Product details
Overview
DS10CP154TSQX/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-programmable). Used in SD/HD-SDI routers for real-time video signal switching.
For engineers reviewing the DS10CP154TSQX/NOPB datasheet, DS10CP154TSQX/NOPB pinout, DS10CP154TSQX/NOPB application, or DS10CP154TSQX/NOPB equivalent, key selection criteria include deterministic jitter at 1.5 Gbps (≤28 ps), channel-to-channel skew (≤125 ps), SMBus slave address configurability, LOS fault monitoring capability, and support for DC-coupled CML/LVPECL/LVDS inputs.
Technical Context
The DS10CP154TSQX/NOPB implements a fully differential, non-blocking 4×4 switch matrix with independent input routing per output. Its dual-mode control-hardware pin-select (EN_smb = 0) or SMBus register-based (EN_smb = 1)-enables flexible integration in both fixed-configuration and dynamically reconfigurable systems.
It integrates loss-of-signal (LOS) detection circuitry per input channel, reporting open-cable faults via SMBus register reads. Input common mode range (0.05 V to VCC − 0.05 V) supports DC-coupled interfacing with LVDS, CML, and LVPECL drivers; outputs are strictly LVDS-compliant with 250–450 mV differential swing and 100 Ω internal termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Architecture | 4×4 non-blocking LVDS crosspoint with independent input selection per output |
| Max Data Rate | 1.5 Gbps per channel - supports HD-SDI (1.485 Gbps) and SMPTE 292M |
| Deterministic Jitter (1.5 Gbps) | 12–28 ps peak-to-peak - ensures reliable eye opening in serial video links |
| Channel-to-Channel Skew | ≤125 ps - maintains timing alignment across routed video/data lanes |
| Input Common Mode Range | 0.05 V to VCC − 0.05 V - enables direct DC coupling to CML/LVPECL without level shifters |
| On-Chip Termination | 100 Ω differential termination on all 4 inputs and 4 outputs - eliminates 16 external resistors |
| ESD Protection | ≥8 kV HBM on LVDS I/O - protects against handling and system-level ESD events |
| Supply Voltage | 3.0–3.6 V - compatible with standard 3.3 V logic rails and industrial power domains |
Pinout & Package
DS10CP154TSQX/NOPB uses a 40-pin LLP (Leadless Leadframe Package) with 6 mm × 6 mm footprint and exposed thermal pad (DAP). Pinout follows flow-through layout to simplify PCB routing on dense high-speed boards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0+ / IN0− to IN3+ / IN3− (Pins 1–2, 4–5, 6–7, 9–10) | Differential LVDS inputs | Accepts LVDS/CML/LVPECL signals; internally terminated 100 Ω; supports LOS monitoring |
| OUT0+ / OUT0− to OUT3+ / OUT3− (Pins 21–22, 23–24, 26–27, 28–29) | Differential LVDS outputs | LVDS-compliant outputs (250–450 mV swing); 100 Ω internal termination; rail-to-rail drive into 100 Ω loads |
| EN_smb (Pin 17) | SMBus mode enable | Pull-down enabled; logic high selects SMBus configuration mode; resets registers on toggle |
| S00/SCL & S01/SDA (Pins 36–37) | Mode-shared pins | In pin mode: input select for OUT0; in SMBus mode: clock/data interface (10–100 kHz) |
| S10/ADDR0 to S21/ADDR3 (Pins 32–35) | Mode-shared address/select | In pin mode: input select for OUT1/OUT2; in SMBus mode: user-set 4-bit slave address (ADDR0–ADDR3) |
| S30/S31 (Pins 13–14) | Pin-mode select only | Select input for OUT3 in pin mode; no function in SMBus mode - must tie to logic high or low |
| PWDN (Pin 38) | Power-down control | Active-low; powers down analog core while retaining SMBus/LOS functionality when EN_smb = 1 |
| VDD (Pins 3, 8, 15, 25, 30) | Power supply | Five distributed 3.3 V supply pins reduce IR drop and improve PSRR |
| GND & DAP (Pins 16, DAP) | Ground reference | Thermal pad (DAP) must be soldered to PCB ground plane for thermal management (θJC = 3.8°C/W) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4×4 LVDS crosspoint switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS10CP154A | Supports multi-slave SMBus bus sharing; identical pinout and electrical specs | Required when multiple crosspoint devices share one SMBus; DS10CP154TSQX/NOPB is limited to point-to-point SMBus | Select DS10CP154A for systems requiring scalable SMBus topology with >1 crosspoint per bus |
| DS25CP104 | 4×4 LVDS crosspoint with identical 1.5 Gbps rating but lacks LOS monitoring and SMBus interface | Pin-mode only; no firmware-accessible fault reporting; simpler control but less diagnostic capability | Choose DS25CP104 where SMBus control and open-cable detection are unnecessary and cost is prioritized |
Compared with DS10CP154A, DS10CP154TSQX/NOPB offers identical performance but restricts SMBus to point-to-point use; versus DS25CP104, it adds LOS monitoring and SMBus programmability at the cost of slightly higher complexity - ideal for diagnostic-aware broadcast and test systems.

FAQ
What is the maximum data rate supported by the DS10CP154TSQX/NOPB?
The DS10CP154TSQX/NOPB supports a maximum data rate of 1.5 Gbps per channel. This specification is validated across temperature (−40°C to +85°C) and supply voltage (3.0 V to 3.6 V) ranges, and meets SMPTE 292M requirements for HD-SDI video transport. Deterministic jitter remains ≤28 ps at this rate, ensuring reliable signal integrity in real-world backplane and cable environments.
Does the DS10CP154TSQX/NOPB support DC-coupled inputs from LVPECL drivers?
Yes, the DS10CP154TSQX/NOPB supports DC-coupled LVPECL inputs due to its wide input common mode range of 0.05 V to VCC − 0.05 V. When powered at 3.3 V, this spans approximately 0.05 V to 3.25 V - sufficient to accommodate typical LVPECL common mode voltages (~1.8 V to 2.2 V). No external level-shifting circuitry is required, simplifying interconnect design and reducing component count.
How does the loss-of-signal (LOS) monitoring work on the DS10CP154TSQX/NOPB?
The DS10CP154TSQX/NOPB provides per-input LOS detection that flags open-cable or disconnected-source conditions. LOS status is reported exclusively via the SMBus interface in the read-only LOS register (address 0x04), where bits D[3:0] indicate signal presence (1) or open-fault (0) on IN3–IN0. This feature requires EN_smb = 1 and EN_LOS bit (Control Register D[6]) set to 1; it is unavailable in pin-mode operation.
What is the thermal pad (DAP) connection requirement for the DS10CP154TSQX/NOPB?
The DS10CP154TSQX/NOPB includes an exposed die attach pad (DAP) at Pin 16 location, which serves as the primary thermal path. This pad must be soldered to a solid copper ground plane on the PCB using ≥6 thermal vias (0.3 mm diameter) to achieve the specified θJC of 3.8°C/W. Failure to properly connect the DAP risks junction temperature exceeding 150°C under full 140 mA ICC3 load, potentially triggering thermal shutdown or reliability degradation.
Can the DS10CP154TSQX/NOPB be used in systems with multiple SMBus slave devices on the same bus?
No - the DS10CP154TSQX/NOPB supports only point-to-point SMBus connections between one master and itself. Sharing the SMBus with other slave devices will cause communication conflicts due to lack of arbitration support and fixed timing behavior. For multi-device SMBus topologies, TI recommends the DS10CP154A, which is functionally identical but certified for multi-slave bus operation per SMBus 2.0 specifications.
