Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

FIN1048
3.3V LVDS 4-Bit Flow-Through
High Speed Differential Receiver
General Description
Features
This quad receiver is designed for high speed interconnect
utilizing Low Voltage Differential Signaling (LVDS) technology. The receiver translates LVDS levels, with a typical differential input threshold of 100mV, to LVTTL signal levels.
LVDS provides low EMI at ultra low power dissipation even
at high frequencies. This device is ideal for high speed
transfer of clock and data.
■ Greater than 400Mbs data rate
The FIN1048 can be paired with its companion driver, the
FIN1047, or any other LVDS driver.
■ Power-Off protection
■ Flow-through pinout simplifies PCB layout
■ 3.3V power supply operation
■ 0.4ns maximum differential pulse skew
■ 2.5ns maximum propagation delay
■ Low power dissipation
■ Fail safe protection for open-circuit, shorted and terminated conditions
■ Meets or exceeds the TIA/EIA-644 LVDS standard
■ Pin compatible with equivalent RS-422 and LVPECL
devices
■ 16-Lead SOIC and TSSOP packages save space
