Product details
Overview
DS30EA101SQ/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, delivers typical power consumption of 115 mW, operates over −40°C to +85°C, and equalizes up to 50 dB cable loss at 1.5 GHz - enabling reliable signal restoration over long coaxial or differential copper cables in security camera links.
For engineers reviewing the DS30EA101SQ/NOPB datasheet, DS30EA101SQ/NOPB pinout, DS30EA101SQ/NOPB application, or DS30EA101SQ/NOPB equivalent, key selection considerations include its LVDS output compliance, automatic equalization across SD/HD video rates, single 2.5V supply operation, industrial temperature range, and WQFN-16 package thermal performance.
Technical Context
The DS30EA101SQ/NOPB implements adaptive continuous-time linear equalization (CTLE) with real-time gain adjustment to compensate for frequency-dependent attenuation in copper channels. Its input accepts either differential (100 Ω) or single-ended (75 Ω) signals via AC coupling, and it features integrated LOS detection and LVCMOS-compatible EN control for output gating.
Internally terminated 100 Ω LVDS outputs drive standard differential receivers without external termination. The device uses a fixed 2.5 V supply and achieves <0.35 UI total jitter at 3.125 Gbps over 10 m CAT6 or 100 m RG59, confirming robust signal integrity restoration in real-world cabling environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate Range | 150 Mbps to 3.125 Gbps - supports SD, HD, and 3G-SDI video timing without retiming or clock recovery circuitry |
| Cable Loss Compensation | Up to ~50 dB @ 1.5 GHz - enables extension of 75 Ω coaxial or 100 Ω twisted-pair links beyond native reach |
| Supply Voltage | 2.5 V ±5% - single-rail operation simplifies power design versus dual-supply alternatives |
| Power Consumption | 115 mW typical - low active power supports thermally constrained PCB layouts in multi-channel camera systems |
| Operating Temperature | −40°C to +85°C - qualified for outdoor surveillance enclosures and industrial video infrastructure |
| Output Interface | LVDS (100 Ω internal termination) - directly interfaces with FPGA SerDes, video decoders, and display controllers |
| Jitter Performance | ≤0.35 UI total jitter @ 3.125 Gbps - meets eye-opening requirements for 10-m CAT6 or 100-m RG59 deployments |
Pinout & Package
DS30EA101SQ/NOPB is housed in a 4 mm × 4 mm, 16-pin WQFN package (RUM0016A) with exposed thermal pad connected to VEE. The package supports JEDEC Level-3 moisture sensitivity and 260°C peak reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 7, 8, 9, 12, DAP | VEE | Negative power supply (ground); all 7 ground pins and thermal pad must be low-inductance connected to PCB ground plane |
| 2, 3 | IN+, IN− | Differential data input; accepts AC-coupled LVDS, CML, or PECL; also supports single-ended input with proper termination |
| 10, 11 | OUT−, OUT+ | LVDS differential output; internally terminated to 100 Ω; DC-coupled compatible with downstream receivers |
| 13, 16 | VCC | +2.5 V power supply; requires local 1 µF ceramic bypass per VCC pin |
| 14 | EN | LVCMOS output enable; internal pulldown ensures default-enabled operation; tied to LOS for auto-gating |
| 15 | LOS | LVCMOS loss-of-signal indicator; high = no valid input detected; used for system fault reporting or power management |
| 5, 6 | DNC | Do not connect; floating pins must remain unconnected per TI design guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive Equalization | Automatic CTLE gain adjustment across full 150 Mbps–3.125 Gbps range eliminates manual tuning for varying cable lengths and types |
| Dual Cable Support | Validated for both 75 Ω coaxial (RG59) and 100 Ω differential (CAT6) media - reduces BOM count in mixed-cabling deployments |
| Integrated LOS Detection | On-chip signal presence monitoring enables fail-safe output disable and system-level diagnostics without external comparators |
| Low-Power LVDS Output | 115 mW typical operation with rail-to-rail LVDS swing (500–900 mVP–P) meets power budgets in multi-channel DVR/NVR designs |
