Product details
Overview
DS32EV100SD/NOPB from Texas Instruments is a programmable single-channel CML equalizer optimized for high-speed serial links up to 3.2 Gbps, compensating up to 14 dB loss on 40-inch FR4 traces while delivering 0.12 UI residual deterministic jitter at 3.2 Gbps; it serves as a front-end signal conditioner in backplane and cable interconnects between ASIC/FPGA and switch fabric or line cards.
For engineers reviewing the DS32EV100SD/NOPB datasheet, DS32EV100SD/NOPB pinout, DS32EV100SD/NOPB application, or DS32EV100SD/NOPB equivalent, this page delivers verified electrical parameters, WSON-14 package layout, eight-level programmable boost control, AC/DC coupling support, and real-world jitter performance metrics for NRZ data channels.
Technical Context
The DS32EV100SD/NOPB implements a fixed-gain limiting amplifier with integrated DC offset correction and an adjustable equalization stage controlled by three LVCMOS BST pins (BST_0–BST_2), enabling eight discrete boost levels per Table 1. Its CML I/O architecture supports differential 100 Ω input termination and 50 Ω output terminations to VDD.
It operates across −40°C to +85°C with dual-supply compatibility (2.5 V ±5% or 3.3 V ±10%), achieves <100 mW typical power consumption at 2.5 V, and maintains >8 kV HBM ESD rating - all within a 3 mm × 4 mm WSON package with exposed thermal pad tied to GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 3.2 Gbps - supports XAUI, SATA, and 10G-KR-compatible NRZ channels without retiming. |
| Equalization Range | Up to 14 dB at 3.2 Gbps - restores signal integrity degraded by FR4 trace or twin-axial cable loss. |
| Residual DJ @ 3.2 Gbps | 0.12 UI peak-to-peak - measured on 40" FR4 microstrip with PRBS-7 pattern, enabling clean eye opening. |
| Supply Voltage | 2.5 V ±5% or 3.3 V ±10% - allows flexible integration into 2.5 V or 3.3 V system rails. |
| Power Consumption | 100 mW typ at 2.5 V - enables low-power hot-swappable line card designs with minimal thermal impact. |
| Input Termination | On-chip 100 Ω differential - eliminates external termination resistors and simplifies PCB layout. |
| Output Termination | On-chip 50 Ω to VDD - supports direct connection to downstream CML receivers without external biasing. |
| ESD Rating | >8 kV HBM - meets industrial-grade robustness requirements for field-deployable telecom hardware. |
Pinout & Package
DS32EV100SD/NOPB uses a 3 mm × 4 mm, 14-pin WSON package (TI package code NHK0014A) with exposed thermal pad (DAP) connected to GND. The package is RoHS-compliant, moisture-sensitivity level 1, and rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+, IN− | CML differential input | Accepts AC- or DC-coupled NRZ signals; internally terminated with 100 Ω differential resistor. |
| OUT+, OUT− | CML differential output | Drives downstream receiver with 50 Ω on-chip termination to VDD; 550–725 mVP-P swing. |
| BST_0, BST_1, BST_2 | LVCMOS equalizer control | Select one of eight boost levels; BST_2 internally pulled high, BST_0/BST_1 internally pulled low. |
| VDD | Power supply | Single rail: 2.5 V ±5% or 3.3 V ±10%; requires local 0.01 µF bypass capacitor per pin. |
| GND (Pins 2,6,9,10,13 + DAP) | Ground reference | Five dedicated GND pins plus exposed pad ensure low-inductance return path for high-frequency currents. |
| NC (Pin 1) | No-connect | Reserved pin; must remain unconnected per TI specification. |
Key Features
| Feature | Design Value |
|---|---|
| Eight-level programmable equalization | Enables precise compensation tuning across varying channel losses (e.g., 0–40" FR4 or 0–10 m twin-ax) via simple 3-pin binary control. |
| Integrated 100 Ω differential input termination | Eliminates need for external termination resistors, reducing BOM count and improving impedance matching consistency. |
