Product details
Overview
DS80EP100SDX/NOPB from Texas Instruments is a passive 5–12.5 Gbps differential equalizer for FR4 backplanes and twin-axial cables, featuring 100 Ω differential impedance, 7 dB maximum boost, and zero-power operation. It compensates transmission loss and reduces deterministic jitter in high-speed serial links such as PCIe Gen1/Gen2 and XAUI interconnects between line cards and switch cards.
For engineers reviewing the DS80EP100SDX/NOPB datasheet, DS80EP100SDX/NOPB pinout, DS80EP100SDX/NOPB application, or DS80EP100SDX/NOPB equivalent, this page delivers verified technical context, symmetric I/O behavior, passive equalization performance across 5–12.5 Gbps, and placement flexibility anywhere in the data path without power or ground connections.
Technical Context
The DS80EP100SDX/NOPB implements a passive bridged-T network using resistive, capacitive, and inductive elements to deliver linear, frequency-dependent attenuation and peaking. Its response is protocol-agnostic-effective with 8b/10b, scrambled, bi-level (CML/LV-PECL/LVDS), and multi-level signaling.
It operates bidirectionally with identical compensation regardless of signal direction due to fully symmetric I/O structure. The device requires no DC bias, exhibits 100 Ω differential input/output impedance, and maintains guaranteed performance from −40°C to +85°C ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bit Rate Range | 5 to 12.5 Gbps - supports full-speed operation across PCIe Gen1 (2.5 GT/s), Gen2 (5 GT/s), and XAUI (3.125 Gbps per lane) with margin. |
| Differential Impedance | 100 Ω - matches standard differential PCB trace and cable impedance, enabling seamless integration without termination redesign. |
| Equalization Boost | Up to 7 dB at 6.25 GHz - restores high-frequency signal integrity degraded by FR4 loss or cable attenuation. |
| Residual DJ | ≤0.15 UIp-p at 5–12.5 Gbps - quantifiably reduces deterministic jitter induced by interconnect dispersion. |
| Power Requirement | No power or ground required - eliminates supply routing, decoupling, and associated noise coupling in dense high-speed layouts. |
| Signal Compatibility | CML, LV-PECL, LVDS - interoperable with major high-speed physical layer standards without level-shifting circuitry. |
Pinout & Package
DS80EP100SDX/NOPB uses a 2.2 mm × 2.5 mm, 6-pin WSON package (NGF0006A) with exposed thermal pad (DAP) left unconnected. Pins 2 and 5 are NC; DAP must remain floating per TI layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IOA+ | Differential Input/Output | High-speed balanced terminal; forms 100 Ω differential pair with IOA−; bidirectional signal path. |
| IOA− | Differential Input/Output | Complementary terminal to IOA+; enables differential signaling with common-mode rejection and EMI resilience. |
| IOB+ | Differential Input/Output | Second independent differential port; symmetric to IOA+, allowing flexible placement on either side of interconnect. |
| IOB− | Differential Input/Output | Complementary terminal to IOB+; completes second 100 Ω differential path for full-duplex or half-duplex use. |
| Pins 2, 5 & DAP | No Connect | Must remain unconnected - landing pads isolated from all planes to prevent parasitic coupling or thermal stress. |
Key Features
| Feature | Design Value |
|---|---|
| Passive Equalization | Zero-power operation eliminates supply noise, simplifies layout, and removes risk of power-rail instability affecting signal integrity. |
| Symmetric Bidirectional I/O | Identical equalization performance whether placed on transmitter or receiver side - enables single BOM item for Tx/Rx paths. |
| Protocol-Agnostic Compensation | Validated with PRBS-7 patterns across 5–12.5 Gbps; works with scrambled, 8b/10b, and multi-level encoding without reconfiguration. |
| FR4 & Cable Reach Extension | Extends usable length of 6-mil FR4 microstrip up to 30 inches at 5 Gbps and 14 inches at 12.5 Gbps while maintaining eye height >0.4 V. |