| Industrial Thermal Robustness | θJA = 40°C/W and −40°C to +85°C rating support convection-cooled enclosures in uncontrolled environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adaptive equalizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS30BA101SQ/NOPB | Serializer companion chip; provides programmable launch amplitude (not equalization); requires DS30EA101 for receive-side compensation | Used on transmitter side only; cannot replace DS30EA101SQ/NOPB in receiver roles | Select DS30BA101SQ/NOPB only when building full cable extender chipset with DS30EA101SQ/NOPB |
| MAX9249GTJ+T | Fixed-gain equalizer (no adaptive loop); supports up to 3.75 Gbps but lacks LOS/EN integration; requires external biasing | Targeted at automotive GMSL2 systems; lacks industrial temp rating and coax optimization of DS30EA101SQ/NOPB | Choose MAX9249GTJ+T only for GMSL2-compliant designs where protocol alignment outweighs adaptive flexibility |
Compared with DS30BA101SQ/NOPB, DS30EA101SQ/NOPB performs receive-side correction rather than transmit-side conditioning; compared with MAX9249GTJ+T, it delivers autonomous adaptation and integrated diagnostics - making it optimal for cost-sensitive, field-deployed HD video infrastructure where cable variability is unpredictable.

FAQ
What is the primary function of the DS30EA101SQ/NOPB in a video transmission system?
The DS30EA101SQ/NOPB functions as an adaptive cable equalizer that restores high-frequency signal components attenuated during transmission over coaxial or twisted-pair copper cables. It automatically adjusts gain across 150 Mbps to 3.125 Gbps to recover SD/HD video signals - enabling longer cable runs without repeaters. DS30EA101SQ/NOPB does not perform serialization/deserialization or clock recovery; it operates purely as a signal-conditioning amplifier with built-in diagnostics.
Does the DS30EA101SQ/NOPB require external configuration or programming to operate?
No, the DS30EA101SQ/NOPB operates autonomously with zero external configuration. Its adaptive equalization algorithm self-adjusts in real time based on incoming signal characteristics, eliminating the need for I²C, SPI, or register writes. Only two passive components - AC-coupling capacitors at the input - are required for basic operation. DS30EA101SQ/NOPB is designed for plug-and-play deployment in cost-sensitive video infrastructure.
Can the DS30EA101SQ/NOPB accept single-ended input signals, and how is that implemented?
Yes, the DS30EA101SQ/NOPB supports both differential and single-ended inputs. For single-ended operation, the IN+ pin receives the signal while IN− is terminated to VEE (ground) through a 50 Ω resistor, as specified in TI's application guidance. Input must be AC-coupled with a 1.0 µF capacitor. DS30EA101SQ/NOPB maintains full data-rate support (150 Mbps–3.125 Gbps) and equalization performance in either mode.
How does the LOS and EN functionality work together in the DS30EA101SQ/NOPB?
The DS30EA101SQ/NOPB integrates LOS (loss-of-signal) detection and EN (output enable) to provide automatic output muting when no valid input is present. LOS outputs high when signal is absent; tying LOS directly to EN forces the outputs (OUT+/OUT−) into high-impedance state. This prevents downstream receivers from locking to noise or invalid data. DS30EA101SQ/NOPB's internal pulldown on EN ensures outputs remain active by default if LOS is left unconnected.
What thermal management considerations apply to the DS30EA101SQ/NOPB in high-density PCB layouts?
The DS30EA101SQ/NOPB's WQFN package includes an exposed thermal pad (DAP) that must be soldered to a dedicated PCB copper pour connected to VEE (ground) for effective heat dissipation. TI specifies θJA = 40°C/W - achievable only with ≥4 thermal vias under the pad and ≥1 in² ground plane area. Without proper thermal design, junction temperature may exceed 125°C under continuous 3.125 Gbps operation. DS30EA101SQ/NOPB's 115 mW typical power draw makes thermal layout essential in multi-channel video boards.
