AS1154-BSOU

Drivers, Receivers, Transceivers Overview

The AS1154-BSOU is a dual LVDS line driver manufactured by ams OSRAM. It converts LVTTL/LVCMOS inputs to ANSI TIA/EIA-644 compliant LVDS outputs. The device supports data rates up to 800Mbps (400MHz) over controlled impedance media. It operates from a single +3.3V supply with a maximum differential output voltage of 450mV and a typical propagation delay of 1.268ns. The unit features a flow-through pinout in an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Flow-through pinout separates LVTTL/LVCMOS inputs from LVDS outputs to simplify PCB layout and reduce crosstalk.
• Current-steering architecture minimizes ground bounce and shoot-through current for enhanced noise margin.
• Outputs enter a high-impedance state when the device is unpowered or disabled.

Drivers, Receivers, Transceivers Applications

• Digital copiers and laser printers
• Cellular phone base stations and network switches/routers
• Backplane interconnects and clock distribution systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering code AS1154-BSOU corresponds to the tube delivery form, distinct from the tape and reel variant AS1154-BSOT. Confirm that the component meets RoHS compliance requirements before integration into the final assembly process.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low-power, high-speed point-to-point communication. Ensure the transmission medium utilizes approximately 100Ω termination resistors at the receiver input to match the characteristic impedance and optimize signal integrity.

Drivers, Receivers, Transceivers FAQ

What is the maximum guaranteed data rate?

The device is guaranteed to transmit data at speeds up to 800Mbps.

How should the VCC pin be bypassed?

Use high-frequency surface-mount ceramic capacitors of 0.1µF and 0.001µF in parallel, placed as close to the device as possible.

What happens to the outputs if the device is not powered?

The driver outputs enter a high-impedance state when the device is not powered or is disabled.
