Product details
Overview
DS25CP152QSQX/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 ±8 kV HBM ESD protection on LVDS I/O pins - deployed in broadcast video routers and high-speed FR-4 interconnects.
For engineers reviewing the DS25CP152QSQX/NOPB datasheet, DS25CP152QSQX/NOPB pinout, DS25CP152QSQX/NOPB application, or DS25CP152QSQX/NOPB equivalent, key selection criteria include differential propagation delay skew (≤40 ps channel-to-channel), LVDS output compliance (350 mV typical VOD), and WQFN-16 package thermal performance (θJA = 41.8°C/W) for dense video signal routing.
Technical Context
The DS25CP152QSQX/NOPB implements a fully differential, non-blocking 2×2 architecture supporting any-input-to-any-output routing via LVCMOS SEL0/SEL1 control. Its internal 100 Ω differential terminations eliminate external resistors and reduce return loss across 0–3.125 Gbps NRZ data streams.
It accepts LVDS, CML, and LVPECL input levels via a −0.05 V to VCC−0.05 V common-mode range and delivers LVDS-compliant outputs with 250–450 mV differential voltage and <1 ps RMS random jitter at 3.125 Gbps - enabling reclocking and cable driving in SD/HD/3G HD-SDI systems without external equalizers.
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 jitter and loss compensation. |
| Differential Propagation Delay | 340–500 ps - tightly bounded timing enables synchronous multi-channel switching in broadcast infrastructure. |
| Channel-to-Channel Skew | 12–40 ps - ensures sub-bit-period alignment across both outputs for parallel video/data paths. |
| VOD (Output Differential Voltage) | 250–450 mV @ RL = 100 Ω - meets TIA/EIA-644-A LVDS standard for robust noise immunity over long traces. |
| Input Common-Mode Range | −0.05 V to VCC−0.05 V - allows DC-coupled interfacing with LVPECL (VCC = 3.3 V) and CML drivers without level shifters. |
| ESD Protection | ±8 kV HBM on LVDS I/O - safeguards against electrostatic discharge during board handling and system integration. |
| Supply Current | 64–77 mA active, 23–29 mA disabled - enables low-power state management in multi-switch router cards. |
Pinout & Package
DS25CP152QSQX/NOPB uses a 4 mm × 4 mm WQFN-16 package (RGH0016A) with exposed thermal pad (DAP) for enhanced heat dissipation in compact video routing modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0+, IN0− | Differential LVDS Input 0 | Accepts high-speed serial video/data; internally terminated 100 Ω; supports LVDS/CML/LVPECL DC coupling. |
| IN1+, IN1− | Differential LVDS Input 1 | Second independent input path; identical termination and interface capability as IN0. |
| OUT0+, OUT0− | Differential LVDS Output 0 | LVDS-compliant output with 250–450 mV VOD; enabled/disabled via EN0; routed per SEL0/SEL1 logic. |
| OUT1+, OUT1− | Differential LVDS Output 1 | Independent output path with same electrical specs as OUT0; supports broadcast or crosspoint modes. |
| SEL0, SEL1 | LVCMOS Switch Configuration | 2-bit binary control (00–11) selects input routing per truth table; 20 kΩ pulldown ensures default state. |
| EN0, EN1 | LVCMOS Output Enable | Individual enable/disable of each output; 20 kΩ pulldown prevents floating; tOFF = 5–12 ns fast disable. |
| VCC | Power Supply | +3.0 to +3.6 V supply; supports 3.3 V nominal operation with 77 mA max ICC at 3.125 Gbps. |
| GND, DAP | Ground / Thermal Pad | Primary ground pins plus exposed DAP - must be soldered to PCB ground plane for thermal and EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip 100 Ω differential terminations | Eliminates 8 external resistors per device, reduces PCB area by ≥12 mm², and improves impedance matching on FR-4 backplanes. |
