DS10CP154TSQ/NOPB

Overview

The DS10CP154TSQ/NOPB is a 1.5 Gbps 4x4 LVDS digital crosspoint switch designed for high-speed signal routing over FR-4 backplanes and balanced cables. It features fully differential, non-blocking architecture with internal 100Ω termination on all inputs and outputs. The device supports DC-coupled interfaces to CML, LVDS, and LVPECL signals via a wide common mode range. Configuration is achieved through external pins or an SMBus interface, which also enables Loss of Signal (LOS) monitoring. Operating at 3.3V, it utilizes a 6 mm x 6 mm LLP-40 package.

Feature Summary

• Non-blocking architecture allows any input to connect to any output
• Configurable via external pins or System Management Bus (SMBus)
• Built-in LOS circuitry detects open input fault conditions
• On-chip 100Ω termination minimizes insertion and return losses

Applications

• High-speed channel select applications
• Clock and data buffering and muxing
• SD/HD SDI routers

Procurement Notes

Verify the specific ordering suffix TSQ against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Ensure the design accounts for the restricted SMBus point-to-point limitation, as this variant cannot share the bus with multiple slave devices. Confirm that the application environment operates within the specified temperature and voltage ranges.

Selection Notes

Select this component when a 4x4 switching matrix is required for LVDS signals up to 1.5 Gbps. It is suitable for designs needing flexible configuration via hardware pins or SMBus control. Consider the DS10CP154A if the system requires sharing the SMBus among multiple slave devices, as the standard version does not support multi-slave topologies.

Part Context

This part belongs to the DS10CP154 series of analog and digital crosspoint ICs manufactured by Texas Instruments. It is optimized for high-speed signal routing in professional video and telecommunications equipment. The device integrates low jitter performance and power management features to support efficient board layouts in dense electronic systems.

Replacement Considerations

The DS10CP154A is recommended for applications requiring multiple SMBus slave devices on the same bus. Verify pin compatibility and electrical characteristics before substituting other crosspoint switches.
