DS10CP154TSQX/NOPB

Overview

The DS10CP154TSQX/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 a non-blocking architecture allowing any input to connect to any output, configurable via external pins or an SMBus interface. The device supports LVDS, CML, and LVPECL inputs with LVDS outputs, utilizing internally terminated 100Ω resistors. Operating on a single 3.3V supply within a -40°C to +85°C temperature range, it includes loss-of-signal monitoring and 8kV ESD protection in a compact LLP-40 package.

Feature Summary

• Non-blocking architecture enables flexible routing of any input to any output
• Dual configuration modes allow setup via external pins or System Management Bus
• Wide input common mode range supports DC coupling to LVDS, CML, and LVPECL drivers
• Integrated loss-of-signal circuitry detects open input fault conditions

Applications

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

Procurement Notes

Verify the specific suffix TSQX against the manufacturer's current datasheet to confirm package type and lead-free status. Ensure the design accommodates the restricted SMBus point-to-point limitation, as this component cannot share the bus with multiple slaves. Confirm that the LLP-40 package footprint aligns with the PCB layout guidelines provided in the official documentation.

Selection Notes

Select this component when a fully differential, non-blocking 4x4 switching matrix is required for LVDS signals up to 1.5 Gbps. It is suitable for designs needing both pin-level and SMBus configurability. Consider the DS10CP154A if the application requires sharing the SMBus with multiple slave devices, as the DS10CP154 supports only point-to-point connections.

Part Context

This part belongs to the DS10CP154 series of analog and digital crosspoint ICs from Texas Instruments (formerly National Semiconductor). It is optimized for high-speed signal integrity in lossy environments like FR-4 backplanes. The series focuses on low jitter and low skew performance for professional video and data distribution systems.

Replacement Considerations

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