Description
A 1.8V LVDS, crystal controlled, low
current, low jitter oscillator with precise
rise and fall times demanded in network-
ing applications, such as Gigabit Ethernet
and Fibre Channel. The Tri-State func-
tion enables the output to go high im-
pedance. Device is packaged in an 8-
pin DIP compatible resistance welded,
all metal grounded case, to reduce EMI.
