Product details
Overview
DS25CP102QSQ/NOPB from Texas Instruments is an AEC-Q100 Grade 3 automotive-qualified 2×2 LVDS crosspoint switch supporting DC–3.125 Gbps data rates, featuring pin-selectable transmit pre-emphasis and receive equalization, on-chip 100 Ω differential termination, and low jitter (≤0.11 UIP-P at 3.125 Gbps) for high-integrity signal routing in display backplanes and SDI routers.
For engineers reviewing the DS25CP102QSQ/NOPB datasheet, DS25CP102QSQ/NOPB pinout, DS25CP102QSQ/NOPB application, or DS25CP102QSQ/NOPB equivalent, key selection criteria include its 3.125 Gbps bandwidth with EQ/PE configurability, flow-through WQFN-16 pinout for FR-4 loss compensation, automotive temperature range (−40°C to +85°C), and LVDS/CML/LVPECL interoperability via wide common-mode input range.
Technical Context
The DS25CP102QSQ/NOPB implements a fully differential, non-blocking 2×2 crosspoint architecture with independent output enable (EN0/EN1) and configuration control (SEL0/SEL1), enabling any input-to-output mapping including broadcast (IN0→OUT0+OUT1). Its signal path avoids active gain stages, preserving signal integrity through passive switching with internal 100 Ω termination.
Transmit pre-emphasis (PE pin) and receive equalization (EQ pin) operate as binary ON/OFF controls-no programmable tap weights-each reducing deterministic jitter by up to 16 ps at 3.125 Gbps over 30-inch FR-4 striplines. Jitter performance is characterized per PRBS-23 NRZ patterns with subtraction of input stimulus jitter.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 3.125 Gbps - supports OC-48/STM-16, 3G-SDI, and automotive pixel clock distribution without retiming. |
| Differential Jitter (TJ) | 0.05–0.11 UIP-P at 3.125 Gbps - ensures >80% eye opening under worst-case EQ/PE settings for reliable sampling. |
| Propagation Skew | tSKD2 ≤ 25 ps (channel-to-channel), tSKD3 ≤ 150 ps (part-to-part) - enables synchronous multi-lane routing in display timing paths. |
| Input Common-Mode Range | 0.05 V to (VCC − 0.05 V) - allows direct DC-coupling to LVPECL (2.5 V/3.3 V), CML, and LVDS drivers without level-shifting circuitry. |
| Supply Current | 77–90 mA (active), 23–29 mA (outputs disabled) - enables low-power operation in always-on automotive infotainment domains. |
| ESD Rating | ±8 kV HBM on LVDS I/O - protects against electrostatic discharge during assembly and in-vehicle cable hot-plug events. |
| Operating Temperature | −40°C to +85°C - qualified per AEC-Q100 Grade 3 for under-dash and center-stack automotive electronics. |
Pinout & Package
DS25CP102QSQ/NOPB uses a 4 mm × 4 mm WQFN-16 package (RGH0016A) with exposed thermal pad (DAP) and flow-through pin assignment optimized for minimal trace stubs on FR-4 PCBs. The pinout supports symmetric layout routing with differential pairs aligned on opposite sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0+, IN0− / IN1+, IN1− | Differential LVDS inputs | Accept LVDS/CML/LVPECL signals; internally terminated 100 Ω; wide VCM enables DC coupling without AC caps. |
| OUT0+, OUT0− / OUT1+, OUT1− | Differential LVDS outputs | LVDS-compliant outputs (250–450 mV VOD); 100 Ω on-chip termination eliminates external resistors. |
| SEL0, SEL1 | Configuration select | Set crosspoint routing (IN0/IN1 → OUT0/OUT1); 20 kΩ pulldown ensures default state on power-up. |
| EN0, EN1 | Output enable | Independently disable OUT0 or OUT1; 20 kΩ pulldown provides safe default (disabled) at startup. |
| PE, EQ | Signal conditioning control | Binary ON/OFF control of pre-emphasis (PE) and equalization (EQ); each reduces deterministic jitter on lossy channels. |
| VCC, GND, DAP | Power & ground | Single 3.0–3.6 V supply; DAP must be soldered to PCB ground plane for thermal dissipation (θJA = 41.8°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Pin-configurable 2×2 crosspoint | Four routing modes (IN0→OUT0/OUT1, IN1→OUT0/OUT1) via SEL0/SEL1; no external logic required. |
