Product details
Overview
DS90CP22M-8/NOPB from Texas Instruments is a 2×2 LVDS crosspoint switch optimized for high-speed serial interconnects up to 800 Mbps. It supports non-blocking switching, 1:2 signal splitting, 2:1 multiplexing, and repeater operation with differential LVDS I/O, 3.3 V single supply, and <330 mW typical power dissipation. Used in backplane fan-out and fault-tolerant system path switching.
For engineers reviewing the DS90CP22M-8/NOPB datasheet, DS90CP22M-8/NOPB pinout, DS90CP22M-8/NOPB application, or DS90CP22M-8/NOPB equivalent, key selection criteria include channel-to-channel skew (35 ps typ), input threshold (<±100 mV), fast propagation delay (1.3 ns typ), TRI-STATE enable control, and compatibility with LVPECL inputs.
Technical Context
The DS90CP22M-8/NOPB implements a fully differential LVDS data path with no internal termination, supporting DC–800 Mbps operation using PRBS-23 patterns. Its function table defines four modes via two SEL pins: 1:2 splitter (SEL0=SEL1=0 or 1), repeater (SEL0=0/SEL1=1), and crosspoint switch (SEL0=1/SEL1=0).
Each LVDS output pair (OUT0+/−, OUT1+/−) features balanced impedance, configurable TRI-STATE via dedicated EN pins, and output skew of ≤80 ps (max) in 1:2 mode. Receiver inputs accept LVDS, LVPECL, or attenuated PECL signals with common-mode range from 0.05 V to 3.25 V and fail-safe biasing support via external resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 800 Mbps - supports full-rate serial links without retiming or buffering |
| Supply Voltage | 3.3 V ±10% - single-rail operation compatible with standard LVDS logic domains |
| Propagation Delay | 1.3 ns (typ) - enables tight timing budgets in multi-stage signal distribution paths |
| Output Skew | 35 ps (typ) - ensures matched edge alignment across outputs for synchronous fan-out |
| Jitter (Pk-Pk) | 65 ps (typ) at 800 Mbps - preserves eye integrity in high-speed point-to-point or multidrop topologies |
| Power Dissipation | 330 mW (typ) - low thermal load suitable for dense PCB layouts and uncooled industrial enclosures |

| VCC, GND | Power & Ground | Single 3.3 V supply rail; requires local 0.1 µF RF + bulk tantalum bypass per pin |
| NC | No Connect | Two pins (pins 15, 16) are unused; must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Non-blocking crosspoint architecture | Enables any input-to-any-output connection without contention, critical for hot-swap and redundancy management |
| LVPECL-compatible receiver inputs | Eliminates need for level-shifting circuitry when interfacing with legacy PECL/LVPECL sources |
| Individual output TRI-STATE control | Allows dynamic isolation of one output while maintaining signal integrity on the other-essential for shared-bus arbitration |
| Low pulse skew & jitter performance | 35 ps typ channel-to-channel skew and 65 ps typ peak-to-peak jitter preserve signal fidelity at 800 Mbps |
| Backplane-optimized drive strength | Delivers 365 mV differential output into 75 Ω, improving match to loaded multidrop line impedances vs. standard 100 Ω LVDS |
Applications
| Rack-Mounted Backplane Signal Distribution | Fault-Tolerant Redundancy Switching |
|---|---|
Use Scenario: Distributing a single high-speed serial link (e.g., camera sensor output or FPGA fabric stream) to multiple downstream processing modules across a 19-inch rack backplane. IC Role / Device Role / Timing Role: 1:2 LVDS signal splitter with matched propagation delay and low skew to maintain deterministic timing across parallel paths. Use Value: Eliminates need for discrete buffer chains; maintains eye opening >60% at 800 Mbps over 30 cm FR4 traces due to low jitter and balanced drive. | Use Scenario: Seamless switchover between primary and backup data paths in avionics or industrial control systems where continuity of serial telemetry is mission-critical. IC Role / Device Role / Timing Role: 2:1 LVDS multiplexer with sub-1.2 ns switch time and fail-safe input handling to prevent glitches during transition. Use Value: Enables <10 ns interruption window during path change; SEL-controlled routing avoids metastability risks inherent in asynchronous switching. |
