Product details
Overview
DS10CP154ATSQX/NOPB from Texas Instruments is a 1.5 Gbps 4×4 LVDS crosspoint switch with adaptive equalization, integrated 100 Ω differential input/output termination, and dual-mode configuration (pin-selectable or SMBus-programmable). It supports SD/HD-SDI routing over FR-4 backplanes and balanced cables, delivers <125 ps channel-to-channel skew, and operates from −40°C to +85°C at 3.3 V supply.
For engineers reviewing the DS10CP154ATSQX/NOPB datasheet, DS10CP154ATSQX/NOPB pinout, DS10CP154ATSQX/NOPB application, or DS10CP154ATSQX/NOPB equivalent, key selection criteria include deterministic jitter ≤28 ps at 1.5 Gbps, loss-of-signal (LOS) monitoring per input, SMBus slave address programmability, and compatibility with CML/LVPECL/LVDS drivers via wide common-mode range (0.05 V to VCC−0.05 V).
Technical Context
The DS10CP154ATSQX/NOPB implements a fully differential, non-blocking 4×4 architecture enabling any input to be routed to any output simultaneously. Its internal 100 Ω termination minimizes return loss and eliminates external resistors, while SmartPWDN logic dynamically powers down unused I/O blocks based on routing configuration.
Two operational modes are supported: Pin Mode (EN_smb = 0) uses dedicated Sxx pins for per-output input selection with truth-table-based routing; SMBus Mode (EN_smb = 1) enables register-based configuration, soft power-down control, and real-time LOS status reporting via four dedicated read-only bits in the LOS register.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 1.5 Gbps - supports HD-SDI (1.485 Gbps) and dual-link SDI without retiming degradation |
| Channel Skew | ≤125 ps - ensures timing alignment across all four outputs in broadcast mode (1:4) |
| Differential Jitter | ≤28 ps peak-to-peak deterministic jitter at 1.5 Gbps - maintains eye opening for serial video links |
| Input Common-Mode Range | 0.05 V to VCC−0.05 V - enables direct DC coupling to LVPECL, CML, and LVDS drivers without level-shifting |
| Supply Current | 115–140 mA typical in quad-buffer mode - scales with active I/O count via SmartPWDN power management |
| ESD Protection | 8 kV HBM on LVDS I/O - protects against handling-induced transients in system integration |
| Operating Temperature | −40°C to +85°C - qualified for industrial and broadcast equipment environments |
Pinout & Package
DS10CP154ATSQX/NOPB is housed in a 6 mm × 6 mm WQFN-40 package (TI package code RTA0040A) with exposed thermal pad (DAP) and flow-through pinout optimized for high-speed layout. All 40 pins are defined in TI SNLS306C Rev C; no NC pins require termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0+ / IN0− to IN3+ / IN3− | Differential LVDS inputs | Four fully terminated (100 Ω) differential pairs accepting LVDS/CML/LVPECL signals; support LOS detection |
| OUT0+ / OUT0− to OUT3+ / OUT3− | Differential LVDS outputs | Four LVDS-compliant outputs with 350 mV typical VOD; internally terminated for impedance matching |
| S00/SCL, S01/SDA, S10–S21/ADDR0–3, S30–S31 | Configuration interface | Multi-function pins: select inputs per output in Pin Mode; serve as SMBus clock/data/address in SMBus Mode |
| EN_smb | Mode enable | LVCMOS input with 20 kΩ internal pull-down; high = SMBus Mode, low = Pin Mode |
| PWDN | Power-down control | Active-low LVCMOS input; functional in both modes; ORed with SoftPWDN bit D[7] in Control Register |
| VDD / GND / DAP | Power & ground | Five VDD pins (3.0–3.6 V), two GND pins, and exposed die attach pad for thermal dissipation (θJC = 3.8°C/W) |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive equalization | Compensates up to 10 dB loss at 750 MHz on FR-4 traces, extending usable reach beyond 30 cm without external EQ |
| Loss-of-signal (LOS) monitoring | Detects open-cable or disconnected-driver faults per input; status reported via SMBus LOS Register (bits D[0]–D[3]) |
| SmartPWDN power management | Automatically disables unused receivers, drivers, and logic blocks based on active routing configuration-reducing ICC by up to 40% vs. fixed-on operation |
| SMBus slave address programmability | Four ADDR pins (ADDR0–ADDR3) set LSBs of 7-bit address (101xxxxx); supports up to 16 devices on one bus |
| Flow-through WQFN layout | Input and output pins arranged opposite each other (e.g., IN0+/IN0− on left, OUT0+/OUT0− on right) minimizing trace crossovers and stubs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4×4 LVDS crosspoint switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9154ESE+ | 1.25 Gbps max rate; no integrated LOS detection; requires external 100 Ω termination resistors | Lacks SMBus configurability and adaptive equalization-suitable only for short, low-loss interconnects | Select when cost sensitivity outweighs jitter performance and diagnostic capability requirements |
| SN65LVCP22PWR | 2×2 LVDS crosspoint (not 4×4); supports up to 2 Gbps; includes integrated reclocker but no SMBus interface | Requires two devices for 4×4 functionality; lacks per-input fault monitoring and programmable addressing | Choose for higher-speed point-to-point links where full matrix routing is unnecessary |
Compared with MAX9154ESE+ and SN65LVCP22PWR, DS10CP154ATSQX/NOPB uniquely combines 1.5 Gbps 4×4 switching, on-die termination, SMBus-configurable LOS reporting, and adaptive equalization-enabling single-chip HD-SDI routing without supplemental ICs or layout-compromising external components.

FAQ
What is the maximum supported data rate for DS10CP154ATSQX/NOPB?
The DS10CP154ATSQX/NOPB is specified for operation up to 1.5 Gbps, validated with deterministic jitter ≤28 ps and total jitter ≤0.072 UIP-P at that rate. This meets SMPTE 292M HD-SDI (1.485 Gbps) and dual-link SDI timing budgets, and is tested per AC Electrical Characteristics in TI SNLS306C Rev C.
Does DS10CP154ATSQX/NOPB support DC coupling to CML or LVPECL drivers?
Yes, DS10CP154ATSQX/NOPB supports DC coupling to CML and LVPECL drivers due to its wide input common-mode range (0.05 V to VCC−0.05 V at 3.3 V supply). The internal 100 Ω differential termination eliminates need for external AC-coupling capacitors or level shifters in most implementations.
How does the loss-of-signal (LOS) function work on DS10CP154ATSQX/NOPB?
DS10CP154ATSQX/NOPB monitors differential input voltage magnitude on each of the four LVDS inputs. When VID drops below threshold (typically <100 mV), the corresponding LOS bit (D[0]–D[3]) in the SMBus-accessible LOS Register reads '0'. This feature requires EN_smb = 1 and EN_LOS bit D[6] = 1 in the Control Register.
Can DS10CP154ATSQX/NOPB be configured without using SMBus?
Yes, DS10CP154ATSQX/NOPB supports Pin Mode operation when EN_smb is held low. In this mode, four pairs of Sxx pins (e.g., S00/S01 for OUT0) directly select input sources per output using static LVCMOS logic levels-no firmware or bus communication required.
What package type and thermal characteristics apply to DS10CP154ATSQX/NOPB?
DS10CP154ATSQX/NOPB uses the WQFN-40 (RTA0040A) package: 6 mm × 6 mm body, 0.5 mm pitch, exposed thermal pad. Its thermal resistance is θJA = 26.9°C/W and θJC = 3.8°C/W, enabling operation up to 85°C ambient with standard PCB copper pour under the DAP.
