserts high when input amplitude falls below threshold, and an EN pin that synchronously disables outputs - enabling power-aware receiver-side blanking in SerDes link training. Jitter performance is characterized at BER-12, with residual jitter ≤0.25 UI across multiple cable types and data rates.
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 over copper. |
| Equalization Boost | Up to 35 dB at 750 MHz - recovers signals degraded by long CAT5e (100 m), CAT7 (75 m), or Belden 9914 (200 m) cables. |
| Input Interface | Single-ended or differential AC-coupled - enables interoperability with LVDS, CML, and LVPECL SerDes sources without level-shifting. |
| Output Drive | 50 Ω differential CML - directly interfaces to standard high-speed receivers (e.g., DS15BA101, FPGA transceivers) without external termination. |
| Power Consumption | 77 mA typical at 3.3 V (210 mW) - scales inversely with cable loss, reducing current as equalization demand increases. |
| Operating Temperature | −40°C to +85°C - qualified for outdoor security cameras, industrial displays, and remote LED panels. |
| Jitter Performance | ≤0.25 UI total residual jitter @ BER-12 - ensures reliable clock/data recovery in multi-drop video distribution systems. |
Pinout & Package
DS15EA101SQE/NOPB uses a 4×4 mm, 16-pin WQFN package (RGH0016A) with exposed thermal pad for enhanced thermal dissipation. The package is RoHS-compliant, moisture-sensitive Level-3, and rated for reflow at 260°C peak.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,4,7,8,9,12) | Ground reference | Six dedicated ground pins minimize noise coupling and support stable high-frequency equalization loop operation. |
| IN+, IN− (Pins 2,3) | Differential input | Accepts AC-coupled LVDS/CML/LVPECL signals; common-mode voltage 1.9 V enables compatibility with 3.3 V SerDes outputs. |
| CAP+, CAP− (Pins 5,6) | Adaptive loop filter | Connects external 1.0 µF capacitor pair to set equalizer bandwidth and convergence behavior per cable type. |
| OUT+, OUT− (Pins 11,10) | Differential output | 50 Ω CML outputs drive 100 Ω differential lines directly; no external termination required. |
| VCC (Pins 13,16) | Supply rail | Dual 3.3 V supply pins reduce IR drop and improve PSRR for low-jitter signal regeneration. |
| EN (Pin 14) | Output enable | Active-low control synchronizes output disable with LOS assertion to suppress spurious transitions during link idle. |
| LOS (Pin 15) | Loss-of-signal indicator | Open-drain output asserts high when input amplitude drops below detection threshold - used for link health monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive equalization | Automatically adjusts gain and pole/zero placement across 150 Mbps–1.5 Gbps to match real-time cable loss - eliminates manual tuning for varying cable lengths. |
| Multi-cable support | Validated on 100 Ω twisted-pair (CAT5e/6/7), 100 Ω twinax, and 50 Ω coaxial (Belden 9914) - enables single design reuse across surveillance, broadcast, and industrial display interconnects. |
| Integrated LOS + EN logic | LOS and EN pins can be tied together to blank outputs during signal loss - prevents false triggering in downstream receivers and reduces system-level EMI. |
| Low-power CML output stage | 50 Ω differential outputs consume only 210 mW at 1.5 Gbps - enables dense channel count in multi-camera DVR/NVR boards without thermal throttling. |
| Industrial temperature grade | Specified from −40°C to +85°C - supports deployment in uncontrolled environments such as traffic intersections, factory floors, and outdoor kiosks. |

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 chip with programmable output amplitude; not an equalizer - requires DS15EA101 for receive-side compensation. | Used on transmitter side only; cannot replace DS15EA101SQE/NOPB in receiver position. | Select DS15BA101 only when building full cable extender chipset; not a functional substitute. |
| LMH0384 | Fixed-gain equalizer (no adaptive loop); supports up to 2.97 Gbps but lacks LOS/EN integration and operates from 2.5 V. | Targeted at SMPTE 292/344 broadcast video; less flexible for mixed-cable industrial use cases. | Choose LMH0384 only if fixed 2.5 V supply and non-adaptive equalization suffice - no automatic cable-length adaptation. |
Compared with DS15BA101 (transmitter-only) and LMH0384 (fixed-gain, 2.5 V), DS15EA101SQE/NOPB uniquely combines adaptive CTLE, integrated LOS/EN logic, 3.3 V operation, and multi-cable qualification - making it the sole option for self-calibrating, low-power, industrial-grade receiver-side equalization in 150 Mbps–1.5 Gbps links.

FAQ
What is the primary function of the DS15EA101SQE/NOPB in a video transmission system?
The DS15EA101SQE/NOPB functions as an adaptive cable equalizer that restores high-frequency content lost due to attenuation in copper cables. It dynamically compensates for signal degradation across 150 Mbps–1.5 Gbps data streams, enabling reliable HD-SDI and digital video transport over CAT5e/6/7 and coaxial cables up to 200 m. Its role is critical in maintaining signal integrity at the receiver end of SerDes-based links.
Does the DS15EA101SQE/NOPB require external components for basic operation?
Yes - the DS15EA101SQE/NOPB requires two 1.0 µF capacitors between CAP+ and CAP− pins to configure its adaptive equalization loop. Input and output paths must also be AC-coupled with 1.0 µF series capacitors. No external termination resistors are needed, as the 50 Ω differential outputs are internally matched.
Can the DS15EA101SQE/NOPB interface directly with LVDS receivers?
Yes - the DS15EA101SQE/NOPB's 50 Ω CML outputs can DC-couple to standard LVDS receivers with high-impedance inputs and compatible common-mode voltage range (typically 1.0–1.4 V). TI provides reference schematics showing direct connection to LVDS inputs, though receiver datasheet validation is recommended per application.
How does the LOS output of the DS15EA101SQE/NOPB behave under signal loss conditions?
The LOS pin of the DS15EA101SQE/NOPB is an open-drain output that pulls high (≥2.6 V) when valid input signal amplitude falls below detection threshold, and pulls low (≤0.4 V) when signal is present. When tied to the EN pin, it automatically disables outputs during loss-of-signal events - preventing false data capture and reducing downstream EMI.
Is the DS15EA101SQE/NOPB pin-compatible with other devices in the DS15x family?
No - the DS15EA101SQE/NOPB has a unique pinout optimized for adaptive equalization, including dedicated CAP+ and CAP− terminals. It is not pin-compatible with DS15BA101 (serializer) or DS15EA010 (older generation), which differ in pin assignment, functionality, and loop filter requirements.
