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.

FIN1104

LVDS 4 Port High Speed Repeater

General Description

This 4 port repeater is designed for high speed intercon-

nects utilizing Low Voltage Differential Signaling (LVDS)

technolo gy. T he F IN1104 accep ts an d ou tpu ts LVDS levels

with a typical differential output swing of 330 mV which pro-

vides low EMI at ultra low power dissipation even at high

frequencies. The FIN1104 provides a VBB reference for AC

coupling o n th e inpu ts. In addition the F IN1104 can dir ectl y

accept LVPECL, HSTL, and SSTL-2 for translation to

LVDS.

Features

■Greater than 800 Mbps data rate

■3.3V power supply operation

■3.5 ps maximum random jitter and 135 ps maximum

deterministic jitter

■Wide rail-to-rail common mode range

■LVDS receiver inputs accept LVPECL, HSTL, and

SSTL-2 directly

■Ultra low power consumption

■20 ps typical channe l -to-c ha nn el skew

■Power off protection

■> 7.5 kV HBM ESD Protection

■Meets or exceeds the TIA/EIA-644-A LVDS standard

■Available in space savi ng 24- Le ad TSS OP package

■Open circuit fail safe protection

■VBB reference output

Ordering Code:

Devices also available in Tape and R eel. Specify by appending suffix letter “X” to the ordering code.
