Product details
Overview
DS90CP22MX-8/NOPB from Texas Instruments is a 2×2 LVDS crosspoint switch IC designed for high-speed serial interconnect routing in backplane and board-level differential signaling systems. It supports DC–800 Mbps operation with 65 ps (typ) peak-to-peak jitter, 35 ps (typ) output channel-to-channel skew, and operates from a single +3.3 V supply. It functions as a non-blocking switch, 2:1 mux, 1:2 demux, repeater, or signal splitter in fault-tolerant and serial bus distribution applications.
For engineers reviewing the DS90CP22MX-8/NOPB datasheet, DS90CP22MX-8/NOPB pinout, DS90CP22MX-8/NOPB application, or DS90CP22MX-8/NOPB equivalent, key selection criteria include its LVDS/LVPECL-compatible inputs, TRI-STATE enable control, 1.2 ns (typ) switch time, 1.3 ns (typ) propagation delay, and SOIC-16 package compatibility with industrial temperature range (−40°C to +85°C).
Technical Context
The DS90CP22MX-8/NOPB implements a fully differential LVDS data path with balanced output impedance and no internal fail-safe biasing-requiring external 10 kΩ pull-up/pull-down resistors on unused inputs. Its mode control uses two SEL pins to configure 1:2 splitter, repeater, or crosspoint switching per Table 1, with independent EN pins enabling TRI-STATE on each output pair.
It accepts LVDS and LVPECL input levels directly (LVPECL with no attenuation), features receiver input thresholds < ±100 mV, and delivers 365 mV (typ) differential output voltage into 75 Ω loads. AC timing includes 0.9–1.7 ns switch time, 25.5–55 ns enable-to-active transition, and 290–580 ps output transition times, all validated at 800 Mbps with PRBS23−1 pattern.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| SEL0, SEL1 | Mode Select Inputs | 2-bit control for 1:2 splitter, repeater, or crosspoint configuration (Table 1) |
| EN0, EN1 | Output Enable Inputs | Active-high enables respective output pair; logic low forces TRI-STATE |
| VCC, GND | Power and Ground | Single 3.3 V supply; requires local 0.01–0.1 µF RF bypass per supply pin |
| NC | No Connect | Two pins (pins 15, 16); must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Non-blocking 2×2 architecture | Enables any input-to-any-output connection without contention-critical for hot-swap and fault recovery |
| LVPECL-compatible inputs | Accepts LVPECL signals directly (no external level-shifting network required) |
| TRI-STATE output control | Independent EN0/EN1 pins allow dynamic isolation of each output pair during reconfiguration |
| Low pulse skew & jitter | 35 ps (typ) channel skew and 65 ps (typ) jitter preserve signal integrity at 800 Mbps |
| Configurable operating modes | Hardware-selectable 1:2 splitter, repeater, or crosspoint via SEL0/SEL1-no firmware needed |
Applications
| Backplane Signal Distribution | Fault-Tolerant Redundancy Switching |
|---|---|
|
Use Scenario: Distributing a single high-speed serial link (e.g., camera sensor output or FPGA SerDes stream) across multiple rack-mounted line cards. IC Role / Device Role / Timing Role: 1:2 splitter mode replicates the input signal identically to both OUT0 and OUT1 with ≤35 ps skew. Use Value: Eliminates need for active clock/data retiming; maintains sub-100 ps jitter budget across dual paths. |
Use Scenario: Switching between primary and backup data paths in telecom line cards or industrial controllers during failure detection. IC Role / Device Role / Timing Role: Crosspoint mode routes IN0→OUT0/IN1→OUT1 (or vice versa) under SEL control for seamless switchover. Use Value: 1.2 ns (typ) switch time enables sub-nanosecond path reconfiguration without packet loss. |