| Pin-configurable non-blocking crosspoint | SEL0/SEL1 bits support four routing states (IN0→OUT0/OUT1, IN1→OUT0/OUT1) without reconfiguration delay or arbitration logic. |
| Low-skew, low-jitter signal path | ≤40 ps channel-to-channel skew and ≤1 ps RMS random jitter preserve eye opening for 3G HD-SDI signals after 2″ FR-4 stripline. |
| Wide input common-mode range | Supports direct DC coupling to LVPECL (VCC = 3.3 V) and CML drivers without AC coupling capacitors or bias networks. |
| LVDS output compliance with fast enable/disable | tON = 7–20 μs and tOFF = 5–12 ns allow dynamic power gating in multi-stage video distribution systems. |

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+ | Slower max rate (2.5 Gbps); no integrated input termination; requires external 100 Ω resistors. | Suitable for HD-SDI only (1.485 Gbps); not recommended for 3G HD-SDI due to bandwidth limitation. | Select when cost sensitivity outweighs board space and 3G HD-SDI support requirements. |
| SN65LVCP22PWR | Higher supply current (105 mA); no SEL/EN pins - fixed routing; no internal termination on inputs. | Designed for point-to-point repeater use, not configurable crosspoint routing in multi-source systems. | Choose only for simple repeater applications where pin configuration and low power are not required. |
Compared with MAX9152ESE+ and SN65LVCP22PWR, DS25CP152QSQX/NOPB uniquely combines 3.125 Gbps bandwidth, pin-configurable routing, and on-die 100 Ω terminations - making it the only option qualified for compact, high-density 3G HD-SDI router designs requiring zero external termination components.

FAQ
What is the maximum data rate supported by the DS25CP152QSQX/NOPB?
The DS25CP152QSQX/NOPB supports DC to 3.125 Gbps operation, validated for 3G HD-SDI (2.97 Gbps) with margin. Its AC specifications - including ≤1 ps RMS random jitter and ≤40 ps channel-to-channel skew - are guaranteed at this rate, ensuring reliable eye opening after FR-4 trace losses. The device maintains LVDS compliance across the full range without external equalization.
Does the DS25CP152QSQX/NOPB require external termination resistors?
No, the DS25CP152QSQX/NOPB integrates 100 Ω differential terminations on all four LVDS I/O pairs (IN0/IN1/OUT0/OUT1). This eliminates eight external 100 Ω resistors, reduces PCB footprint by ≥12 mm², lowers return loss, and simplifies layout - especially critical in high-density broadcast router cards where space and signal integrity are constrained.
How does the DS25CP152QSQX/NOPB handle different input signal standards like LVPECL or CML?
The DS25CP152QSQX/NOPB accepts LVPECL, CML, and LVDS inputs via its wide −0.05 V to VCC−0.05 V common-mode range. It supports direct DC coupling without level shifters or AC coupling capacitors - confirmed by TI's Figure 8–10 application schematics. Input differential voltage must remain within 0–1 V, and internal 100 Ω termination ensures proper loading for all three standards.
What is the function of the SEL0 and SEL1 pins on the DS25CP152QSQX/NOPB?
SEL0 and SEL1 are LVCMOS control inputs that configure the 2×2 crosspoint routing matrix. As defined in Table 1 of the DS25CP152QSQX/NOPB datasheet, they select which input (IN0 or IN1) drives each output (OUT0 and OUT1) in four possible combinations (00–11). Each pin has an internal 20 kΩ pulldown, ensuring a known default state (IN0→OUT0/OUT1) at power-up.
Can the DS25CP152QSQX/NOPB outputs be disabled independently?
Yes, the DS25CP152QSQX/NOPB provides independent output enable control via EN0 and EN1 pins. Per Table 2, setting EN0 = low disables OUT0 while leaving OUT1 operational if EN1 = high - enabling dynamic power management in multi-output systems. Disable time is specified at 5–12 ns, allowing fast response to routing or power-state commands without signal glitches.
