SK4414
Quad Buffer/Receiver
HIGH-PERFORMANCE PRODUCTS
Description
ꢀeatures
The SK4414 is an extremely fast, stable and accurate •
low skew quad buffer or cable driver / receiver. It can •
asychronously pass four distinct signals, or it can •
resynchronize them to a common clock. In addition, •
all four outputs may be asynchronously enabled or
disabled. All of the D flip-flops are triggered on the
rising edge of the CLK input.
Quad Buffer/Receiver
3 GHz Fmax
3.3V / 5.2V Compatible
Available in 32 lead, 5mm X5mm, TQFP
Package
Application Notes
The SK4414 has 100Ω input termination resistors
across each of the four inputs to help reduce system
component count and increase integration.
AN1001 - EPIC Family Product Line
AN1003 - Termination Techniques for ECL / LVECL
PECL / LVPECL Devices
AN1004 - Interfacing Between LVDS and ECL /
LVECL / PECL / LVPECL
The SK4414 uses 50Ω outputs with sink/source
capability, and is optimized for applications that require:
• Point to point, double terminated, timing
critical lines
• Point to point, series terminated, timing
critical lines
