Product details
Overview
DS25CP152TSQX/NOPB from Texas Instruments is a 3.125 Gbps 2×2 LVDS crosspoint switch with integrated 100 Ω input/output terminations, adaptive equalization for SD/HD/3G HD-SDI backplane routing, and <40 ps channel-to-channel skew. It operates from 3.0–3.6 V at −40°C to +85°C and supports LVDS/CML/LVPECL input compatibility in broadcast or point-to-point configurations for video infrastructure systems.
For engineers reviewing the DS25CP152TSQX/NOPB datasheet, DS25CP152TSQX/NOPB pinout, DS25CP152TSQX/NOPB application, or DS25CP152TSQX/NOPB equivalent, this page delivers verified electrical parameters, functional truth tables, thermal resistance (θJA = 41.8°C/W), jitter performance (tTJ2 ≤ 0.09 UIP-P @ 3.125 Gbps), and WQFN-16 package layout guidance - all directly extracted from TI SNLS274D Rev D.
Technical Context
The DS25CP152TSQX/NOPB implements a fully differential, non-blocking 2×2 switching matrix with independent LVCMOS control of SEL0/SEL1 (switch configuration) and EN0/EN1 (output enable). Its internal 100 Ω differential terminations eliminate external resistors and reduce return loss on FR-4 backplanes up to 2 inches at 3.125 Gbps.
It features adaptive equalization optimized for SD/HD/3G HD-SDI signal integrity over lossy media, with deterministic jitter ≤19 ps peak-to-peak and random jitter ≤1 ps RMS at 3.125 Gbps. The device uses a flow-through pinout in a 4 mm × 4 mm WQFN-16 package with exposed thermal pad (DAP) for enhanced thermal dissipation (θJC = 6.9°C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 3.125 Gbps - supports full 3G HD-SDI (2.97 Gbps) with margin for clock recovery and jitter tolerance. |
| Propagation Delay | 340–500 ps - tightly bounded low-latency path critical for synchronous video routing and reclocking. |
| Channel Skew | ≤40 ps - ensures timing alignment between OUT0 and OUT1 outputs in broadcast mode for parallel data paths. |
| Differential Output Voltage | 250–450 mV - meets LVDS standard compliance (ANSI/TIA/EIA-644) for robust noise immunity and receiver compatibility. |
| Supply Current | 64–77 mA active / 23–29 mA disabled - enables dynamic power management via EN0/EN1 without signal interruption. |
| ESD Protection | ≥8 kV HBM on LVDS I/O - safeguards against electrostatic discharge during board handling and system integration. |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade video equipment deployed in broadcast vans, OB trucks, and studio routers. |
Pinout & Package
DS25CP152TSQX/NOPB is housed in a 4 mm × 4 mm WQFN-16 package (TI RGH0016A) with wettable flanks and an exposed thermal pad (DAP) requiring solder connection to PCB ground for optimal thermal performance (θJC = 6.9°C/W). Pin 1 is located in Quadrant Q1 per tape-and-reel orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0+, IN0− | Differential LVDS Input | Accepts LVDS/CML/LVPECL signals; internally terminated with 100 Ω; wide common-mode range (0.05 V to VCC−0.05 V). |
| IN1+, IN1− | Differential LVDS Input | Second independent high-speed input pair with identical termination and interface flexibility as IN0. |
| OUT0+, OUT0− | Differential LVDS Output | LVDS-compliant output (250–450 mV swing); enabled/disabled independently via EN0; 100 Ω internal termination. |
| OUT1+, OUT1− | Differential LVDS Output | Second LVDS output with matched skew and jitter performance to OUT0; supports simultaneous or isolated routing. |
| SEL0, SEL1 | LVCMOS Configuration | Set crosspoint routing (IN0/IN1 → OUT0/OUT1) per truth table; 20 kΩ pulldown ensures default state on power-up. |
| EN0, EN1 | LVCMOS Output Enable | Individually disable OUT0 or OUT1 to reduce power or isolate downstream receivers without affecting signal path integrity. |
| VCC, GND, DAP | Power & Ground | Single 3.3 V supply (3.0–3.6 V); DAP must be soldered to PCB ground plane for thermal and EMI performance. |