| On-chip 50 Ω output termination to VDD | Permits direct interface to CML receivers without external pull-up resistors or level-shifting circuitry. |
| AC/DC coupling support | Accepts both coupling types: AC-coupled with external capacitors or DC-coupled with VICMDC common-mode compliance (VDDTX − 0.8 V to VDDTX − 0.2 V). |
| Low-power CML architecture | Consumes only 100 mW typical at 2.5 V, enabling dense deployment in power-constrained switch fabric cards. |
| High ESD robustness | >8 kV HBM rating ensures reliability during board handling, insertion, and field maintenance in telecom infrastructure. |
Applications
| Switch Fabric Card | Line Card |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed equalizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS100BR111SQ/NOPB | Retimer with integrated CDR; higher power (220 mW), supports up to 10.3125 Gbps; no programmable EQ levels. | Used where clock recovery is required; not suitable for pure EQ-only use cases due to added latency and complexity. | Choose DS100BR111SQ/NOPB only if CDR functionality is needed; DS32EV100SD/NOPB remains optimal for low-latency, low-power EQ-only roles. |
| MAX3801ETJ+ | Fixed-gain equalizer (no programmability); 3.2 Gbps max; 100 Ω input, 50 Ω output; 2.5 V only; 16-TQFN package. | Limited to fixed-loss environments; lacks BST control flexibility for dynamic channel adaptation. | Choose MAX3801ETJ+ only for cost-sensitive, static-layout applications where loss profile is invariant; DS32EV100SD/NOPB preferred for field-upgradable systems. |
Compared with DS100BR111SQ/NOPB and MAX3801ETJ+, DS32EV100SD/NOPB uniquely balances programmable equalization, ultra-low latency, sub-100 mW power, and WSON space efficiency - making it the optimal choice for FPGA/ASIC-facing EQ-only functions in compact line cards and switch fabrics.

FAQ
What is the maximum supported data rate for DS32EV100SD/NOPB?
The DS32EV100SD/NOPB is characterized and specified to operate reliably up to 3.2 Gbps with PRBS-7 patterns on 40-inch FR4 traces. It maintains 0.12 UI residual deterministic jitter at this rate and supports lower rates including 1 Gbps and 2.5 Gbps with correspondingly reduced DJ (0.05 UI and 0.10 UI respectively). Operation beyond 3.2 Gbps is not guaranteed or tested.
Does DS32EV100SD/NOPB require external termination resistors?
No. DS32EV100SD/NOPB integrates a 100 Ω differential termination between IN+ and IN−, and 50 Ω single-ended terminations from OUT+ and OUT− to VDD. These on-chip terminations eliminate the need for external resistors, simplifying layout and improving impedance consistency across production units.
Can DS32EV100SD/NOPB be used with DC-coupled inputs?
Yes. DS32EV100SD/NOPB supports both AC- and DC-coupled inputs. For DC coupling, the input common-mode voltage must fall within VICMDC = VDDTX − 0.8 V to VDDTX − 0.2 V, and the downstream receiver must be powered synchronously to avoid ESD structure activation during power sequencing.
How is equalization strength selected on DS32EV100SD/NOPB?
Equalization strength is set using three LVCMOS control pins: BST_0, BST_1, and BST_2. These pins configure one of eight boost levels per TI's EQ Boost Control Table. BST_2 is internally pulled high; BST_0 and BST_1 are internally pulled low, allowing simple strapping without external biasing for default level 0x04 (10" FR4).
What package type and thermal considerations apply to DS32EV100SD/NOPB?
DS32EV100SD/NOPB uses a 3 mm × 4 mm, 14-pin WSON package (NHK0014A) with an exposed thermal pad (DAP) that must be soldered to a solid GND plane. Thermal resistance θJA is 40 °C/W with no airflow; proper PCB layout - including multiple GND vias under the DAP and localized 0.01 µF bypass capacitors on each VDD pin - is essential for thermal stability and signal integrity.
