Product details
Overview
DS10CP154ATSQ/NOPB from Texas Instruments is a 1.5 Gbps 4×4 LVDS crosspoint switch with integrated 100 Ω differential input/output termination, adaptive equalization for SD/HD video routing, and dual-mode configuration (pin-selectable or SMBus-programmable). It supports DC-coupled interfacing with LVPECL, CML, and LVDS drivers, and delivers <125 ps channel-to-channel skew in broadcast mode for SDI router backplanes.
For engineers reviewing the DS10CP154ATSQ/NOPB datasheet, DS10CP154ATSQ/NOPB pinout, DS10CP154ATSQ/NOPB application, or DS10CP154ATSQ/NOPB equivalent, key selection criteria include its 1.5 Gbps bandwidth, on-chip LOS detection per input, SMBus-addressable slave capability (7-bit address with ADDR0–ADDR3), low-power SmartPWDN architecture, and WQFN-40 package with flow-through layout for high-density PCB routing.
Technical Context
The DS10CP154ATSQ/NOPB implements a fully differential, non-blocking 4×4 LVDS switching matrix with two distinct configuration modes: Pin Mode (EN_smb = 0) using dedicated Sxx select pins per output, and SMBus Mode (EN_smb = 1) enabling register-based routing, soft power-down (SoftPWDN), and real-time loss-of-signal monitoring via the LOS register. Each input and output pair is internally terminated to 100 Ω, eliminating external resistors and minimizing return loss.
Its AC performance targets broadcast-grade video infrastructure: deterministic jitter ≤28 ps peak-to-peak at 1.5 Gbps, random jitter ≤1.0 ps RMS at 750 MHz, and propagation delay skew ≤125 ps across all four outputs when routing one input to all outputs. The device operates from 3.0 V to 3.6 V over −40°C to +85°C and features 8 kV HBM ESD protection on all LVDS I/O pins.
Key Specifications

Pinout & Package
DS10CP154ATSQ/NOPB uses a 6 mm × 6 mm WQFN-40 package (TI package code RTA0040A) with exposed thermal pad (DAP) and flow-through pin arrangement optimized for controlled-impedance FR-4 backplane routing. Pin numbering follows standard TI WQFN convention with GND and VDD distributed across perimeter for low-noise power delivery.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0+ / IN0− to IN3+ / IN3− | Differential LVDS inputs | Four fully differential, 100 Ω internally terminated inputs accepting LVDS/CML/LVPECL signals |
| OUT0+ / OUT0− to OUT3+ / OUT3− | Differential LVDS outputs | Four LVDS-compliant outputs with 350 mV typical differential swing and 100 Ω internal termination |
| S00/SCL, S01/SDA, S10/ADDR0–S21/ADDR3, S30/S31 | Configurable I/O | Function multiplexed: pin-select control (Sxx) in EN_smb = 0 mode; SMBus clock/data/address in EN_smb = 1 mode |
| EN_smb | Mode select input | LVCMOS input with 20 kΩ internal pull-down; high = SMBus mode, low = pin-configuration mode |
| PWDN | Power-down control | Active-low LVCMOS input; asserts hardware power-down regardless of EN_smb state |
| VDD (pins 3, 8, 15, 25, 30) | Power supply | Five distributed 3.3 V supply pins reduce IR drop and improve PSRR across high-speed operation |
| GND (pins 16, DAP) | Ground reference | Primary ground pin + exposed die-attach pad for thermal conduction and low-inductance return path |
Key Features

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9154ESE+ | 4×4 LVDS crosspoint with 1.25 Gbps max rate; no SMBus interface; fixed pin-configuration only | Lacks LOS monitoring and dynamic power management; requires external 100 Ω terminations | Choose for cost-sensitive, static-routing systems where SMBus control and fault reporting are unnecessary |
| SN65LVCP22PWR | 2×2 LVDS crosspoint with 2 Gbps rating; single-supply 3.3 V; no integrated termination or LOS circuitry | Half the port count; higher bandwidth but no built-in diagnostics or power optimization | Prefer when scaling to multi-device topologies with discrete routing control and external termination budget |

FAQ
What is the maximum data rate supported by DS10CP154ATSQ/NOPB?
The DS10CP154ATSQ/NOPB supports a maximum data rate of 1.5 Gbps, verified across temperature and voltage ranges. This enables full compliance with SMPTE 292M HD-SDI (1.485 Gbps) and SMPTE 424M 3G-SDI (2.97 Gbps) when used in dual-lane configurations. Measured deterministic jitter remains ≤28 ps peak-to-peak at 1.5 Gbps, ensuring reliable eye opening in real-world FR-4 backplane environments.
Does DS10CP154ATSQ/NOPB require external termination resistors?
No, DS10CP154ATSQ/NOPB does not require external termination resistors. It integrates 100 Ω differential termination on all four inputs and four outputs, minimizing board space, reducing component count by eight resistors, and improving return loss performance to >20 dB across 100 MHz–1.5 GHz. This eliminates layout sensitivity and simplifies impedance matching for balanced cable and FR-4 trace interfaces.
How does the loss-of-signal (LOS) detection work on DS10CP154ATSQ/NOPB?
The DS10CP154ATSQ/NOPB implements per-input LOS detection that monitors differential input voltage amplitude and flags open-cable conditions. In SMBus Mode, status is reported in the read-only LOS register (address 0x04), where bits D[3:0] indicate signal presence (1) or open-fault (0) for IN3–IN0 respectively. In Pin Mode, LOS functionality is disabled-no hardware output or register access is available.
Can DS10CP154ATSQ/NOPB interface directly with LVPECL drivers?
Yes, DS10CP154ATSQ/NOPB can interface directly with LVPECL drivers via DC coupling. Its wide input common-mode range (VCC − 0.05 V to 0.05 V) accommodates LVPECL's typical ~1.6 V common-mode level without external biasing networks. The internal 100 Ω termination provides proper loading, and the device's 1.0 V differential input voltage limit ensures safe operation with standard LVPECL output swings.
What package type and thermal characteristics does DS10CP154ATSQ/NOPB use?
DS10CP154ATSQ/NOPB uses a 6 mm × 6 mm WQFN-40 package (TI package code RTA0040A) with exposed thermal pad (DAP). It has a junction-to-ambient thermal resistance (θJA) of 26.9°C/W and junction-to-case (θJC) of 3.8°C/W. The package is rated MSL Level-3 (260°C peak reflow, 168-hour floor life) and supports continuous operation at 85°C ambient with appropriate PCB copper pour under the DAP.