| NC (Pins 6, 15) | No Connect | Unbonded pins; must remain unconnected per TI design - no routing or grounding permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential non-blocking architecture | Enables any input to connect to any output (or both) simultaneously - essential for flexible SDI router card designs with redundant paths. |
| On-chip 100 Ω differential terminations | Eliminates 8 external resistors per device, reduces PCB area by ≥12 mm², and improves impedance matching on dense backplanes. |
| Adaptive equalization for SD/HD/3G HD | Compensates for frequency-dependent loss in FR-4 striplines up to 2″ length at 3.125 Gbps - validated in TI Figure 12–13 eye diagrams. |
| Low-jitter reclocking + cable driving | Delivers tTJ2 ≤ 0.09 UIP-P at 3.125 Gbps - meets SMPTE 424M jitter budget for 3G HD-SDI transmission over coaxial or balanced cables. |
| Flow-through pinout in WQFN-16 | Minimizes trace crossovers and stubs; simplifies high-speed layout with straight-in/straight-out routing for IN/OUT pairs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2×2 LVDS crosspoint switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9152ESE+ | 2.5 Gbps max data rate; no adaptive equalization; SOIC-16 package (larger footprint, higher inductance). | Limited to HD-SDI (1.485 Gbps); unsuitable for 3G HD-SDI backplane compensation or >2″ FR-4 traces. | Select only if operating below 2.5 Gbps and board space permits SOIC; verify jitter budget separately. |
| SN65LVDS250PW | 2×2 LVDS repeater (not crosspoint); fixed IN0→OUT0/IN1→OUT1 mapping; no SEL/EN control logic. | Cannot route IN0→OUT1 or support broadcast mode; lacks configuration flexibility required for router cards. | Use only for simple duplication or signal regeneration where switching logic is handled upstream. |
Compared with MAX9152ESE+ and SN65LVDS250PW, DS25CP152TSQX/NOPB uniquely combines 3.125 Gbps operation, adaptive equalization, pin-configurable routing, and ultra-low skew in a space-saving WQFN package - making it the only option qualified for 3G HD-SDI router backplanes per SMPTE 424M.

FAQ
What is the maximum supported data rate for DS25CP152TSQX/NOPB?
The DS25CP152TSQX/NOPB is specified for DC to 3.125 Gbps operation, with guaranteed AC performance including jitter and skew metrics at that rate. It is fully compliant with SMPTE 424M for 3G HD-SDI (2.97 Gbps) applications and provides margin for system-level timing budgets. Operation beyond 3.125 Gbps is not characterized or supported.
Does DS25CP152TSQX/NOPB require external termination resistors?
No. DS25CP152TSQX/NOPB integrates 100 Ω differential terminations on all four LVDS I/O pairs (IN0±, IN1±, OUT0±, OUT1±), eliminating the need for eight discrete 100 Ω resistors. This reduces PCB area, component count, and potential impedance mismatches - confirmed in TI SNLS274D Section "On-Chip 100Ω Input and Output Terminations".
Can DS25CP152TSQX/NOPB accept LVPECL or CML inputs?
Yes. DS25CP152TSQX/NOPB supports LVPECL and CML input levels due to its wide input common-mode voltage range (0.05 V to VCC−0.05 V) and internal 100 Ω termination. TI Application Figures 9 and 10 explicitly show DC-coupled interfaces to both LVPECL and CML drivers, confirming interoperability without level-shifting circuitry.
How is thermal management handled for DS25CP152TSQX/NOPB?
DS25CP152TSQX/NOPB uses a WQFN-16 package with an exposed thermal pad (DAP, Pin 5). TI requires this pad to be soldered to a PCB ground plane to achieve θJC = 6.9°C/W and maintain junction temperature within limits. The datasheet specifies 2.99 W max power dissipation at 25°C with 23.9 mW/°C derating above that temperature.
What is the function of SEL0 and SEL1 pins on DS25CP152TSQX/NOPB?
SEL0 and SEL1 are LVCMOS control inputs that configure the crosspoint routing matrix per Table 1 in the DS25CP152TSQX/NOPB datasheet. They determine which input (IN0 or IN1) connects to OUT0 and OUT1 - supporting four modes: IN0→both outputs, IN0→OUT0/IN1→OUT1, IN1→OUT0/IN0→OUT1, or IN1→both outputs. Each pin has an internal 20 kΩ pulldown resistor.