| High-Speed Serial Repeater | LVDS Interface Isolation Layer |
Use Scenario: Restoring signal amplitude and timing integrity across long PCB traces (>20 cm) or between stacked boards with connector-induced loss. IC Role / Device Role / Timing Role: Two-channel LVDS repeater operating in pass-through mode with 1.3 ns propagation delay and <225 ps pulse skew. Use Value: Recovers degraded eye height from 150 mV to >300 mV differential swing, enabling reliable sampling at downstream receivers. | Use Scenario: Galvanically isolating LVDS signal domains between noisy motor-control sections and sensitive analog acquisition subsystems on shared PCBs. IC Role / Device Role / Timing Role: Signal buffer with fully differential I/O and independent enable control to break ground loops while preserving timing relationships. Use Value: Prevents common-mode noise coupling between domains; TRI-STATE capability allows safe power sequencing during startup/shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS crosspoint switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS22DR | Same 2×2 LVDS crosspoint topology but rated to 600 Mbps max; higher 450 mW power; no LVPECL input support | Limited to lower-speed designs; lacks fail-safe biasing flexibility and backplane-optimized 75 Ω drive | Choose when cost sensitivity outweighs speed or multidrop compatibility requirements |
| MAX9110ESE+ | 2×2 LVDS mux with 400 Mbps rating; integrated 100 Ω termination; no TRI-STATE outputs or SEL-based mode control | Suitable only for fixed-function muxing; no repeater or splitter modes; no independent output disable | Select only for simple point-to-point muxing where board space is constrained and termination integration is prioritized |
Compared with SN65LVDS22DR and MAX9110ESE+, the DS90CP22M-8/NOPB uniquely delivers 800 Mbps operation, LVPECL input tolerance, programmable 1:2/2:1/repeater modes, and individual TRI-STATE control-making it the only option qualified for high-speed backplane fan-out and fault-tolerant path switching in industrial and telecom infrastructure.

The DS90CP22M-8/NOPB supports up to 800 Mbps with PRBS-23 pattern at 3.3 V supply and 25°C ambient. This rating is validated per AC Electrical Characteristics in the official TI datasheet SNLS053E, with 65 ps typical peak-to-peak jitter and 1.3 ns typical propagation delay confirming full-rate operation capability.
Does DS90CP22M-8/NOPB support LVPECL input signals directly?
Yes, DS90CP22M-8/NOPB LVDS receiver inputs accept LVPECL signals directly without external level shifting. The input common-mode range extends from 0.05 V to 3.25 V, and the differential threshold remains within ±100 mV, enabling interoperability with +3.3 V LVPECL drivers per TI's Application Information section.
How many operational modes does DS90CP22M-8/NOPB support, and how are they selected?
DS90CP22M-8/NOPB supports three modes-1:2 splitter, repeater, and crosspoint switch-selected via two CMOS/TTL SEL inputs (SEL0, SEL1) per Table 1 in the datasheet. Mode mapping is deterministic: SEL0=0/SEL1=0 → IN0→both outputs; SEL0=0/SEL1=1 → IN0→OUT0, IN1→OUT1; SEL0=1/SEL1=0 → crosspoint routing.
Can both outputs of DS90CP22M-8/NOPB be independently disabled?
Yes, DS90CP22M-8/NOPB provides independent TRI-STATE control for each output pair via dedicated EN0 and EN1 pins. Driving EN0 low disables OUT0+/−; driving EN1 low disables OUT1+/−. This allows dynamic output isolation without affecting the other channel's operation or power state.
