Product details
Overview
DS25CP102TSQ/NOPB from Texas Instruments is a 3.125 Gbps 2×2 LVDS crosspoint switch with integrated transmit pre-emphasis and receive equalization, designed for high-speed signal routing across lossy FR-4 backplanes and balanced cables. It features fully differential non-blocking architecture, on-chip 100 Ω input/output termination, and supports DC-coupled interfacing to LVDS/CML/LVPECL sources in broadcast or point-to-point configurations.
For engineers reviewing the DS25CP102TSQ/NOPB datasheet, DS25CP102TSQ/NOPB pinout, DS25CP102TSQ/NOPB application, or DS25CP102TSQ/NOPB equivalent, this device serves as a low-jitter, low-skew signal router for SD/HD/3G-SDI routers, OC-48/STM-16 systems, and clock/data multiplexing where deterministic jitter <22 ps (peak-to-peak) and channel-to-channel skew ≤25 ps are required.
Technical Context
The DS25CP102TSQ/NOPB implements a pin-configurable, fully differential, non-blocking 2×2 switch matrix with independent enable control per output (EN0/EN1) and configurable routing via SEL0/SEL1 pins. Its internal 100 Ω differential termination eliminates external resistors and minimizes insertion loss on both inputs and outputs.
Transmit pre-emphasis (PE pin) and receive equalization (EQ pin) each offer two discrete levels (Off/On), enabling adaptive compensation for up to 40-inch FR-4 stripline loss. The device operates from a single 3.0–3.6 V supply and maintains LVDS-compliant output swing (250–450 mV) and common-mode range (0.05 V to VCC − 0.05 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 3.125 Gbps - supports OC-48, STM-16, and 3G-SDI serial data rates without retiming |
| Differential Propagation Delay | 345–500 ps - ensures tight timing alignment between channels for synchronous routing |
| Channel-to-Channel Skew | ≤25 ps - enables precise phase matching in multi-lane or parallel clock distribution paths |
| Total Jitter (3.125 Gbps) | 0.05–0.11 UIP-P - meets stringent eye-opening requirements for serial video and telecom links |
| Supply Current (Active) | 77–90 mA at 3.3 V - enables low-power operation in dense high-speed PCB layouts |
| ESD Protection | ±8 kV HBM on LVDS I/O - safeguards against handling-induced damage during board assembly |

Pinout & Package
DS25CP102TSQ/NOPB uses a 4 mm × 4 mm WQFN-16 package (RGH0016A) with exposed thermal pad (DAP) and flow-through pinout optimized for minimal trace stubs and simplified PCB routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| EN0, EN1 | Output Enable Control | LVCMOS inputs with 20 kΩ pulldown; disable respective output to high-impedance state |
| PE, EQ | Signal Integrity Control | LVCMOS pins enabling/disabling pre-emphasis (PE) or equalization (EQ) independently |
| VCC, GND, DAP | Power & Ground | Single 3.0–3.6 V supply; DAP must be soldered to PCB ground plane for thermal/mechanical stability |
Key Features

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+ | Fixed-function 2×2 LVDS switch; no pre-emphasis or equalization; 2.5 Gbps max data rate | Suitable for shorter interconnects (<15″ FR-4) where signal integrity compensation is unnecessary | Select when cost sensitivity outweighs need for adaptive loss compensation and 3.125 Gbps support |
| SN65LVCP22PWR | 2×2 LVDS repeater with fixed equalization only; no transmit pre-emphasis; 3.125 Gbps rated | Optimized for passive cable driving rather than backplane routing; lacks independent output enable | Prefer when replacing legacy TI LVDS repeaters and EN0/EN1 control is not required |
Compared with MAX9152ESE+ and SN65LVCP22PWR, DS25CP102TSQ/NOPB uniquely combines programmable PE/EQ, independent output enables, and full 3.125 Gbps operation in a space-saving WQFN-16 package-making it the only option supporting adaptive loss compensation in compact SDI or telecom line cards.

FAQ
What is the maximum supported data rate for DS25CP102TSQ/NOPB?
The DS25CP102TSQ/NOPB is characterized and specified for operation up to 3.125 Gbps, meeting the requirements of 3G-SDI (SMPTE 424M) and OC-48/STM-16 standards. Performance metrics including jitter, skew, and propagation delay are guaranteed across this full rate range under recommended operating conditions (VCC = 3.0–3.6 V, TA = −40°C to +85°C).
Does DS25CP102TSQ/NOPB require external termination resistors?
No, DS25CP102TSQ/NOPB integrates 100 Ω differential termination on all four LVDS inputs and outputs. This eliminates the need for eight external 100 Ω resistors, reduces PCB area, simplifies layout, and improves impedance matching consistency across process, voltage, and temperature variations.
How does the pre-emphasis and equalization function in DS25CP102TSQ/NOPB?
DS25CP102TSQ/NOPB provides two discrete levels (Off/On) for both transmit pre-emphasis (controlled by PE pin) and receive equalization (controlled by EQ pin). These functions compensate for frequency-dependent loss in FR-4 backplanes-PE boosts high-frequency content at the transmitter, while EQ amplifies attenuated high frequencies at the receiver-enabling reliable 3.125 Gbps operation over up to 40-inch striplines.
What package type and footprint does DS25CP102TSQ/NOPB use?
DS25CP102TSQ/NOPB uses the WQFN-16 (RGH0016A) package: 4 mm × 4 mm body, 0.8 mm max height, with an exposed thermal pad (DAP). Its flow-through pinout-inputs on top/bottom edges, outputs on left/right-minimizes trace stubs and supports straightforward PCB routing in high-density applications.
Can DS25CP102TSQ/NOPB interface directly with LVPECL or CML drivers?
Yes, DS25CP102TSQ/NOPB accepts LVPECL and CML signals directly via DC coupling thanks to its wide input common-mode voltage range (0.05 V to VCC − 0.05 V). The internal 100 Ω termination matches standard differential driver impedances, and no external level-shifting components are needed when interfacing with typical 3.3 V or 2.5 V CML/LVPECL sources.
