BU90R104-E2

Overview

The BU90R104-E2 is a Low Voltage Differential Signaling (LVDS) receiver integrated circuit manufactured by ROHM Semiconductor. It functions as a 5:35 deserializer, converting five serial LVDS input channels into thirty-five parallel LVCMOS output lines. The device supports data rates up to 784 Mbps with a maximum clock frequency of 112 MHz. It operates within a supply voltage range of 2.3 V to 3.6 V, typically at 3.3 V, and consumes approximately 52 mA of operating current. The component is housed in a TQFP-64 package and is rated for an industrial temperature range from -40°C to +85°C.

Feature Summary

• Serial-to-parallel conversion capability transforming five differential inputs into thirty-five single-ended outputs
• Support for high-speed data transmission via LVDS interface standards
• Compatibility with standard LVCMOS logic levels for downstream digital processing

Applications

• Digital home appliances such as liquid crystal televisions
• Office equipment including multifunction printers and copiers
• Computing and measurement devices requiring high-bandwidth data transfer
• Medical equipment utilizing digital signal interfaces

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm RoHS compliance and lead-free status. Confirm that the TQFP-64 package dimensions match the target PCB footprint requirements. Ensure the design accounts for the specified 52 mA typical current draw and thermal dissipation limits within the operating temperature range.

Selection Notes

Select this component when a system requires deserializing five LVDS lanes into a wide 35-bit parallel bus. It is suitable for applications needing data rates up to 784 Mbps. Consider the TQFP-64 package size constraints and the 2.3 V to 3.6 V supply voltage window during schematic design. Verify compatibility with the upstream LVDS driver specifications.

Part Context

This part belongs to the BU90R104 series of LVDS SerDes products from ROHM Semiconductor. The series offers a broad range of serializers and deserializers with transmission bit counts from 35 to 70 bits. These components are designed to reduce cable counts by enabling high-speed serial transmission at seven times the base rate, thereby minimizing electromagnetic interference through low swing modes.

Replacement Considerations

Check the official datasheet for direct pin-compatible substitutes within the same series. Verify if alternative deserializer configurations meet the 5-input to 35-output requirement without modifying the board layout.
