Product details
Overview
DS32EV100SDX/NOPB from Texas Instruments is a programmable single-channel CML equalizer IC designed for high-speed serial links in backplane and cable interconnects. It delivers up to 14 dB equalization at 3.2 Gbps, achieves 0.12 UI residual deterministic jitter on 40" FR4 traces, operates from a single 2.5V or 3.3V supply, and is housed in a 3 mm × 4 mm 14-pin WSON package - enabling signal integrity restoration in switch fabric cards and line cards.
For engineers reviewing the DS32EV100SDX/NOPB datasheet, DS32EV100SDX/NOPB pinout, DS32EV100SDX/NOPB application, or DS32EV100SDX/NOPB equivalent, this page provides verified electrical specifications, validated pin functions, confirmed operating conditions (−40°C to +85°C), real-world jitter performance data, and direct alternative options for high-speed NRZ channel equalization.
Technical Context
The DS32EV100SDX/NOPB implements a fully integrated CML-based equalization channel with DC offset correction, limiting amplifier, and output driver. Its eight-level programmable boost control (via BST_0–BST_2) enables precise compensation across loss profiles from 5" to 40" FR4 or up to 10 m of 24 AWG Twin-AX cable.
It supports both AC- and DC-coupled inputs with wide common-mode range (VICMDC = VDDTX − 0.8 V to VDDTX − 0.2 V), features on-chip 100 Ω differential input termination and 50 Ω output terminations to VDD, and maintains < 0.2 UI deterministic jitter at 3.2 Gbps under worst-case channel loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Equalization Range | Up to 14 dB at 3.2 Gbps - compensates severe frequency-dependent loss in long FR4 traces or passive cables. |
| Data Rate Support | DC to 3.2 Gbps NRZ - validated for XAUI (3.125 Gbps), 10GBASE-KR, and custom high-speed serial protocols. |
| Residual DJ @ 3.2 Gbps | 0.12 UI (typ) on 40" FR4 - directly reduces eye closure caused by intersymbol interference in backplane channels. |
| Supply Voltage | 2.5 V ±5% or 3.3 V ±10% - dual-voltage compatibility simplifies integration into mixed-supply FPGA/ASIC I/O subsystems. |
| Power Consumption | 100 mW (typ) at 2.5 V - enables dense placement in power-constrained line cards without thermal derating. |
| ESD Rating | > 8 kV HBM - robust enough for handling during board assembly and field-replaceable module insertion. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and telecom infrastructure environments including central office and base station equipment. |
Pinout & Package
DS32EV100SDX/NOPB uses a 3 mm × 4 mm, 0.5 mm pitch, 14-pin WSON package (TI package code NHK0014A) with exposed thermal pad (DAP) tied to ground. The package supports reflow per JEDEC Level-1-260°C and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+, IN− | CML differential input | Accepts AC/DC-coupled NRZ signals; includes internal 100 Ω differential termination - eliminates external resistors. |
| OUT+, OUT− | CML differential output | Drives downstream ASIC/FPGA with 550–725 mVP-P swing; internally terminated to VDD via 50 Ω - no external biasing required. |
| BST_0, BST_1, BST_2 | Equalization strength control | LVCMOS inputs selecting one of eight boost levels (0x00–0x07); BST_2 pulled high internally, BST_0/BST_1 pulled low. |
| VDD | Power supply | Single rail supporting 2.5 V or 3.3 V; requires local 0.01 μF bypass capacitor per pin for high-frequency noise suppression. |
| GND (Pins 2,6,9,10,13 + DAP) | Ground reference | Five dedicated GND pins plus exposed pad ensure low-inductance return path - critical for CML signal integrity at 3.2 Gbps. |
| NC (Pin 1) | No-connect | Reserved pin; must remain unconnected - no internal circuitry or test function attached. |
Key Features
| Feature | Design Value |
|---|---|
| Eight-level programmable equalization | Enables precise tuning to match actual channel loss profile - avoids over-equalization-induced noise peaking. |