| Small Footprint Integration | 2.2 mm × 2.5 mm WSON package allows placement directly adjacent to connectors or ASICs without routing detours. |
Applications
| PCIe Backplane Interconnect | XAUI Switch Fabric |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive equalizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS80EV100SD/NOPB | Same 6-pin WSON package but rated for 10–14 Gbps; higher-frequency peaking profile optimized for 100GbE CAUI. | Targeted at 100G Ethernet and higher-speed optical interfaces; not validated below 10 Gbps. | Select DS80EV100SD/NOPB only when operating ≥10 Gbps and requiring extended high-frequency boost beyond DS80EP100SDX/NOPB's 6.25 GHz peak. |
| MAX3801ETM+ | Active equalizer requiring ±3.3 V supplies; provides programmable gain and adaptive control; 100 Ω differential I/O. | Used where dynamic channel adaptation or variable loss compensation is needed; adds power, layout, and control complexity. | Choose MAX3801ETM+ only if real-time adjustment or wider loss variation (>15 dB) must be handled; DS80EP100SDX/NOPB suffices for static, known-loss channels. |
Compared with DS80EV100SD/NOPB, DS80EP100SDX/NOPB offers broader low-to-mid-bandwidth coverage (5–12.5 Gbps) and simpler integration; versus MAX3801ETM+, it eliminates supply dependencies and control overhead while delivering deterministic jitter reduction in fixed-loss environments.

FAQ
Does DS80EP100SDX/NOPB require any power supply or biasing?
No, DS80EP100SDX/NOPB is a fully passive device requiring no power or ground connections. It operates solely through its internal resistive-capacitive-inductive network, eliminating supply noise, decoupling capacitors, and layout constraints associated with powered equalizers. This makes DS80EP100SDX/NOPB ideal for space-constrained and ultra-low-noise applications where even minor supply ripple could degrade signal integrity.
Can DS80EP100SDX/NOPB be used bidirectionally in the same data path?
Yes, DS80EP100SDX/NOPB features symmetric I/O structures that provide identical equalization performance regardless of signal direction. Whether placed between a line card transmitter and switch card receiver-or vice versa-the DS80EP100SDX/NOPB delivers consistent 7 dB boost and deterministic jitter reduction. This symmetry enables single-part deployment in full-duplex systems like XAUI or PCIe root complex-to-endpoint links.
What is the maximum supported trace length for DS80EP100SDX/NOPB at 10 Gbps?
At 10 Gbps, DS80EP100SDX/NOPB extends usable FR4 microstrip length to 30 inches while maintaining >0.4 V eye height and ≤0.20 UIp-p residual deterministic jitter. This performance is validated using 6-mil traces on standard FR4 material. For longer runs or higher loss media (e.g., 26AWG twin-ax), DS80EP100SDX/NOPB supports up to 5 meters at 10 Gbps with measurable eye recovery, as confirmed in TI's Figure 32 eye diagrams.
Is DS80EP100SDX/NOPB compatible with LVDS signaling?
Yes, DS80EP100SDX/NOPB is explicitly specified to equalize LVDS, CML, and LV-PECL signals. Its 100 Ω differential impedance and linear passive response ensure compatibility with LVDS voltage swings (typically 350 mV p-p) and common-mode ranges (1.2 V nominal). No level-shifting or AC-coupling adjustments are needed-DS80EP100SDX/NOPB integrates directly into LVDS-based backplane or cable interconnects.
What package type and footprint does DS80EP100SDX/NOPB use?
DS80EP100SDX/NOPB uses a 2.2 mm × 2.5 mm, 6-pin WSON package (TI package code NGF0006A) with an exposed thermal pad (DAP) that must remain unconnected. Pins 2 and 5 are NC. The compact footprint enables placement directly at connector interfaces or near ASIC I/O banks, minimizing stub length and preserving signal integrity. Full mechanical drawings are available in TI's NGF0006A datasheet.
