Product details
Overview
DS10CP154TSQ/NOPB from Texas Instruments (formerly National Semiconductor) is a 1.5 Gbps 4×4 LVDS crosspoint switch optimized for high-speed signal routing over FR-4 backplanes and balanced cables. It features fully differential non-blocking architecture, on-chip 100 Ω input/output termination, and dual configuration modes (pin-selectable or SMBus-controlled). Used in SD/HD-SDI routers for lossless video signal switching.
For engineers reviewing the DS10CP154TSQ/NOPB datasheet, DS10CP154TSQ/NOPB pinout, DS10CP154TSQ/NOPB application, or DS10CP154TSQ/NOPB equivalent, key selection criteria include deterministic jitter at 1.5 Gbps (≤28 ps p-p), channel-to-channel skew (≤125 ps), SMBus slave address programmability, and DC-coupled compatibility with LVPECL/CML/LVDS drivers.
Technical Context
The DS10CP154TSQ/NOPB implements a non-blocking 4×4 LVDS crosspoint matrix with independent per-output routing control. Its dual-mode operation-pin-configurable (EN_smb = 0) or SMBus-programmable (EN_smb = 1)-enables flexible integration in both fixed-function and dynamically reconfigurable systems.
It integrates loss-of-signal (LOS) monitoring per input channel, accessible only via SMBus register reads (LOS Register, Address 0x04), and supports SmartPWDN power optimization that disables unused I/O blocks based on active routing paths. Input common mode range (0.05 V to VCC − 0.05 V) enables direct DC coupling to LVPECL, CML, and LVDS sources without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Signal Rate | DC to 1.5 Gbps - supports SMPTE 292M HD-SDI (1.485 Gbps) and legacy SD-SDI (270 Mbps) without retiming. |
| Differential Skew | Channel-to-channel skew ≤125 ps - ensures timing alignment across all four outputs in broadcast mode (1:4). |
| Jitter Performance | Deterministic jitter ≤28 ps p-p at 1.5 Gbps - meets stringent eye-opening requirements for serial digital video links. |
| Input Termination | On-chip 100 Ω differential termination - eliminates external resistors, reduces board space, and minimizes insertion loss. |
| ESD Protection | 8 kV HBM on LVDS I/O pins - protects against electrostatic discharge during handling and system integration. |
| Supply Voltage | 3.0 V to 3.6 V (typ. 3.3 V) - compatible with standard LVDS logic rails and industrial power domains. |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade embedded video infrastructure equipment. |
Pinout & Package
DS10CP154TSQ/NOPB uses a 40-pin LLP (Leadless Leadframe Package) with 6 mm × 6 mm footprint and exposed thermal pad (DAP). Pin layout follows flow-through routing for minimal trace stubs and optimal signal integrity on high-speed PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0+ / IN0− to IN3+ / IN3− (Pins 1–2, 4–5, 6–7, 9–10) | Differential LVDS inputs | Accept LVDS/CML/LVPECL signals; internally terminated 100 Ω; support DC coupling without external biasing. |
| OUT0+ / OUT0− to OUT3+ / OUT3− (Pins 21–22, 23–24, 26–27, 28–29) | Differential LVDS outputs | LVDS-compliant outputs (250–450 mV diff swing); 100 Ω on-chip termination; drive standard 100 Ω differential loads. |
| EN_smb (Pin 17) | SMBus mode enable | Pull-down internal 20 kΩ; logic high activates SMBus interface and disables pin-select function for S00/S01, S10/S11, etc. |
| S00/SCL & S01/SDA (Pins 37, 36) | Configurable dual-role pins | In SMBus mode: SCL clock input and SDA bidirectional data; in pin mode: input select for OUT0. |
| PWDN (Pin 38) | Hardware power-down control | Active-low; forces full device shutdown (except SMBus/LOS circuitry) when EN_smb = 0; ORed with SoftPWDN bit D[7] when EN_smb = 1. |
| VDD (Pins 3, 8, 15, 25, 30) & GND (Pins 16, DAP) | Power distribution network | Multiple VDD/GND pins minimize supply impedance; exposed DAP enhances thermal dissipation (θJC = 3.8°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Non-blocking 4×4 LVDS crosspoint | Any input can be routed to any output simultaneously - enables dynamic reconfiguration of video/data paths without blocking. |
