AS1154-BSOT

Drivers, Receivers, Transceivers Overview

The AS1154-BSOT 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) with a maximum differential pulse skew of 250ps. It operates on a single +3.3V supply within a -40°C to +85°C temperature range. Electrical characteristics include a typical propagation delay of 1.268ns and a no-load supply current of 2mA to 3.5mA. The component is housed in an 8-pin SOIC package.

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-BSOT corresponds to the tape and reel delivery form, distinct from the tube variant AS1154-BSOU. Confirm RoHS compliance status directly with the manufacturer prior to procurement. Ensure the specific batch matches the required moisture sensitivity level and storage conditions defined in the datasheet absolute maximum ratings.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low-power, high-speed point-to-point communication over controlled impedance media. The dual-channel configuration is suitable for converting standard logic levels to differential signals. Verify that the system termination resistance falls between 90Ω and 132Ω to ensure proper voltage swing generation given the current-steering output design.

Drivers, Receivers, Transceivers Part Context

The AS1154 belongs to the Austriamicrosystems LVDS interface family, designed alongside complementary receivers such as the AS1157 and AS1158. This series targets high-speed data transmission with reduced electromagnetic interference. The BSOT suffix specifically denotes the tape and reel packaging format intended for automated surface-mount assembly processes.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer for direct replacements or evaluate other dual LVDS drivers from the same product family if availability is constrained.

Drivers, Receivers, Transceivers FAQ

What is the maximum guaranteed data rate for the AS1154?

The device is guaranteed to transmit data at speeds up to 800Mbps, which corresponds to a maximum operating frequency of 400MHz.

How does the AS1154 handle power-off states?

When the device is not powered or is disabled, the driver outputs enter a high-impedance state, preventing unwanted loading on the bus.

What input voltage levels does the AS1154 accept?

The AS1154 accepts LVTTL and LVCMOS input levels, translating them into LVDS output signals conforming to the ANSI TIA/EIA-644 standard.