| Integrated 100 Ω input / 50 Ω output termination | Eliminates need for external termination resistors - saves PCB area and reduces parasitic effects in high-speed routing. |
| DC and AC coupling support | Allows interoperability with both legacy LVDS/PECL drivers and modern CML transceivers without level-shifting circuitry. |
| Low residual deterministic jitter (0.12 UI) | Preserves timing margin in multi-gigabit systems - directly extends usable trace length without retiming. |
| Small 3 mm × 4 mm WSON footprint | Enables placement adjacent to FPGA/ASIC BGA packages - minimizes interconnect length and insertion loss. |
Applications
| Switch Fabric Card | Line Card |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed serial equalizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3801ETJ+ | Fixed 12 dB equalization; no programmability; operates up to 2.5 Gbps only. | Suitable for cost-sensitive, lower-data-rate backplanes where channel loss is stable and known. | Select when fixed gain suffices and 3.2 Gbps support is unnecessary - avoids control pin routing overhead. |
| DS100BR111SQ/NOPB | Redriver (not equalizer); regenerates signal with decision feedback; supports up to 10.3125 Gbps. | Used where full retiming is needed - e.g., longer channels or multi-lane systems requiring lane deskew. | Choose when deterministic jitter exceeds 0.3 UI or when clock recovery is required - DS32EV100SDX/NOPB does not recover clock. |
Compared with MAX3801ETJ+ and DS100BR111SQ/NOPB, DS32EV100SDX/NOPB uniquely balances programmable equalization, low power (100 mW), and compact WSON packaging for mid-speed (≤3.2 Gbps) FR4/cable channels - making it optimal for space-constrained, thermally sensitive switch fabric and line card designs where retiming adds unnecessary latency and complexity.

FAQ
What is the maximum supported data rate for DS32EV100SDX/NOPB?
The DS32EV100SDX/NOPB is characterized and specified to operate reliably up to 3.2 Gbps with NRZ signaling. Performance validation includes eye diagrams and jitter measurements at 1 Gbps, 2.5 Gbps, and 3.2 Gbps on 40" FR4 and 10 m Twin-AX cable - confirming full functionality across this range. Operation beyond 3.2 Gbps is not guaranteed and falls outside the device's qualified specification.
Does DS32EV100SDX/NOPB require external termination resistors?
No, DS32EV100SDX/NOPB integrates all necessary termination: a 100 Ω differential resistor between IN+ and IN−, and 50 Ω single-ended resistors from OUT+ and OUT− to VDD. This eliminates external termination components, reduces PCB layout complexity, and minimizes parasitic effects that degrade high-speed signal integrity at 3.2 Gbps.
Can DS32EV100SDX/NOPB be used with DC-coupled inputs?
Yes, DS32EV100SDX/NOPB supports DC coupling. For DC-coupled operation, the input common-mode voltage must be within VICMDC = VDDTX − 0.8 V to VDDTX − 0.2 V, and the output must be terminated to VDD (not ground). Power-up/power-down sequencing with the downstream receiver is required to prevent ESD structure activation during transition states.
How many equalization levels does DS32EV100SDX/NOPB provide, and how are they selected?
DS32EV100SDX/NOPB provides eight discrete equalization levels (0x00 through 0x07), controlled by the BST_0, BST_1, and BST_2 pins. BST_2 is internally pulled high; BST_0 and BST_1 are internally pulled low. These three LVCMOS inputs allow direct hardware configuration without I²C or SPI - enabling fast, deterministic setup in FPGA-adjacent placements.
What package type and thermal characteristics apply to DS32EV100SDX/NOPB?
DS32EV100SDX/NOPB uses a 3 mm × 4 mm, 14-pin WSON package (TI package code NHK0014A) with exposed thermal pad (DAP) connected to ground. Its thermal resistance θJA is 40 °C/W with no airflow, and it is rated for JEDEC Level-1 moisture sensitivity with peak reflow at 260°C - ensuring compatibility with standard SMT assembly processes.
