Overview
The DS90CP22M-8 is a digital crosspoint switch manufactured by Texas Instruments, formerly National Semiconductor. It features a 2x2 configuration with an 800 Mb/s data rate. Input types include LVDS, LVPECL, and PECL, while the output is LVDS. It operates on a single 3.3 V supply (3 V to 3.6 V) within a -40°C to +85°C temperature range. The device is housed in a 16-pin SOIC-Narrow package.
Feature Summary
- Provides flexible signal routing between two inputs and two outputs via a digital crosspoint architecture.
- Supports multiple differential input standards including LVDS, LVPECL, and PECL for broad compatibility.
- Delivers LVDS outputs suitable for low-voltage differential signaling applications.
Applications
- Signal routing in communication systems
- Video distribution networks
- Data acquisition equipment
Procurement Notes
Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the specific suffix '8' indicates the specified speed grade and package variant. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.
Selection Notes
Select this component when a 2x2 switching matrix is required for LVDS or PECL signals up to 800 Mbps. It serves as a direct replacement for legacy National Semiconductor parts. Consider the 16-SOIC package constraints for PCB layout. Verify that the 3.3V supply voltage aligns with the system power architecture.
Part Context
This part belongs to the DS90CP22 family of analog and digital crosspoint ICs. It is categorized under Communication & Networking ICs. The device is designed for high-speed signal switching in professional audio, video, and data transmission environments requiring reliable differential signal integrity.
Replacement Considerations
Direct substitutes include DS90CP22MX-8/NOPB and SN65LVCP22DR from Texas Instruments. These alternatives offer similar functionality and pinouts for retrofitting existing circuits without major redesign.