| SMBus-based LOS monitoring | Per-input open-cable detection reported via read-only LOS Register (Address 0x04) - enables system-level fault isolation in SDI routers. |
| SmartPWDN power optimization | Automatically powers down unused I/O blocks and logic based on active routing configuration - reduces ICC by up to 40% in partial-use scenarios. |
| DC-coupled multi-standard input interface | Wide common-mode range (0.05 V to VCC − 0.05 V) supports direct connection to LVPECL, CML, and LVDS drivers - eliminates AC-coupling capacitors and bias networks. |
| Flow-through pinout in LLP-40 package | Input pins on left side, outputs on right side, control pins on top/bottom - simplifies layer stackup and minimizes crosstalk in dense HD-SDI PCB layouts. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS crosspoint switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS10CP154TSQX/NOPB | Same die, tape-and-reel packaging variant (no functional difference); identical electrical specs and pinout. | No change in system integration; used for automated SMT assembly where reel format required. | Select DS10CP154TSQX/NOPB for volume production with pick-and-place machines; DS10CP154TSQ/NOPB is tray-packaged for prototyping and low-volume builds. |
| DS10CP154A | Enhanced SMBus implementation supporting multi-slave bus sharing; adds arbitration and timeout recovery not present in DS10CP154TSQ/NOPB. | Required when multiple crosspoint devices share one SMBus segment; DS10CP154TSQ/NOPB is limited to point-to-point SMBus only. | Choose DS10CP154A for centralized control architectures with ≥2 crosspoints on same SMBus; DS10CP154TSQ/NOPB suffices for standalone or isolated SMBus nodes. |
Compared with DS10CP154TSQ/NOPB, DS10CP154TSQX/NOPB offers identical performance in a different packaging format, while DS10CP154A extends SMBus capability to shared-bus environments - making it essential for scalable multi-device control but unnecessary for single-switch deployments.

FAQ
What is the maximum data rate supported by the DS10CP154TSQ/NOPB?
The DS10CP154TSQ/NOPB supports data rates from DC up to 1.5 Gbps, verified by AC electrical characterization including tTJ4 = 0.072 UIP-P at 1.5 Gbps. This enables compliance with SMPTE 292M HD-SDI (1.485 Gbps) and legacy SD-SDI (270 Mbps) standards without signal degradation.
Does the DS10CP154TSQ/NOPB support DC-coupled inputs from LVPECL sources?
Yes, the DS10CP154TSQ/NOPB supports DC-coupled LVPECL inputs due to its wide input common mode voltage range of 0.05 V to VCC − 0.05 V (typically 3.25 V at VCC = 3.3 V). Figure 30006633 in the official datasheet confirms direct interface without level-shifting components.
How is loss-of-signal (LOS) detection implemented in the DS10CP154TSQ/NOPB?
LOS detection in the DS10CP154TSQ/NOPB is implemented per input channel using internal comparators and is accessible only via SMBus register reads (LOS Register at address 0x04). Each bit (D[0]–D[3]) reports open-cable status; no dedicated LOS output pins exist in pin-mode operation.
What is the thermal performance of the DS10CP154TSQ/NOPB package?
The DS10CP154TSQ/NOPB uses an LLP-40 package with exposed die attach pad (DAP). Its thermal resistance is θJA = 26.9°C/W and θJC = 3.8°C/W, enabling reliable operation at full 1.5 Gbps with ambient temperatures up to +85°C when mounted on 2 oz copper with 4 thermal vias under the DAP.
Can the DS10CP154TSQ/NOPB be used in pin-mode and SMBus-mode simultaneously?
No, the DS10CP154TSQ/NOPB operates exclusively in one mode at a time, selected by the EN_smb pin state: logic low (0) enables pin-mode configuration using S00/S01, S10/S11, etc.; logic high (1) enables SMBus-mode, repurposing those pins as SCL/SDA and ADDR0–ADDR3. Mixed-mode operation is not supported.
