Product details
Overview
DS25CP102TSQX/NOPB from Texas Instruments is a 3.125 Gbps 2×2 LVDS crosspoint switch with pin-selectable transmit pre-emphasis and receive equalization, internally terminated with 100 Ω differential input/output resistors, operating from 3.0 V to 3.6 V supply, and housed in a 4 mm × 4 mm WQFN-16 package for high-density routing in SD/HD/3G-SDI routers and OC-48 backplane interfaces.
For engineers reviewing the DS25CP102TSQX/NOPB datasheet, DS25CP102TSQX/NOPB pinout, DS25CP102TSQX/NOPB application, or DS25CP102TSQX/NOPB equivalent, this page delivers verified electrical specs (e.g., 350 mV typical VOD, 25 ps max channel-to-channel skew), functional truth tables (SEL/EN/PE/EQ control logic), thermal resistance (θJA = 41.8°C/W), ESD rating (8 kV HBM), and real-world jitter performance (≤0.16 UIP-P at 3.125 Gbps with EQ+PE enabled).
Technical Context
The DS25CP102TSQX/NOPB implements a fully differential, non-blocking 2×2 LVDS architecture with independent EN0/EN1 output enables and SEL0/SEL1 switch configuration pins, supporting broadcast (IN0→OUT0+OUT1) and cross (IN0→OUT1, IN1→OUT0) modes per Table 1. Its signal path includes on-die 100 Ω termination on all four differential I/O pairs, eliminating external resistors and minimizing board space.
Transmit pre-emphasis (PE pin) and receive equalization (EQ pin) each offer two discrete levels (Off/On), enabling adaptive compensation for lossy FR-4 striplines up to 60 inches - validated via test channels A–F with insertion loss from −1.2 dB (10″) to −17.0 dB (60″) at 1.56 GHz - while maintaining deterministic jitter ≤21 ps peak-to-peak under PRBS-23 NRZ at 3.125 Gbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 3.125 Gbps - supports OC-48/STM-16 line rates and 3G-SDI (2.97 Gbps) without retiming. |
| Differential Output Voltage (VOD) | 250–450 mV - ensures robust LVDS compliance across process/voltage/temperature, enabling direct interface to standard LVDS receivers. |
| Channel-to-Channel Skew (tSKD2) | 12–25 ps - guarantees tight timing alignment between OUT0 and OUT1 outputs in broadcast mode, critical for parallel clock/data distribution. |
| Input Common Mode Range | 0.05 V to VCC−0.05 V - allows DC-coupled interfacing with LVPECL, CML, and LVDS drivers without level-shifting circuitry. |
| Total Jitter (tTJ2BD) | 0.10–0.16 UIP-P at 3.125 Gbps with EQ+PE enabled - meets BER <1e−12 requirements for serial digital video and telecom backplanes. |
| Supply Current (ICC) | 77–90 mA at VCC = 3.3 V, PE/EQ off - enables low-power operation in multi-channel systems with thermal budget constraints. |
| ESD Rating (HBM) | ≥8 kV on LVDS I/O pins - protects adjacent components during handling and system integration without external TVS diodes. |
Pinout & Package
DS25CP102TSQX/NOPB uses the RGH0016A WQFN-16 package: 4 mm × 4 mm body, 0.8 mm max height, exposed thermal pad (DAP), 0.5 mm pitch, lead-free Sn finish, MSL Level-1, and flow-through pinout optimized for minimal trace length and impedance control on FR-4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0+, IN0− / IN1+, IN1− | Differential LVDS inputs | Accept LVDS/CML/LVPECL signals; internally terminated 100 Ω; wide common-mode range enables DC coupling. |
| OUT0+, OUT0− / OUT1+, OUT1− | Differential LVDS outputs | LVDS-compliant outputs with 100 Ω internal termination; support independent enable (EN0/EN1) and broadcast routing. |
| SEL0, SEL1 | Switch configuration control | LVCMOS inputs with 20 kΩ pulldown; define input-to-output mapping (IN0/IN1 → OUT0/OUT1) per truth table. |
| EN0, EN1 | Output enable control | LVCMOS inputs with 20 kΩ pulldown; disable respective outputs to reduce power and prevent bus contention. |
| PE | Transmit pre-emphasis select | LVCMOS input with 20 kΩ pulldown; selects OFF/ON pre-emphasis to compensate high-frequency loss in long traces. |
| EQ | Receive equalization select | LVCMOS input with 20 kΩ pulldown; selects OFF/ON equalization to restore signal integrity at receiver input. |
| VCC | Power supply | 3.0–3.6 V supply; decoupling required near pin 16 to suppress switching noise on high-speed paths. |
| GND (pins 5, DAP) | Ground reference | Low-inductance ground connection; DAP must be soldered to PCB thermal plane for θJC = 6.9°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Pin-configurable pre-emphasis & equalization | Two-level (Off/On) PE and EQ control enables adaptive signal conditioning for varying trace lengths (10″–60″ FR-4) without firmware or I²C overhead. |