| Transmit pre-emphasis & receive equalization | Binary PE/EQ control reduces deterministic jitter by up to 16 ps over 30″ FR-4, extending usable channel length. |
| On-chip 100 Ω termination | Eliminates eight external 100 Ω resistors, cuts board space, and minimizes return loss vs. discrete termination. |
| AEC-Q100 Grade 3 qualification | Validated for −40°C to +85°C operation with robust ESD (8 kV HBM) and latch-up immunity per automotive requirements. |
| Flow-through WQFN-16 pinout | Input/output pairs placed on opposing edges (e.g., IN0+/IN0− on pins 1/2, OUT0+/OUT0− on pins 12/11) simplifies controlled-impedance layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS crosspoint switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS25CP104QSQ/NOPB | 4×4 configuration, same 3.125 Gbps rating, identical EQ/PE controls and WQFN-24 package. | Supports four-input/four-output routing; higher pin count and larger footprint than DS25CP102QSQ/NOPB. | Select when system requires expansion beyond 2×2 topology without redesigning signal conditioning strategy. |
| SN65LVDS122DR | 2×2 LVDS repeater (not crosspoint); no EQ/PE; fixed IN0→OUT0/IN1→OUT1 routing; SOIC-8 package. | Lacks routing flexibility and signal conditioning; suited only for simple fan-out, not dynamic path selection. | Choose only for cost-sensitive, non-automotive applications where jitter budget permits and routing is static. |
Compared with DS25CP102QSQ/NOPB, DS25CP104QSQ/NOPB scales routing capacity while retaining identical signal integrity features, whereas SN65LVDS122DR sacrifices configurability and channel compensation for lower cost and smaller package-making it unsuitable for lossy or dynamically switched links.

FAQ
What is the maximum data rate supported by the DS25CP102QSQ/NOPB?
The DS25CP102QSQ/NOPB supports data rates from DC up to 3.125 Gbps, validated per PRBS-23 NRZ patterns at full temperature range. At this rate, total jitter remains ≤0.11 UIP-P with EQ and PE enabled, meeting requirements for 3G-SDI and OC-48 applications. Performance is specified with 350 mV differential input swing and 1.2 V common-mode voltage.
Does the DS25CP102QSQ/NOPB require external termination resistors?
No, the DS25CP102QSQ/NOPB integrates 100 Ω differential termination on all four LVDS inputs and outputs, eliminating the need for eight external 100 Ω resistors. This reduces component count, PCB area, and return loss variation-critical for maintaining impedance control on high-density automotive and broadcast PCBs.
How does the EQ and PE control work on the DS25CP102QSQ/NOPB?
The DS25CP102QSQ/NOPB uses two dedicated LVCMOS input pins-EQ (pin 6) and PE (pin 15)-to enable or disable receive equalization and transmit pre-emphasis, respectively. Both operate as binary controls (OFF/ON); no analog adjustment or multi-level settings are supported. Each setting is validated to reduce deterministic jitter by up to 16 ps on 30-inch FR-4 channels.
Is the DS25CP102QSQ/NOPB suitable for automotive applications?
Yes, the DS25CP102QSQ/NOPB is AEC-Q100 Grade 3 qualified (−40°C to +85°C), features 8 kV HBM ESD protection on LVDS I/O pins, and is manufactured in TI's automotive-grade process. It is explicitly targeted for automotive display applications, including instrument clusters and infotainment head units, as stated in its official datasheet and application diagrams.
What package type and thermal considerations apply to the DS25CP102QSQ/NOPB?
The DS25CP102QSQ/NOPB uses a 4 mm × 4 mm WQFN-16 package (RGH0016A) with an exposed thermal pad (DAP). For optimal thermal performance, the DAP must be soldered to a PCB ground plane using ≥4 thermal vias. Thermal resistance is θJA = 41.8°C/W; derating begins above +25°C at 23.9 mW/°C.