| LVDS Signal Repeating | Multi-Drop Backplane Fan-Out |
|
Use Scenario: Restoring signal amplitude and edge integrity after long trace runs (>30 cm) on FR4 backplanes. IC Role / Device Role / Timing Role: Repeater mode buffers and reshapes both channels independently with 1.3 ns propagation delay. Use Value: Compensates for trace loss while adding <225 ps pulse skew-preserving eye height and width. |
Use Scenario: Driving three or more LVDS receivers from one source in a multidrop backplane with 75 Ω line impedance. IC Role / Device Role / Timing Role: Operates in 1:2 splitter mode cascaded with additional DS90CP22 devices to expand port count. Use Value: Delivers 365 mV (typ) VOD into 75 Ω-better impedance match than standard LVDS drivers, reducing reflections. |
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 | 2×2 LVDS repeater only (no crosspoint or mux modes); 400 Mbps max; 16-pin SOIC | Limited to fixed-path buffering-cannot route IN0 to OUT1 or support SEL-based reconfiguration | Choose when only signal regeneration is needed and speed ≤400 Mbps suffices |
| DS90CP02MX/NOPB | 2×2 LVDS switch with identical pinout and modes, but rated for 600 Mbps (not 800 Mbps); same SOIC-16 package | Lower jitter (50 ps typ) at 600 Mbps, but cannot sustain full 800 Mbps operation | Choose for cost-sensitive designs where 600 Mbps bandwidth meets system requirements |
Compared with SN65LVDS22DR and DS90CP02MX/NOPB, DS90CP22MX-8/NOPB uniquely supports full 800 Mbps crosspoint switching with hardware-configurable modes and LVPECL input compatibility-making it the only option among the three for high-bandwidth fault-tolerant routing.

FAQ
What is the maximum supported data rate for DS90CP22MX-8/NOPB?
The DS90CP22MX-8/NOPB is characterized for DC–800 Mbps operation with 65 ps (typ) peak-to-peak jitter using a PRBS23−1 pattern. This maximum rate is validated across the full −40°C to +85°C temperature range and 3.0–3.6 V supply, making DS90CP22MX-8/NOPB suitable for demanding serial interconnect applications such as camera sensor interfaces and FPGA-to-FPGA links.
Does DS90CP22MX-8/NOPB support LVPECL input signals without external components?
Yes, DS90CP22MX-8/NOPB accepts LVPECL input levels directly at its IN0+/IN0− and IN1+/IN1− pins-no external termination or level-shifting networks are required. The receiver input threshold remains < ±100 mV across common-mode voltages from 0.05 V to 3.25 V, ensuring reliable detection of LVPECL swings referenced to VCC−2 V.
How does the mode selection work on DS90CP22MX-8/NOPB?
DS90CP22MX-8/NOPB uses two digital control inputs-SEL0 and SEL1-to select among four operating modes defined in Table 1: 00 = 1:2 splitter (IN0 duplicated), 01 = repeater (IN0→OUT0, IN1→OUT1), 10 = crosspoint (IN1→OUT0, IN0→OUT1), 11 = 1:2 splitter (IN1 duplicated). These are hardwired logic inputs with internal pull-downs, requiring no clock or configuration protocol.
Can DS90CP22MX-8/NOPB outputs be individually disabled?
Yes, DS90CP22MX-8/NOPB provides independent TRI-STATE control via EN0 and EN1 pins. Driving EN0 low disables OUT0+/OUT0− (high-impedance), while EN1 low disables OUT1+/OUT1−. This allows dynamic output isolation during system reconfiguration without affecting the other channel's operation or supply current.
What package type and footprint does DS90CP22MX-8/NOPB use?
DS90CP22MX-8/NOPB is supplied in a 16-pin SOIC (D) package with 1.27 mm pitch, 7.5 mm × 10.3 mm body size, and 1.75 mm max height. It shares the same land pattern as industry-standard SOIC-16 devices and is compatible with automated SMT assembly, including reflow profiles up to 260°C (MSL Level-1).