| Fully differential non-blocking architecture | Any input can connect to any output simultaneously (e.g., IN0→OUT0 and IN1→OUT1), supporting flexible signal routing in SDI routers and telecom switches. |
| Integrated 100 Ω differential termination | Eliminates eight external 100 Ω resistors, reduces BOM count by ≥10 parts, and minimizes PCB area versus discrete termination solutions. |
| Wide input common-mode voltage range | 0.05 V to VCC−0.05 V supports direct DC-coupling to LVPECL (VOH ≈ VCC−1.3 V), CML (VCM ≈ VCC/2), and LVDS (VCM ≈ 1.2 V) sources. |
| Low-skew, low-jitter signal path | 25 ps max channel-to-channel skew and ≤0.16 UIP-P total jitter at 3.125 Gbps ensure timing margin for high-reliability serial video and data links. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS crosspoint switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9152ESE+ | 2×2 LVDS switch with fixed 2.5 Gbps max rate, no pre-emphasis/equalization, SOIC-16 package (10.3 mm × 7.6 mm). | Suitable for short-reach (<10″), lower-speed (≤2.5 Gbps) industrial links where adaptive signal conditioning is unnecessary. | Select MAX9152ESE+ when cost sensitivity outweighs signal integrity needs and board space permits larger SOIC footprint. |
| SN65LVCP22PWR | 2×2 LVDS repeater with integrated 2-tap FFE (not selectable EQ/PE), TSSOP-16, 3.125 Gbps rated, but no truth-table-based routing control. | Used in fixed-path repeater applications (e.g., cable extenders), not dynamic crosspoint routing with SEL/EN logic. | Choose SN65LVCP22PWR only for unidirectional repeater roles; DS25CP102TSQX/NOPB remains preferred for configurable routing with independent output enables. |
Compared with MAX9152ESE+ and SN65LVCP22PWR, DS25CP102TSQX/NOPB uniquely combines pin-selectable pre-emphasis/equalization, non-blocking 2×2 routing with truth-table control, and WQFN-16 space savings - making it the only option supporting adaptive 3.125 Gbps signal conditioning in compact SDI router and telecom line card designs.

FAQ
What is the maximum supported data rate for DS25CP102TSQX/NOPB?
The DS25CP102TSQX/NOPB is specified for operation from DC up to 3.125 Gbps, fully supporting OC-48 (2.488 Gbps), 3G-SDI (2.97 Gbps), and Fibre Channel (2.125 Gbps) protocols. Performance validation includes jitter and eye diagram testing at 3.125 Gbps using PRBS-23 patterns, confirming reliable operation at its rated maximum speed. The DS25CP102TSQX/NOPB maintains <0.16 UIP-P total jitter under worst-case conditions with both EQ and PE enabled.
Does DS25CP102TSQX/NOPB require external termination resistors?
No, DS25CP102TSQX/NOPB integrates 100 Ω differential termination resistors on all four differential I/O pairs (IN0±, IN1±, OUT0±, OUT1±), eliminating the need for eight external 100 Ω resistors. This reduces BOM count, saves PCB area, and improves impedance matching consistency. External termination is only required if custom termination values are needed for specific system-level impedance targets beyond the standard LVDS 100 Ω differential load.
How do the PE and EQ pins function on DS25CP102TSQX/NOPB?
The PE (pin 15) and EQ (pin 6) pins on DS25CP102TSQX/NOPB are LVCMOS inputs with internal 20 kΩ pulldown resistors, selecting between Off and On states for transmit pre-emphasis and receive equalization respectively. PE=1 enables pre-emphasis to boost high-frequency content before transmission over lossy traces; EQ=1 enables equalization to restore high-frequency loss at the receiver input. Both functions operate independently per channel and are validated up to 60″ FR-4 stripline loss.
What package type and thermal characteristics does DS25CP102TSQX/NOPB use?
DS25CP102TSQX/NOPB uses the RGH0016A WQFN-16 package: 4 mm × 4 mm body, 0.8 mm max height, exposed thermal pad (DAP), and lead-free Sn finish. Its thermal resistance is θJA = 41.8°C/W and θJC = 6.9°C/W, requiring the DAP to be soldered to a PCB thermal plane for optimal heat dissipation. Maximum package power dissipation is 2.99 W at +25°C, derating by 23.9 mW/°C above ambient.
Can DS25CP102TSQX/NOPB interface directly with LVPECL or CML drivers?
Yes, DS25CP102TSQX/NOPB accepts LVPECL and CML signals directly via DC-coupled interfaces due to its wide input common-mode voltage range (0.05 V to VCC−0.05 V). TI provides reference schematics showing direct connection to 3.3 V LVPECL (with 150–250 Ω pull-down) and CML (with 50 Ω termination to VCC), leveraging the device's internal 100 Ω differential termination. No level shifters or AC-coupling capacitors are required for compatibility.
