Product details
Overview
DS90CP22MTX/NOPB from Texas Instruments is a 2×2 LVDS crosspoint switch IC designed for high-speed serial interconnect routing in backplane and board-level applications. 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 systems.
For engineers reviewing the DS90CP22MTX/NOPB datasheet, DS90CP22MTX/NOPB pinout, DS90CP22MTX/NOPB application, or DS90CP22MTX/NOPB equivalent, key selection criteria include differential jitter performance at 800 Mbps, TRI-STATE enable timing (TPZH/TPZL = 25.5–55 ns), LVPECL-compatible receiver inputs, and TSSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The DS90CP22MTX/NOPB implements a fully differential LVDS data path with no internal termination, enabling flexible external load matching (75 Ω or 100 Ω). Its mode control uses two SEL pins to configure 1:2 splitter, repeater, or crosspoint switching per Table 1 - all with sub-1.3 ns propagation delay (typ) and <1.2 ns switch time.
Receiver inputs accept LVDS, LVPECL (with attenuation), or PECL signals; outputs drive balanced 75 Ω or 100 Ω loads with 285–440 mV differential voltage (VOD) and 1.0–1.45 V common-mode offset (VOS). Enable pins (EN0/EN1) independently place each output pair into TRI-STATE, reducing supply current from 125 mA (active) to 55 mA (TRI-STATE).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 800 Mbps - supports high-speed serial links including LVDS-based camera interfaces and FPGA-to-FPGA interconnects |
| Peak-to-Peak Jitter | 65 ps (typ) at 800 Mbps with PRBS23−1 - ensures reliable eye opening in long-reach or multi-drop backplane traces |
| Propagation Delay | 1.3 ns (typ) - enables tight timing budgets in synchronous repeater or fan-out configurations |
| Output Skew | 35 ps (typ) channel-to-channel - maintains phase alignment across dual-output paths in clock/data distribution |
| Supply Voltage | +3.3 V (3.0–3.6 V range) - compatible with standard LVDS logic domains and eliminates need for auxiliary rails |
| Power Dissipation | 330 mW (typ) - enables thermal management in dense TSSOP-16 layouts without forced airflow |
| Input Compatibility | LVDS and LVPECL - allows direct interfacing with both TI SerDes transmitters and older PECL-based sources via simple resistive networks |
Pinout & Package
DS90CP22MTX/NOPB is housed in a 16-pin TSSOP (PW) package, 4.4 mm × 5.0 mm, 1.2 mm max height, with exposed pad for thermal enhancement. Pin 1 is located in Quadrant Q1 per tape-and-reel orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0+, IN0− | Differential LVDS input pair A | Accepts primary differential data stream; supports LVPECL with external attenuation |
| IN1+, IN1− | Differential LVDS input pair B | Enables redundant or alternate source selection in fault-tolerant routing |
| OUT0+, OUT0− | Differential LVDS output pair A | Configurable to mirror IN0 or IN1 based on SEL state; TRI-STATE controllable via EN0 |
| OUT1+, OUT1− | Differential LVDS output pair B | Independent output path; supports simultaneous 1:2 splitting or crosspoint routing |
| SEL0, SEL1 | Mode configuration inputs | Two-bit control selects 1:2 splitter, repeater, or switch function per Table 1 |
| EN0, EN1 | Output enable inputs | Active-high enables respective output pair; low places outputs in high-impedance TRI-STATE |
| VCC, GND | Power and reference | Single 3.3 V supply; requires local 0.01–0.1 µF RF bypassing per power pin |
| NC | No-connect | Two unassigned pins; must remain unconnected per datasheet guidance |
Key Features
| Feature | Design Value |
|---|---|
| Non-blocking 2×2 architecture | Any input can route to any output simultaneously - enables dynamic reconfiguration without signal interruption |
| LVPECL-compatible receivers | Accepts −0.3 V to +4 V differential input with <±100 mV threshold - eliminates level-shifter ICs when interfacing with legacy PECL sources |
| Configurable operating modes | Four distinct functions (1:2 splitter, repeater, crosspoint, 2:1 mux) selected by two digital control lines - reduces BOM count in multi-role systems |
| Low-skew differential outputs | 35 ps (typ) channel-to-channel skew - preserves signal integrity in parallel LVDS buses or clock distribution networks |
| Fast enable/disable timing | TPZH/TPZL = 25.5–55 ns - supports rapid output muting during hot-swap or failover events |

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 | Lower max data rate (400 Mbps), no LVPECL input support, identical TSSOP-16 footprint | Suitable only for cost-sensitive, lower-speed designs where input compatibility is not required | Select when 800 Mbps and LVPECL acceptance are unnecessary; verify timing margins at reduced speed |
| DS90CP22M-8/NOPB | Same silicon, SOIC-16 package (6.2 mm × 10.3 mm), higher thermal resistance, tube packaging | Better suited for prototyping or low-volume manual assembly where TSSOP reflow is impractical | Choose for hand-soldered evaluation or legacy SOIC-compatible boards; expect ~20% higher junction temperature at same power |
Compared with SN65LVDS22DR and DS90CP22M-8/NOPB, DS90CP22MTX/NOPB delivers full 800 Mbps capability and LVPECL input flexibility in a space-optimized TSSOP-16 tape-and-reel format ideal for automated SMT production of high-density interconnect systems.

FAQ
What is the maximum supported data rate for DS90CP22MTX/NOPB?
The DS90CP22MTX/NOPB supports up to 800 Mbps per channel with verified performance under PRBS23−1 pattern testing. This maximum rate is confirmed across the full operating temperature range (−40°C to +85°C) and supply voltage (3.0–3.6 V), with 65 ps (typ) peak-to-peak jitter measured at 800 Mbps using HP83483A scope module per SNLS053E test setup.
Does DS90CP22MTX/NOPB support LVPECL input signals directly?
Yes, DS90CP22MTX/NOPB accepts LVPECL input signals directly without external level shifting. Its LVDS receiver inputs tolerate common-mode voltages from 0.05 V to 3.25 V and differential thresholds within ±100 mV, enabling interoperability with LVPECL sources when used with appropriate termination networks as specified in the Application Information section.
What package type and dimensions does DS90CP22MTX/NOPB use?
DS90CP22MTX/NOPB uses a 16-pin TSSOP (PW) package measuring 4.4 mm × 5.0 mm with 0.65 mm lead pitch and 1.2 mm maximum height. It features a Q1 pin-1 orientation in tape-and-reel packaging (2500 units per reel), and includes an exposed thermal pad per TI's PW0016A outline drawing.
How many operating modes does DS90CP22MTX/NOPB support, and how are they selected?
DS90CP22MTX/NOPB supports four operating modes - 1:2 splitter, repeater, crosspoint, and 2:1 mux - selected via two digital control inputs (SEL0 and SEL1) per the Function Table in SNLS053E. Each combination maps deterministically to a routing configuration, enabling dynamic reconfiguration without reset or power cycle.
Can both output pairs of DS90CP22MTX/NOPB be placed into TRI-STATE independently?
Yes, DS90CP22MTX/NOPB provides independent TRI-STATE control for each output pair via dedicated EN0 and EN1 pins. Driving EN0 low places OUT0+/OUT0− into high-impedance state while OUT1+/OUT1− remains active, and vice versa - enabling selective output muting in multi-drop or shared-bus topologies.
